Query: Very disappointing.

I returned these headphones as soon as I tried them. They have absolutely no noise-cancellation ability, they're not very comfortable and they're just clunky and a mess. I have tried and owned other noise-cancelling headphones for about the same price and they may not be the best but they do work, these do not. I only gave it 2 stars because I love the concept, now if someone would make some that actually work.
