I do think some of their headphones are best in class - Not the greatest value for money though. Their QC line have the best noise cancelling, and if that's the most important criteria they are the ones I recommend to people. (Personally I use Sennheiser for my ANC cans as the sound is better and noise cancelling is not too far off).
Their sports in-ears are great also - I've never found any in-ear headphone that beats the MIE2 in comfort and not falling out, and the sound isn't bad either.
