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.

I like the design of this product, as I was looking for a small noise cancelling earphones, so this fits the bill. It is a quality product, albeit a bit on the expensive side. The earphone are good in use, the only slight annoying feature is the location of the battery. Should have an option to detach the earphones from the battery pack when not using the noise cancelling function.
