Just after first listening to reception, I was pretty disappointed with the sound rendering. The sound seemed muffled and withdrawn.
After several hours of listening (the time that the membranes rodent?) ... Frankly I love them.
The sound is actually open enough, and the bass is for a pregnant ouf of this size (rather than on EU Boom!)
My big blow bluetooth speaker heart goes everywhere after testing: EU Boom, Belkin Fusive Anker A7908 JBL Charge, JBL Flip, Jabra Stolemate ...
With lightning offers, I came across a quality / price ratio ...

Its really nice
Acute not garish
The low indeed present (on some tracks that severe kick)
A monstrous autonomy (I must be easy to 15 or 20h average volume listening)

Lacks a bit of power at maximum volume
A sometimes tend to saturate at maximum volume
