I have had two pair of these headphones, both broke within a few months. The first pair failed in the connection between the two phones. The wiring broke. As a result one channel of the sound was lost. I suspect that the failure was caused by the flexing of the wires when the headphones were folded. The second pair broke its wiring at the point of entry into the headphone. In that case both channels of sound were lost. The price seemed good at the time of purchase, but the flimsy wiring resulted in premature failure.
