Pros: Clear sound quality, Noise Cancelling, Music doesn't die out if there's no battery, Price
Cons: Head hurts from long use
Overall they have good audio quality, the highs and mids are pretty defined and offer good sound as for comfort the foam on the cups have a memory effect so they get more comfortable the more you wear them but they're pretty tight on your head not recommended for long listening.
Noise Cancellation: They do a good job of cancelling. Blocking out a good amount of noise in noisy places (restaurant etc.) the pads also give off a good amount of isolation on their own.
