Pros Sound profile is warm; bass reproduction is impressive in on-ear drivers of this size. They are quite comfortable; ear fatigue is virtually nil even after several hours of use. Extremely faithful reproduction of source material.
Cons Construction is slightly flimsy. These 'phones will not suffer even medium abuse gladly. Straight plug virtually guarantees cord short eventually. L-plug would have been better. Could be a little louder.
Summary At low to medium volumes, the ability to hear adjacent noises is excellent. These are great for situations that require sonic awareness of surroundings such as bike messaging, waiting rooms, etc. Quality for for price makes them a superb value. Smart phone control (mic, answer/end call, volume adjustment, play/pause, next/last track) is really just the icing on a cake that already tastes pretty damn good. I love these headphones.
