Very good product
Would recommend. The charge lasts a long time and the sound quality is great. It’s easy to set up and connects automatically when turned on. You can also take calls like CarPlay. Overall very happy with it.

Excellent for 2018 Mini One
Purchased for my partner who has a 2018 Mini One. This works really well. Connects 99% of the time, just the odd occasion where it doesn’t. All it takes it a switch off and back on and you’re good to go.

Good quality audio, missing auto-turn-off feature
Overall a very good receiver, works a treat with the car. The quality of sound is much better than my previous solution which was an fm transmitter. The kit comes with a usb charging/power cable an aux to aux connector and aux to aux cable. Connecting to the phone is very easy. Very happy with it in the car, when plugged in, it automatically turns on when it receives power from the engine which is very useful. It is missing an auto turn off feature however when the engine is switched off and it is no longer charging.

Great for the price
Really easy to set up, holds its charge well. Pairs to other devices swimmingly and gives a good sound quality to music played. I haven't used it for calls and won't be likely to so cannot comment on that. Really handy that it shows the battery percentage from your phone so you don't have to wonder when you have to charge it up again

Decent quality, cheap BT Adapter
For £15, the sound quality and connection stability, which are the two things most important to me are virtually flawless. Connecting via an iPhone 13, I have been using the device for a number of months and my only main complaint is that the microphone for calls is pretty bad, I will expand on that, you have to be in a pretty much silent place in your car. So pulled over in a parking spot with your engine not running. It will work for receiving and making calls, just don’t expect great voice pickup from the built in mic. I didn’t plan on using it for calls anyway, just for streaming music from my phone to my car via the 3.5mm jack. For this, the device is excellent m, with great audio quality and no drop outs. This would be a 5 star review, but it loses a star for the poor quality microphone. Lastly, the battery is great though I have a 12 volt input connector right next to the 3.5mm input in my car, so I leave it permanently plugged in using a 12 volt to two usb adapter which you will need to power it or charge it in the car. If your car has usb, then you can use this, however I would imagine if you have a usb input on your car, you probably don’t need this bt transmitter in the first place, as most usb connectors on cars allow you to connect your phone and access your music that way, simply with plugging in a cable. Easy mode!

Great Sound, Poor Mic – Needs Frequent Charging
The audio quality is very good and the Bluetooth connection is stable and reliable, even over longer sessions. Unfortunately, the built-in microphone is disappointing — it picks up a lot of background noise and isn’t great for calls. Also, keep in mind that the unit has a built-in battery that needs regular charging, so it’s less convenient if you want a constant power setup. Good for music, but not ideal for hands-free use.

Great for music and connectivity
This device is amazing, super sound quality, lightweight and excellent connectivity. It has very good amplification too. I realized that it outclassed even the expensive headphone DAC despite of being wireless. I really appreciate and strongly recommend to try this device.

Works fine but lacking
Works well. Construction is plastic but feels solid. Main complaint would be the lack of inline audio control support (earphones with play/pause don’t work) and the annoying voice lines that play when it turns on/off/device yawns/wind blows/etc. Sound quality is fine. Can’t hear a significant difference between listening directly or listening through the adapter. There is an annoying quiet static that is audible during silence though. Lowest volume is more like 70% and ramps up very quick with no way to change it. Good overall but not a great fit for headphones or earphones as-is.

Great little unit, works really well. Allows me to stream music to the radio on my 2012 BMW.

It works as specified. Connection and pairing bluetooth between my iPhone and an old Panasonic mini-Hifi set went without any glitches (so far). I find the sound quality quite good as compared to a wired connection from my phone to the hifi audio port. The song continued to play when I bring the phone 3 - 4 metres away and behind a wall. The item was made in China. I do not know how long it will last, but so far so good. Item was delivered the next day after ordering and payment.

I thought of getting bluetooth speakers for my older car, but those are bulky and might get stolen. Connecting the phone with an aux cable is also cumbersome. So after comparing specs and reviews of several adapters, I went for this one and I have no regrets. When turning the adapter on it does say something like 'bluetooth connected' like described in other reviews, but its not as annoying and loud like in some bluetooth speakers. It's a soft gentile female voice. Unfortunately that feature can't be turned off. Pairing 2 phones was a breeze. Sound and volume are good. A call made with this gadget was fine, but I guess it depends on how close the adapter is. Taking calls with the adapter can be switched off in the phone settings. I like that the adapter has a couple of buttons, so you don't have to reach for the phone to change volume, skip to next track, or take calls, etc. Can't comment yet on the battery life. It's supposed to last for 17 hours. That's long enough for my needs, besides it's no effort to attach a USB cable. So overall, I'm happy with this little adapter.

2014 Model Polo aracımda kullanıyorum. Gayet hızlı bağlanıyor. Bağlantıda kesilme, kopma vs yok. Aux çıkışlı güzel bir bluetooth bağlantı cihazı almak isteyenler için tavsiye edilir.
