Query: Poor Comfort

There is really no way to tell from the picture but these headphones are too small for human ears. Neither fits on or over the ears. They are certainly tall enough but not wide enough. No humans have this ear profile. The sound canceling circuit is OK but should be more powerful and the the sound deadening properties of the materials used in construction are nil. Could be OK for people using occasionally on short occasions.
