Who this is for
If yous're driving an older automobile without built-in Bluetooth and you desire to be able to jam out to your tunes and make calls over your machine's speakers without having to install a new car stereo, you have a few options. The three virtually common ways to accomplish this are with a Bluetooth receiver that plugs into a car's auxiliary-audio (aux-in) port; with an FM transmitter that takes your phone'southward Bluetooth-sound output and broadcasts it over FM radio waves that your car stereo can pick upwardly; or with a defended Bluetooth speakerphone. The first two options allow you listen to music or phone calls over your car'south speakers; the tertiary option, a Bluetooth speakerphone, has its own built-in speakers and is designed with ameliorate call quality in mind.
Which type should yous get?
None of these options is perfect, but each is portable, cheap (compared with the cost of replacing your motorcar stereo), and relatively hassle-complimentary. Depending on the system you cull, you may have to cede your car's 12 V accessory-power outlet (though some kits have laissez passer-through USB ports for charging other devices) or regularly recharge the kit. And although sound quality varies beyond the types of add-on Bluetooth kits—the worst ones won't audio as good as if you were connecting directly to a car stereo with built-in Bluetooth—one of these volition more than suffice until you lot're set up to upgrade your auto or its stereo. To determine the best organisation for your needs, consider the post-obit things:
- If your car has an auxiliary-audio input jack (which looks similar a headphone jack), go an aux-in kit. These devices are small and easy to use, and they let you control music and phone calls using buttons on the receiver itself. And because they use a wired connection to your car's stereo, aux-in kits offering the best overall audio quality.
- If you don't take an aux-in jack, and yous'll exist listening to music more taking phone calls, an FM transmitter is your all-time selection. FM transmitters transmit your phone'due south Bluetooth audio over FM radio frequencies, so your car's radio can pick them upwardly. Because they add together another layer of potential interference, these models can take problems with static and don't sound as good equally a line-in kit, just our pick offers an unusually strong connectedness. Call quality won't be excellent, considering you can't motility the microphone on these units to an optimal location, but music or podcasts sound good.
- If you don't have an aux-in jack, and you value call quality over music quality—or if your chief use is for phone calls—become a defended speakerphone. Speakerphones are portable and come the closest to creating a truthful easily-gratuitous-telephone experience, making them ideal for phone conversations. Some of them too allow you to control music, answer telephone calls, or send text messages without having to touch your telephone. Withal, they're not as good every bit the other 2 styles for music streaming; they usually sound like a louder version of the speakers built into your phone.
Other options
Though a Bluetooth auto kit is the easiest and least expensive way to add Bluetooth to your car's stereo, it isn't the but option. If you also want a GPS navigator for turn-by-turn directions, many models—such every bit our top car-GPS option—include Bluetooth connectivity for conducting hands-free calls. Only you tin can't stream music on them, and most cost considerably more than the kits we tested here, so we don't recommend them equally a general Bluetooth upgrade.
Alternatively, if yous plan on keeping your automobile for at least a few more years, you lot could upgrade your car stereo; doing so volition give you built-in Bluetooth connectivity along with—depending on the stereo—useful features such as satellite radio, Siri or Google Banana integration, and even Apple CarPlay and Android Auto. This approach volition cost more a Bluetooth kit, simply the resulting Bluetooth experience volition be much more seamless, and you'll get a great new car stereo in the process.
How we picked and tested
We began past reading reviews for as many devices as we could find. CNET and PCMag are amongst the few places y'all can find reviews of Bluetooth car kits, and even and so, the reviews on those sites tend to be years old. So we likewise read Amazon customer reviews, which are more contempo and generally more numerous. Whether the product was an aux-in kit, an FM transmitter, or a speakerphone, the nigh important thing nosotros looked for in reviews was ease of use and how shut the product came to a native Bluetooth feel in your car. With that in mind, we prepare out to observe the most promising candidates for each blazon of kit.
When deciding which models to exam (and besides during testing), we focused on the following criteria:
- Sound quality: This is past far the most important factor in purchasing a Bluetooth automobile kit. There'due south no point in having the power to heed to music and podcasts from your telephone or to take phone calls unless y'all have clear, functional, and enjoyable audio—both for listening and for speaking. (Because Bluetooth speakerphones are designed specifically for phone calls, with those models we focused less on music capabilities and more than on audio quality for calls.)
- Music and phone-call functionality: If you want to replicate a native Bluetooth experience, you demand a model that can play music as well as make telephone calls. We didn't consider any kit that lacked either of these features.
- Ease of utilise: We specifically looked for models that automatically reconnect with a paired telephone when you starting time the car, and for those with clearly labeled buttons and other controls.
- Power: Most kits rely on USB adapters to plug into your motorcar'southward 12 5 accompaniment ability (aka "cigarette lighter") outlet. We didn't consider any kit that didn't include at least ane USB-charging port that you can utilise while the transmitter is plugged in—if you're using your phone for streaming and conversations, it stands to reason that yous will desire to charge it, too.
- Reputation: These kits are cheap and plentiful. Amazon sells hundreds of no-name brands that offer their ain take on these products. With that in mind, we limited our well-nigh recent sweep to brands that take a reputation for expert quality and service and that offer a reliable warranty.
- Owner reviews: Nosotros eliminated anything with an overwhelming number of negative owner reviews, or whatsoever model that had accumulated a suspicious number of reviews over a short period of time.
Our testing procedure has remained the same across several iterations of this guide. To evaluate the outgoing audio quality and sound clarity of telephone calls, we left voicemails—one with the windows upwardly and another with the windows downwards—while driving down the highway at about 55 mph. We distributed the audio files for those voicemail letters to a panel of Wirecutter editors and writers who ranked them and left comments on audio quality. For earlier versions of this guide, nosotros conducted our tests in a 2013 Toyota Prius C, and for the latest ii we used a 2006 Honda Borough.
For our latest update, we used a similar approach to test music quality. In order to avoid the subjective quirks of car stereos, nosotros connected each aux-in kit to a Focusrite Scarlett 2i2, our top selection audio interface, and recorded a clip of a song streaming over Bluetooth from a phone. We then distributed those files—forth with the original, uncompressed song prune as a blind control—to Wirecutter editors and writers, who ranked them on the sound quality.
Our aux-in selection: Besign BK01 Bluetooth Auto Kit
Our pick
After testing 30 models in recent years, nosotros've plant that the Besign BK01 Bluetooth Automobile Kit provides the all-time combination of sound quality, phone usability, and features. It produced the best music quality, as well as proficient telephone quality, giving information technology a distinct edge over the other models.
Nosotros checked the BK01'southward music quality by playing audio through the same automotive sound system that a Wirecutter staffer has used for checking studio-recording mixes on a car stereo, and we found that the subtleties in the music shone through the mode they were intended to—nosotros didn't hear any buzzing or distortion. Though nosotros tin can't guarantee that every vehicle volition be free of interference, the BK01 comes with an optional ground-loop isolation cable that should cancel out any hum. We asked seven other staffers to rate the audio, too, and they found that the loss of quality was barely noticeable when comparing a song played over the BK01 to the original recording.
In terms of phone-telephone call sound, the Besign'due south outgoing-call quality was clear enough (inasmuch equally any phone telephone call always is), although information technology was slightly tinnier and more distorted than with another models, including the Roav by Anker Bluetooth Receiver and the Taotronics TT-BR04. The change in audio quality (and volume) when switching from music to phone could be jarring, but this was something we also experienced with every other model we tested. If y'all program on using your Bluetooth machine kit for telephone calls more for music, we recommend that you check out our dedicated speakerphone choice.
The Besign BK01 is also like shooting fish in a barrel to fix and use. When yous first plug it into your car'south 12 Five port, it automatically turns on in pairing mode; other models we tested require yous to push a combination of buttons for pairing (this can also increase the hazard that you'll accidentally hit those buttons during utilize, setting yous back to pairing way while on the road). Once the Besign is paired with your telephone, it will immediately reconnect each time you plough the car on. Many models hope this kind of automatic connection, merely the Besign actually pulled information technology off consistently in our tests. The but drawback is that it's mildly inconvenient if you share a car with some other person—the BK01 reconnects to the final device it was connected to. If information technology connects to the wrong telephone—or doesn't connect, for some reason—you can disable the Bluetooth on the other telephone, or re-pair by but holding downwards the large center push until you hear a long tone (you might need to press the multifunction button one more fourth dimension to actually reconnect; information technology can exist a chip finicky).
The Besign's modest, unobtrusive design is sleek and modern, and this model comes with two magnetic mounts that allow you to easily remove the BK01 from the dash to protect confronting theft, or to use it in a different car. Two linked wires extend from the main disc: One connects to your automobile'due south aux-in port and the other to the included 12 Five USB charger. That charger too has an additional USB port, and so you can charge your phone while listening to music, if needed (though we besides like that y'all can disconnect the Besign from its included charger and use information technology with ane that charges your phone more chop-chop). Like most of the other aux-in kits we tested, the Besign BK01 tin can as well pair with ii phones at once, making it great for road trips or alternating playlists with those of your friends.
Two clearly marked buttons on the front of the unit offering rail-forward and track-back command—which may sound like an obvious feature, but information technology was one that we found lacking on several models, including the Roav by Anker Bluetooth Receiver and the Anker Soundsync A3352. The large multifunction button in the center of the Besign lets you pause and resume music or end a telephone call, and it's easy to find and press by feel, even when yous're keeping your eyes on the road. You can also hold this push button down for two seconds to trigger Siri or Google Assistant, depending on your telephone (the Anker models we tested couldn't do this, either). Fifty-fifty though this is a nice convenience, it's not entirely necessary, since many phones already offer hands-free digital assistants. Still, this tin come in handy if you want to get directions or make outgoing calls using your phone's phonation banana via the BK01. By contrast, the features on some competitive models are more express; a few (including some FM transmitters that we tested) only permit y'all take incoming calls or phone call dorsum the number that you last dialed or missed.
Flaws simply not dealbreakers
The Besign's built-in echo- and racket-cancellation features are far from perfect, resulting in a slightly shrill sound on outgoing sound. That said, approachable vocalism quality is even so easy to empathize, and information technology beats that of most of the other aux-in models we tested, except the Taotronics TT-BR04 and the Roav past Anker Bluetooth Receiver (which sounded ameliorate only when the noise-reduction features didn't cut out our vox entirely). We thought the Besign'due south other features made upwards for this slight dip in sound quality, especially since the incoming audio yous hear during calls doesn't endure in the same way (although it does tend to be at a lower book than music).
It tin can exist tricky to effigy out just how long to hold the eye button downwards to actuate your phone'southward voice assistant without holding it so long that the Besign interprets information technology as your wanting to switch devices or pair a new one. We encountered similar problems with the other aux-in models nosotros tested, only the Besign was one of the easier ones to manage.
Our FM transmitter pick: GOgroove FlexSmart X2
Too nifty
An FM transmitter takes your phone's Bluetooth audio and transmits it over FM-radio frequencies to your automobile's radio tuner, and then it works with whatever stereo. After going hands-on with 7 of the highest-rated FM transmitters nosotros institute, we're confident that GOgroove's FlexSmart X2 is the best because it sounds as good as or better than the competition when tuned to the same stations. In fact, the FlexSmart X2 sounded meliorate than other FM transmitters, and it was comparable in sound quality to our aux-in selection. (To get such clarity, however, yous need a clear FM frequency—something that isn't always bachelor, especially in urban areas, where the FM dial is crowded with stations.)
The FlexSmart'southward FM transmitter performed relatively well in the strength and clarity of its indicate when compared with an aux-in transmitter or a native Bluetooth arrangement. It streamed music with practically no interference, providing the all-time audio fidelity of whatsoever of the FM units we tested—near equally skilful as a direct aux-in connection, with a slightly stronger midrange and slightly less focus on the highs. This surprised us, considering the ordinarily poor quality of FM transmitters. As long equally you find a good, clear frequency, you lot'll be impressed with the results.
Voicemails we left using the FlexSmart X2 sounded better than those recorded using other FM transmitters in both our windows-down and windows-upward tests. That's not to say that outgoing sound was perfect or even great—after all, sound transferred through a phone, and then over Bluetooth, and so over radio waves is leap to lose fidelity—but the X2 was the clear winner out of all the FM transmitters we tested. We also like that the X2 has multipoint pairing (so you tin can pair two phones at once), an aux-in jack for employ with non-Bluetooth devices, and an arguably nicer overall design—information technology looks more sleek and more pleasant than other models we tested, some of which wait clunky or intrusive in your motorcar.
The FlexSmart'due south three½-inch-long base, which plugs into your motorcar's accessory-power outlet, hosts a 4-inch-long, flexible gooseneck; the unit'south command module is at the other finish. This module has runway-control and play-and-pause buttons, buttons for answering and disconnecting calls, a punch for tuning and adjusting volume, a screen that displays the electric current manual frequency, an aux-in port, and a 1-amp USB port for charging your phone.
With the FlexSmart X2, each "notch" of the tuning dial moves the broadcast frequency (station) up or downwards one decimal number (for example, from 97.iv to 97.five), rather than the more common approach of browsing odd-numbered frequencies; however, it doesn't take long to get to a detail frequency.
Although the X2 has an motorcar-browse feature that claims to automatically find the all-time (read: clearest) FM frequency for transmission in your area, we found, after extensive real-world testing, that it's better to exist able to manually tune. The auto-scan feature might hit on a good, open frequency, but in our testing it was just as likely non to. In fact, it picked a handful of even-numbered stations (98.ii, for example) that aren't even accessible in the U.s.. Ultimately, we preferred the X2 model's granular, easily attainable command over models that have only auto-browse.
Our speakerphone option: Avantree CK11 Wireless Handsfree Visor Automobile Kit
Besides bang-up
If your primary employ for in-car Bluetooth is making and taking phone calls, a dedicated speakerphone offers better voice quality than aux-in kits or FM transmitters do. Later testing three height-rated models, we recommend the Avantree CK11 Wireless Handsfree Visor Automobile Kit. It'southward the simplest to employ while driving, thanks to straightforward controls that come the closest to feeling similar a native Bluetooth setup. It pairs speedily and easily with your phone, and the CK11 delivers clear, crisp audio through its congenital-in speaker, all at a astounding price. Although it wasn't the loudest, fullest-sounding, or fanciest-looking model that we tested, information technology still offered the best combination of features, usability, and sound quality at a great price.
In our voicemail tests, the Avantree CK11 produced loud, clear, intelligible sound whether the automobile was sitting yet or driving down the freeway. We didn't notice whatever echo, distortion, or interference, even with the windows cracked. When nosotros were talking on the telephone or using our phone's voice assistant, audio came through loud and clear on the CK11's single, 2-watt speaker. Our only telephone call-related complaint is how quickly this model announces the proper name of an incoming caller: in one case fast, before jumping to the ringtone audio, so yous're not prepared to process the words you're hearing. But this is a minor issue.
The Avantree CK11 slides onto your car visor with an attached clip, and information technology has only iii controls to worry virtually: an on/off switch; a mute button; and a book knob that doubles equally a multifunction button to activate Siri or Google Assistant, or to end a call in progress. By contrast, the other speakerphones nosotros tested include a range of unnecessary built-in voice commands, such as one that requires you to say "Phone commands" before really accessing the voice command capabilities of Siri or Google Banana.
The Avantree'south rechargeable battery is rated for twenty hours of talk time or 600 hours of standby time. If you leave the Avantree switched to "on" when you leave the automobile, it volition automatically shut down about 10 minutes afterwards you exit Bluetooth range with your telephone; information technology will and so turn back on as soon as you return and open up the motorcar door, thanks to a built-in motility sensor. This allows for a swift, hands-complimentary reconnection every time, while preserving battery life. And when the fourth dimension does come up to recharge, the Avantree includes both a USB cable and an in-car adapter, so you don't cease up stranded on the route with a drained device.
What to do if you accept a whiny audio cable
If you're hearing a whine with the sound cable plugged into your car's aux-in jack, as nosotros have with some units, this is likely due to radio-frequency interference from your car, or fifty-fifty your USB charger. A ground-loop noise isolator should help eliminate the buzzing. (Some of the aux-in kits we tested, including the Besign BK01 and the Mpow three in i Bluetooth Receiver for Car, include an isolator in the box.) But be enlightened that there can be trade-offs. When we tried ane with our previous elevation pick, the discontinued iClever Himbox HB01, it really decreased the overall volume and bass response, and left a slight baloney buzzing over the audio; we found some Amazon reviewers who'd had a like experience. This might not be the case with every isolator cable on the marketplace, merely given the take chances of a loss of audio quality, a high-pitched background whine could be a off-white trade-off.
The competition
Aux-in kits
Our previous pinnacle pick, the discontinued iClever Himbox HB01, produced even better phonation-call and music quality than the Besign BK01. And we yet recollect it's a great choice if you can find it in stock.
The Mpow 3 in 1 Bluetooth Receiver for Car has a similar design to the Besign BK01, merely the Mpow'due south audio is noticeably grainier, and you have to push the centre multifunction button to restart your music after a telephone call. The included ground-loop isolator improves the sound quality somewhat by cutting back on the interfering frequencies, only the Mpow all the same loses more allegiance than we'd prefer, sounding more similar a radio on a small, blown-out speaker.
Nosotros liked the Roav past Anker Bluetooth Receiver, and at get-go glance its low price makes it seem like a steal. However, it doesn't include a 12 V USB car charger, and buying your own brings the Roav's price in line with the Besign BK01'due south. The Roav's audio fidelity is as well slightly worse (and quieter) than what you go with the Besign, although the Roav's phone quality is a niggling amend. Y'all also can't trigger your phone's congenital-in voice assistant or skip tracks while listening to music or podcasts, which makes the whole experience rather limited.
We besides liked the Anker Soundsync A3352, which had the next-best music quality to the Besign BK01. But its biggest entreatment can also be its biggest flaw: The Anker Soundsync is a modest widget that plugs direct into your aux-in jack. With no cable, yous're express on where y'all tin position the controls on the dashboard. This blueprint could be a fine selection if your aux-in jack is high on the dashboard. Only it was a major trouble in our examination car, where the aux-in jack was located toward the bottom of the console. There, the microphone was barely able to pick up our vocalization, and nosotros had to blindly grope effectually to find the button that changes the vocal. The A3352 also runs on a rechargeable battery, instead of a plug, and it doesn't come with its ain charging adapter.
The Taotronics TT-BR04 is the only model we tested that tin be mounted on the car vents, rather than being attached to the dashboard with an agglutinative pad. This makes it easier to reposition, if necessary, or to movement between vehicles. The TT-BR04 was too the merely model with an on-off switch; we're not clear on why information technology has one, since this model powers off when you plow the car off, merely if y'all want that option, and then, hey, information technology's there. The sound was decent overall, with slightly better phone quality than the Besign BK01's and slightly worse audio for music and podcasts.
Kinivo's BTC450 offers phone-call sound quality reminiscent of talking with your friends on walkie-talkies in the woods during childhood. We assume most people don't want this, and, even if you do, it's definitely non worth paying more than you would for the Besign BK01, just to have a compact, distorted telephone call.
The GOgroove SmartMini Aux was a previous pinnacle pick because information technology has nifty call and sound quality and a congenital-in bombardment. Instead of a round fundamental unit that attaches to your dash, information technology consists of a small dongle that you can either plug directly into the aux input (if that input is close enough to the driver'due south side of the car) or mount on a small Velcro pedestal, which you can and then attach anywhere on the dash. However, the single-button interface can be a bit disruptive, and although its bombardment life is decent (up to half-dozen hours on a unmarried charge, according to the manufacturer), yous must provide your ain auto charger, which adds to the overall price.
SoundBot'southward SB360 lacks a few cardinal features—for example, it doesn't accept a hardware push button that can trigger Siri or Google Assistant, and it doesn't support multiple paired devices—and its audio quality earned tepid reviews from our testing panel. Nosotros do similar the charger it comes with, which provides ane 2.4-amp port, i 2.0-amp port, and a 1.0-amp port. Only the charger isn't enough to brand upwardly for this model's the poor sound quality and missing features.
FM transmitters
The Nulaxy KM18 FM Transmitter is similar to our peak choice, with a bendable gooseneck and an LCD brandish. The audio quality both for phone calls and music or podcasts is slightly worse but still serviceable. Unlike the GOgroove, the Nulaxy also has a slot for playing music directly from an optional SD card. (The LCD screen tin brandish vocal information for the SD card, although non for telephone playback.). Nonetheless, you can't access your phone's congenital-in voice assistant from the Nulaxy'south controls.
The Roav past Anker SmartCharge F2 Car Kit plugs directly into your motorcar's 12 5 ability outlet, without a dissever mic positioned closer to your face. So fifty-fifty though its voice quality is surprisingly good, that audio is noticeably quieter than that of other models we tested. The SmartCharge likewise doesn't offer you a way to brand outgoing calls without having to handle your phone. Information technology works well enough equally an FM transmitter for music and podcasts, but non quite as well as our pick, the GOgroove. The optional Roav app volition supposedly help you locate your car in a large parking lot, if that's something you need. (We didn't test this feature, because fifty-fifty if information technology worked well, it wouldn't pb u.s. to option the SmartCharge over the GOgroove.)
We previously recommended GOgroove's FlexSmart X3, a newer version of our summit FM selection. The base, which plugs into your automobile's accompaniment-power outlet, hosts a long, flexible arm, similar our pick. But the FlexSmart X3 didn't perform besides every bit the FlexSmart X2. CNET's Antuan Goodwin also reviewed this model and awarded it only ii½ stars (out of five), citing its poor automobile-scanning and a loftier-pitched alternator whine (though we didn't hear that in our tests).
Equally its name suggests, the GOgroove FlexSmart X3 Mini is a slimmed-downwards version of the FlexSmart X3. Instead of a long, flexible arm connecting its control pod and display to its charger plug, it has a short, rigid-plastic arm. Even so, our unit of measurement's automatic tuning feature stopped just on frequencies that ended in even-numbered tenths (for example, 90.2); since all Usa radio frequencies have odd-numbered tenths, this is obviously a bug. Amazon reviews indicate that we're non the only ones to feel this upshot with the X3 Mini.
Speakerphones
The Jabra Freeway has an FM transmitter, native voice commands, move sensors, and good audio quality, thanks to its large congenital-in speaker. The trade-off is its size: At iii.8 inches long and 5 inches wide, the Freeway is too big to easily fit on a car's visor. All the same despite its size, the Freeway lacks dedicated music-playback controls, instead relying solely on voice commands (such as "play," "cease," or "next track"). And when it's using the FM transmitter, instead of playing phone-call audio through its own speaker, the State highway sends that audio to your car stereo, resulting in a loss of quality. (We noticed similar quality loss while playing music.) Virtually annoyingly, the Freeway'due south vocalisation-command treatment is very clunky, and you must use information technology even to admission your telephone's own voice banana: Yous have to push a button on the speaker and say "phone commands" before you can admission Siri or Google Assistant. Nosotros establish this extra step annoying, too equally distracting while driving.
The more affordable Jabra Bout suffered from the same telephone-command frustrations every bit the Freeway, and though the Bout's telephone-call quality was remarkably proficient—better than fifty-fifty our top pick's—that better phone call quality wasn't enough to justify the Bout's higher toll, especially since it's harder to make and take calls on the route, considering of this model'southward clunky controls and voice commands.
We skipped over any speakerphone that didn't take a built-in FM transmitter, including the SuperTooth Hard disk drive Vocalism, the SuperTooth Buddy, and the Jabra Drive. Even though we generally aren't impressed past FM transmitters, we remember (given the limitations of a speakerphone's modest internal speakers) that it'southward essential to have the choice to play audio through your automobile'due south speakers.
