Bought this product three weeks ago, it works perfectly, but just one problem. It needs sony software to be at its best. This means some songs will simply just sound weird especially when they have a deep bass. Otherwise, they are awesome

I like this ear phone, the noise cancelling is perfect on you turn the switch on you will be in another world away from any noise around you. I highly recommend this ear phones.

The only snag is that the earpiece sticks out making sleep difficult on long haul flights, but this is a minor issue.
