For the money these phones really are superb. You need to run them in to get their best performance and then they really start to sing with deep bass and clear sharp highs. The only minor criticism is they can distort a bit at high volume but then they are VERY loud so you probably only need them set at mid level.
6 Sets of ear buds ensure a good fit and give you a spare set in your size, plus the carry case, airplane adaptor and cleaning tool are nice extras. Ive tried them on a plane and the noise isolation is very good. These would be OK at £90 but at £40 they are brilliant value - buy a set and see for yourself, you wont be dissapointed.
