I think these have a pretty serious design flaw. The buds are so heavy, they always fall out of my ear. In the end I returned them because my unit stopped charging. I had used them on a couple of flights. The annoying thing was that I would be listening to something and drifting off to sleep, then the earbuds would fall out.

After reading many disheartening reviews about the sound quality and noise isolation being poor I was surprised at how wrong they are. Obviously the sound quality isn't as good as normal earphones of the same price the sound quality is noticeably better than other earphones I have used before. I have used these earphones whilst studying in a noisy room and was shocked that I couldn't hear anything apart from music which was at a low volume, the noise isolation is so versatile because of the 3 different settings and this is probably its best feature

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.
