SYNCWIRE 5.1 Bluetooth Car Adapter FM Transmitter - 38W PD & QC 3.0 Fast Car Charger Bluetooth FM Wireless Radio Adapter Car Kit, Hands-Free Calling, Support USB Disk

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.

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

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.

Brilliant blue tooth transmitter (and with an infinitely better Bluetooth quality than my much older one from a few years ago with absolutely no engine interference) and crystal clear audio. The optional Extra Bass setting may be good for a car with a huge subwoofer but I find it just too much and just use the default setting (i.e. "off") and it sounds awesome !!! Love the rotary knob to adjust the volume without having to touch the stereo - very convenient. Phone Calls and Apple Maps spoken directions come through perfectly too. I bought two (one for me and one for my son). Highly Recommended !!!!
