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.

I have been using these earphones for over a month now. So far they have been great! Amazing quality audio and sound cancellation. However, the sound cancelling doesn't work properly when travelling on vehicles with high turbulence (e.g. Buses), as this affects the mics. on the sides of the earbuds, thus affecting the cancellation. This distorts the audio and can make it quite unpleasant to listen to. Although overall, apart from Buses, everywhere else the cancellation is great and works perfectly. Great Earphones, highly recommended!
