One of the speakers stopped working 4 months after purchase, then the MD2 were sent back to Italy and got repaired. After 3 weeks that speaker stopped working again. Could be the soldering issue, or my bad luck. They have worked for around 300 hours, and were stored in the case each time after use.   Finally I returned the headphones and got a partial refund, since the depreciation and their postage cost have been deducted.   Despite such issues, MD2 are a nice pair of headphones to enjoy the music for some people. They are definitely coloured...
