I have a very high-end audio amplifier but not equipped with Bluetooth or USB connection to read my dematerialized music. So I bought this little box (not so small that matter) and I connected with the digital coaxial terminal (indispensable to maintain sound quality). Recognition of the case by my tablet automatically. The mini blue LED will light. This is in contrast to discrete ultra Logitech housing. I run my playlist and my speakers deliver a sound close the original CD. This is PERFECT for home listening in everyday life. I have no signal loss despite phones, TV, or oven in working order ...
In summary, I had big doubts about the audio quality of this camera under my Hi-Fi system. But listening is still really good if you take the trouble to choose music tracks not compressed too of course!
