I like the sound reproduction with this one. I did not notice any particular saturation, even at the radio (my phone is wifi, although it helps, I agree).
The enclosure offers us the opportunity to answer the phone. It is not the function that I use mainly: it is a sacred time when I'm in my bathroom, not at that moment that I love chatting.
It is splash proof, but is not submersible. That is its biggest flaw. I do not trust her attachment system, it would have been on be completely airtight if it happened that it drops into the bath water ... At this level, it could be renamed " AQUAPLOUF! "
It is fixed using a large suction cup: I who mosaic wall ... it's complicated to set. So it's in my shower gel support. I can not put it elsewhere. I would have liked a different attachment (for example as a hook).
The battery is correct. The charging time is not excessive. For its duration, depending on the volume is used.
In conclusion, this small chamber filled quite the function for which it is intended without being waterproof.
