As against the quality is not really there. Many of breath when there is no sound. When the music is strong enough we do not hear too much more but in the silence he returns.
I tried with several devices (Android, iPhone, iPod touch, PC, etc ...) it is the same result: the breath ... These same devices connected with bluetouth enclosure does not have this problem. So it is this receptor is involved.
I tried to move but no difference ...
Too bad.
I do not regret my purchase still, it helps out. But when I want to listen to music from my PC, I go through a HDMI cable !!!
