Already I had to return because the left diaphragm vibrate, not Decouter my music. a faith received new I could test it: - The sound is very powerful especially if your room and small - It is rather beautiful - The sound is good, even better with a Sub. ................................... For me the big problem is what breath all the time and on the second she received blows, I use to listen to music but also to my piano and by the time you do not play and breath and really annoying. these walls are also very sensitive to the mass problem, if your PC is connected to dimension it will blow and make noises of the hard drive or mouse, made attentions. I do not use my Bluetooth works well but quality remains good, but I feel that the breath is even worse ..
In the end I was returning for a refund, it's people are beautiful but too much of a problem dimension, and for that price I like is that when jachète is perfect. I do not really advice.
