A Stereo headset that has not been abused but used in a normal manner and whose net break plastic frame at the height of the earpiece, I call it junk. This happens very rarely but for me once: disappointment. The quality is not at the rendezvous. Ordered 16 January 2012, delivered January 18, 2012 - Amazon always impeccable on delivery - and out of service February 20, 2012 it does not really fun. Is this an exception or these helmets they are extremely fragile and prone to such accidents?
