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

Bought this for my old Accord and it was a lifesaver!! My phone auto connected every time and it was super easy to set up and continue to use for 2ish years!! Would definitely recommend, music was clear and had good quality sound. On long road trips when radio stations switch around you might have to adjust it, otherwise perfect for local commutes!

Works great if you don’t have Bluetooth in your car

I’ve been looking to replace and older Bluetooth transmitters (2020 Vicsing) that I had for years previously. This was my 7th potential replacement that I’ve tried. Of all of them, this was the best so far but, it still not exactly what I need. PROS: The sound quality is great. The music playback is excellent with the bass booster. The volume is appropriately loud enough that the music sounds like it’s playing directly from my car’s audio. I didn’t experience static or noise interference. Call quality is also great. The noise cancellation feature is really effective in this device. People hear me loud and clear and it doesn’t pick up car/road noise. The microphone picks up clear as if I’m using the speakerphone on my iPhone. On many of the other devices that I have tried, I found that I either had really great music quality or great call quality but not both. One would have The bass boost function, but lack the noise, cancellation feature for calls or vice versa. It has an usb-b and an usb-c port which is great for charging. My phone charges relatively quickly. Despite missing some of the things I was previously accustomed to, I thought I had finally found the perfect replacement. BUT CONS: A minor con, which wasn’t a dealbreaker for me was the fact that it did not announce that Bluetooth was connected upon turning on my car. Instead, you get two beeps one to let you know that it’s on and two to let you know that it has connected to your phone. I was able to adjust to that. Another con is the playback, skip and reverse function. In order to do so with this device, you must click the call button twice and then turn the dial left to go back or right to skip forward. I have a 2006 Honda Accord where the cigarette lighter is in the console by the gearshift with a covered door on top. The cover naturally wants to close when there’s nothing in the cigarette lighter so unfortunately it rests on this device. It’s a pain to have to look down make sure I’m clicking the right Great button and then kinda holding the cover up so that I can turn the knob at the same time. This is especially annoying when you click the call button twice turn the lap right to skip and then decide you want to skip that song too. You have to then click the button again and turn the knob as opposed to being able to click. Keep turning the knob right. You can do that if you make your decision to skip within seconds of doing the previous skip otherwise you must start the process again. Other devices have a dedicated button to press or a joystick function to move ahead. It is not a great set up, but I could deal but another con made it impossible for me to overlook this drawback. That last con is - unlike other devices that will use Siri to announce who’s calling from my contact list, this device uses its default programming that I cannot override. It announces the call by saying the entire phone number (country code, area code and phone number) ALL OF THEM! So, you’re literally listening to over 10 digits being called out whenever a phone call comes through. I find this incredibly annoying. I would rather it not announce anything at all as if this is the only option. Imagine trying to listen to music and that breaks in and then you have to fumble with the button to accept the call. Declining the call was not easy for me so if I didn’t want to take the call I had to listen to the whole number so I wouldn’t be distracted while driving. This drawback in conjunction with the awkward skip playback feature makes it a dealbreaker for me. I will continue to look for devices that don’t have this these shortcomings , and also give me excellent audio quality like my old transmitter. I know it’s possible. Overall, it’s a decent transmitter if you don’t mind the awkwardness of having to use the skip feature and not being bothered by the annoying phone number announcement when calls come through. To find a device with both great call quality with noise cancellation AND good music playback with bass boost is really rare. Even devices that claim to have both, usually one feature suffers a bit more than the other. This device got it perfect. Unfortunately the cons just don’t work for me.

This is the one to get. I tried and returned several other blue tooth transmitters. It was the easiest to regularly use - just tune in the same frequency on the radio that you've selected on the transmitter. This model has the quietest background noise, so high fidelity is heard clearly without hiss. Tip: find the local FM frequency with no radio stations nearby on the channel number you've chosen, this will give less interference and better sound.

I have an old car so this was very needed. It works well. The Bluetooth sometimes disconnects if you pause the music. Also , i can’t use this while I’m on the phone. No one can hear me and i can’t hear them. So when i get a phone call, i have to disconnect it. It works very well for music over the radio though.

First thing I have to say about this FM transmitter is I really appreciate the sleek look it has. It is compact and doesn’t get in the way. I have seen other transmitters that are so bulky. It was easy to set up, and it connects to my phone very quick. The reason for the 3 stars was because there can be some feedback heard when you’re listening to things that require more volume, like a book or podcast. It works well for music, but there is no skip button on the transmitter. I have to go on my phone to skip the song. Other than that, it is a decent product. The price isn’t bad, and I appreciate the functionality of the device.

Works perfect with my calls but more I wanted it for to play my music off my phone. I love it 😍

Update 7/21/25: been using since May. Still love it! ~~~~~~~~~~~~~~~~~~ This is cool! I inherited my dad's 2001 GMC pickup truck. Of course no Bluetooth capacity, so I was looking for alternatives. This FM transmitter was very easy to set up and connect. I've only been using it a couple days, but it's great to get the better sound quality through the truck's speakers. You need to pay attention to whether or not it'll fit in your cigarette lighter plug in. I saw this on another review and some of the bigger square ones definitely wouldn't have worked. This is a little bigger than a regular cigarette lighter plug in charger. It's a little tight, but I can reach the buttons pretty easily. Don't need them often, mainly to answer calls. I'm not sure about the microphone. My SO said I wasn't loud, but he's 75 and hard of hearing so not sure that's a valid criticism. You can turn off the lights. It automatically reconnects when I turn the truck in. Hope it lasts. I love it! Worth the money. I can listen to my own music and audiobooks without ads. Yay!

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

Worked well and as advertised, easy to set up.

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 !!!!

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.
