Perfect bluetooth device
I was looking for a Bluetooth device which will not only work with my 13 year old Sony sound system but also will give me a very good sound output. I must say that I got what I was looking for.

Good if you want to use for wireless speaker but not for wirless earphones
Product is very in quality, sound and its compact. Only problem i faced is with mic. When i use my earphones which has already mic, it still use the built in mic in the device and the voice is not that good

Annoying prompts
Decent receiver, but the connect and disconnected voices are loud and annoying. They are slightly louder then the music itself to my ears, and annoying AF.

Works perfectly with old cars even
It works and there is no noise in output, which is quite nice.

Battery backup and connectivity
Battery backup is not great If you switch it off everytime after use, it gives connectivity problem.... So i started leaving it on and switching off my phone bt and now that problem is gone. But again, it drains the battery faster

Works as specified. Sounds a little better than wired connection. Recommended.
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.

Hızlı bağlantı,kaliteli ürün
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.

this works great for headphones, even works with car that have 2.5mm plug
pretty good range on these before they cut out (if you have to run up the stairs). easy to recharge, works well, connects well, can't tell difference in audio quality. of course you can interrupt the signal because its going over bluetooth vs wired connection, but it is great for using your favourite headphones when you're working in kitchen and just put it in your pocket.
