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.

Good and easy to use
Works great, easy connection to phone and car. Allows my car to not have ignition on unlike 12v fm adaptors. Good size, would be nice if it had some sort of vent mount or sticky back. Good sound quality and volume control, would rather it was double press instead of long hold to do multi function buttons as skipping tracks and driving may be a bit challenging. Small and lightweight

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.

Very good bluetooth connector
I got this to use in my car as i don't have bluetooth. Its very good for the price, works perfect have had no issues, sound quality is perfect. Easy to set up. Battery last very long. When its connected to your iPhone you can see the battery usage of the bluetooth connector which is good. I would defiantly recommend.

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.

Get connected...
Better than I thought it was going to be, good quality sound, simple to use, connects easily, no interference, does the job well and at a decent price.

I got it to pair to my phone to run my old corded iems, it costs slightly more than an aux-usbc dongle but not much more and it frees up my phone for charging or just using without cables attached to it. The AptX is really good, which means the corded iems sound as good as plugged in and actually better than most expensive BT headphones from years ago running on older standards. Button controls work well, the volume buttons double as skip track and back so sometimes I accidentally SKIP when I'm trying to VOL up too quick but it's not often.. I've not had anyone complain about the mic on it when taking calls but ypu do have to take it out of your pocket. Battery lasts a lot longer than any wireless IEMS out there, stays connected well. Good value IMO, hopefully lasts as well

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.
