Syncwire Bluetooth 5.4 Aux Car Adapter [Large Mic&Noise Cancellation] Bluetooth 3.5mm Receiver for Car with Coiled Cable [Light Switch][Hands-Free Call] [HiFi Deep Bass] Plug-and-Play for Stereo Audio

Connects immediately when starting car. Good sound quality. Buttons work well. Mic is average for the price.

I am very impressed by smooth function, and the sound quality. My 2008 bmw original stereo sounds great. I can plug both the audio to aux and the power to USB in my console, with just the dongle out near shifter. It works as intended, logically. Once paired,it attaches automatically, with a cute spoken confirmation.When I use it, I have volume on phone up (I use the head unit to adjust) and don't use the bass option on the device. The signal is very flat, all frequencies reproduced equally, with no distortion. Even vocals were excellent. My car never sounded so good!(Before this, I tried a wireless device that broadcast to fm. Horrible sound, just awful.)Get this, you'll be happy.

I have used this for 1 day, about 3 hours so far. Installed in a 2011 E350. Because I didn't look at the reviews, I thought it would be much larger, but it fits conveniently in some dead space beneath the fan speed control. I like that there are buttons for pause, volume and phone control, but I wonder if they will retain their nice tactile press. I made a phone call today just to test out the mic and feedback. I got no complaints on a 20 minute call with the boss, but I was in traffic nearly stopped, so I'm not sure yet how it will function with road noise.What I don't like that I have seen others discuss is how the power cord runs with the audio cord. I think having a "squiggly" audio cord and a separate straight, maybe braided USB A or USB C cord would be nice. Not sure what appropriate cord lengths should be.I know that everything has rainbow lights on it now, and I don't hate it, but it would be nice to have a solid red option (red is softest for night driving)....but so far, for my needs, this seems like a great solution. This is for a work van that I don't own. The van has a stock radio that included a 3.5mm input. I bought what I thought was the least expensive solution that fit my needs. Compared to the FM radio, I can't pick out anything about the audio quality, but it wasn't great to begin with. Phone call was clear with no feedback or echo.

Great way to hook up a older car (2010 Camry) to my new Bluetooth only S24+. The sound is excellent especially with my S24+ Dolby Atmos turn on . Depending on your cable run to 3.5 mm audio in jack, 3.5mm a female to female cable adaptor could be useful accessory to buy. Set up took about 2 minutes . Plug the USB A into open slot on my 12 volt phone charger to power the Bluetooth adaptor. Then for my Camry I already had a 3ft 3.5 mm male to male end cable (my old S10 had a 3.5mm jack) next I connect both male ends of the 3.5 mm cables in small 4" female to female ended cable adaptor and made sure both male 3.5 jacks were securely fitted into the gender change adaptor. The push the power on button on the Syncwire Bluetooth 5.4 Aux Car Adapter open the Bluetooth menu on my S24+ and it instantly connected with the adaptor. Know I can listen to YouTube live streams or my favorite Pandora channels with no problems . Another big plus is with the Syncwire Bluetooth 5.4 Aux Car Adapter being power by USB there no problems with recharging the battery or it going dead on a full day drive . This Syncwire Bluetooth 5.4 Aux Car Adapter is a great steal a $20.00 . A+++ grade so far.

It works... does everything its supposed to..The device looked and felt fantastic.Initial Pairing was simple and auto-reconnect was fast.However the audio from music was just terrible.Flat and dead in the mid range.. Bass was flat and sounded completely off.Couldn't fix it with EQ settings.Bass-Boost helped and fixed some of the issues.. but it actually made the music too bass heavy and muddied the highs and mids...Overall, it just wasnt good enough and not something I wanted to live with daily... would rather just plug my phone in for better quality.Returned the device. Bought the Tunai Firefly.... Its much better. Sounds just about as good as plugging directly into the phone.

Works as it should. Sounds amazing... the bass boost really makes it a must have! Great purchase!

Boy howdy then this is for you. Probably the worst sound quality I've heard over Bluetooth in my life.The only redeeming quality on this device is the microphone, people have had no problem hearing me, but I can't hear them unless the volume is all the way up, and you better be fast to turn it down after they hang up or it'll be full volume music right after.Absolutely not made for anything but style, because it looks good but performance is a miss. Connected easily, easy to navigate, but all that is for naught if the music doesn't sound good in my opinion, it literally sounds like I put my speaker in a fish bowl.

Amazing product! The adhesive is fantastic and sleek look is perfect!
