The function that made me choose this was translated bluetooth. From this point of view I am satisfied, the implementation is simple and satisfying. However the sound quality is disappointing, especially at low volume. Indeed the upper midrange and treble are too recessed and the sound spectrum is pulled low.

Conclusion: correct product for watching TV medium or high volume, but disappointing for a low vdune use and / or musical
