Good quality bluetooth, however if i leave it plugged in it auto turns on when i have bluetooth on any of my devices and will try to auto take over sound and so i have to unplug it when not in use.
I don't use it very often but it's nice to have in those moments I want to play music from my phone to my stereo from around the house.Also, I noticed this adapter only needs 5v of power.
Good product, did not work for every surround sound system i have, but worked for the one I bought it for.
It will only pair with one unit at a time but it is quick and easy to do if you want to change to another phone or tablet.I have had this for months now without a single problem.
Very easy to use i used it on an analog stereo system wanted to play my music from my computer into my stereo system without having cables very happy that it worked highly recommend !!
When you disconnect it, it automatically reconnects in a few seconds, so the only way to turn it off is to either have echo "forget" the device which removes it or unplug the power cable from the bluetooth adapter.
So far it seems to work fine as far as volume and not dropping once connected but there needs to be a disconnect feature without having to have your phone "forget this device" and then have to fully re-pair when you want to use it again, or turn it on/off every time.
I hooked this to my sound system, and it caused a constant buzzing noise, and cut out like it was out of range, when my phone that was connected, was only six inches away.
Since it doesn't have an on/off switch, I will have to either unplug it or pair it every time I want to use it with my phone, which is what makes it highly annoying.
The 2 stars is because it is not what I bought it for and it is not clear on the website that it cannot be used without mains power.
