Syncwire Bluetooth 5.4 FM Transmitter for Car, 38W PD&QC3.0 Dual USB Charging Bluetooth Car Adapter Microphone & Bass Sound MP3 Music Player FM Kit with Hands-Free Calling

I had very low expectations for an FM transmitter. They have all had static or FM interference as you drive around. This one did not! Connected easily the first time and every time. Music was clear and static free. Even worked pretty well for speakerphone calls. You will want to unplug it from power when you leave the car so it will drop the bluetooth connection.

I bought this for my 2008 Miata which has the Bose system with a multi-cd system that no longer works. I actually got the Syncwire Bluetooth Transmitter as a stop gap while I shopped for a new car stereo unit. To my surprise, this Syncwire Transmitter works great! Much better than I expected! I’m thinking now of just keeping the Bose unit and using the Syncwire Transmitter and using my iPhone for the music source. Great value, no connectivity issues, music sounds great.

Very easy to use. Don't expect sound quality to be the same as a radio would produce, but it's pretty damn good considering! Happy with my purchase.

Happy with quality and performance. Easy set-up

It works well. Syncwire is a brand we trust, because our first one is still going strong, so when we got a second car, we had no indecision about which Bluetooth transmitter to get.

Works great ! Sounds is very clear. The only annoying thing is the bright blue flash that is produces while its on. Its very distracting and you have to turn it off manually every time you turn the car on

Setup was incredibly simple. Just find and open unused FM frequency on your radio, save it on the radio so it has a preset button like the rest of the stations, and then twist the dial on the transmitter to the same channel and you are set. Pair the bluetooth, and you can play music or whatever from your phone. and the sound is great sounds just like the other channels on the radio. My only (small) gripe, as others have noted, is that as you look at the picture, it is best to have to have the buttons, especially the call answer button, on top so you can see it. But if you do that, the radio channel reads upside down. Not a big deal since once you set that channel, you won't be changing it, but it's just odd seeing the upside down FM frequency. It would also be nice to have an on-off button as well, since once you plug it into the lighter, it's on all the time. You have pull it out a little to shut it off. Some have mentioned the blue light is annoying. It is useful in one regard...it reminds me to unplug it when I get home. Edit: BTW, I use FM frequency 87.9, which is on the low end and is not licensed to be used by an commercial radio station in the US.

Works flawlessly for my audiobooks and music. While the sound quality is not as good as phone-to-bluetooth, it is as good as any FM station, and I am not willing to replace my car stereo. The phone-call function is no go. The mic on the device can't overcome the cabin sound in my 2008 Forester. It works. But terrible. I just switch to my earbuds for calls. This is the only reason I did not give it 5 stars. If it were just a Bluetooth broadcaster without attempting to do what it can not do well (phone calls), it would have received 5 stars. IMO, they should just remove the call-mic function.

It is sturdy and well made. This works great for getting your vast music library off your mobile phone onto your cars sound system though there is some audio quality lose due to transmitting the music from the phone via bluetooth and then converting it to an fm transmission. I would recommend using the bass boost to help counteract the audio loss and the sound of the road. It happily charges two devices fast via the usb sockets so no excuse with having your phone battery run flat. It has controls for adjusting volume, pause/play and changing tracks forward and back. It also has functions to work as a handsfree device to answer the phone but since I dont use the phone at all while driving I have not tested this. If I had any criticism for this it would have to be: 1. It has an always on pulsating light which is dim during the day but depending on the car maybe distracting to the driver while driving at night. 2. it should switch controls for volume and track forward./back. Currently you can just twiddle the dial and it changes the volume but if you press the play button twice and then twiddle the dial it will change track. This is pointless as realistically speaking you would use the big volume knob on the radio to change the volume after setting the FM transmitters volume to a balanced volume with the in car radio and cd player. This would make it alot easier to play and change tracks while driving as double pressing the play button is destracting. It doesn't really bother me as I remove all songs from the playlist before I set off. All in all I think its a great bit of kit with a few shortcomings but well worth the purchase.

Been usinging it for months and its working great. Good quality, clear sound

This little FM/Bluetooth is perfect if your car isn’t from the last decade. The audio is clear and signal hasn’t dropped yet; even on a channel with some interference. The tactile spin dial is very nice to use, although once set you’ll rarely have to use it but it’s nice not having to press a bazillion times to find a channel that’s clear. Feels fairly well made, bright clear LED is with a light right that pulses to the music, cool I guess. The USB 4.0 & USB C ports are very handy to get things charged too. Displays how many volts your car battery has too which is handy if your car isn’t starting, you could diagnose a dead battery immediately.

Works fine, connects fast, but just don't expect great sound as if connected to a direct source. No fault of the unit, just the way it is.For 30 bucks it is worth it.

It's simple and straightforward, works as advertised. It feels well built and sturdy. It's a good size to just leave in the dash all the time, doesn't get in the way or distract. I like the rotating ring for FM frequency selection and volume. The colour pulses to the music, and can be turned off. It remembers the last FM frequency you tuned it to, and displays it on startup. The USB-A and USB-C power ports are a nice addition, but I haven't tested them yet. It has no amplifier, so the onboard volume control is really just a volume reduction. I just leave it at max and use the car stereo volume. Not so great: No buttons to skip to next/previous song. I guess I can learn to live with that. The "extra bass" button works but resulting sound is muffled and muddy. Don't bother. The hands-free phone connectivity works, but the mic is very weak. Callers can barely hear me in the car with the engine off. It's unusable when driving, especially on the highway. There's more difference than I expected between low and high FM frequencies. Empty spots in the 88-90 Mhz range sound noticeably worse than empty spots in the 104-107 Mhz range, for same car / same phone / same song. Radio stations at the low end of FM come in clear, this device from a foot away - not so much. And finally, it's quieter than I expected. With transmitter volume and phone volume at max (and onscreen "hearing damage" warnings), I have to turn the car stereo up much more than I would for a radio station. Strong local station might need 40-50% car stereo volume at highway speed, but this transmitter needs 75% or more to get the same actual volume. Same phone in our other vehicle with native BT doesn't have this volume difference.
