These will not block out your co-workers noise but they do have excellent sound and comfort

These headphones had amazing sound quality and comfort but the passive sound isolation was mediocre at best

Comfort may not be the highest priority for most purveyors of sound, but I assure you, after a couple of hours of listening, they may change their mind

They may seem a bit gaudy for some, but the comfort and sound is really worth it with this headphones

the padding only rests against the side of my head (with room to move, as well)Durability / comfort

The comfort of these headphones is unrivaled

Comfort for my John Merrick head, juicy bass, clean highs and present mids.

Fantastic comfort and sound quality

Last but not least the comfort on these is just GREAT

Super durable can, Superior sound quality, and Superior Comfort = 5 big stars!

These are part of a breed of warm sounding cans (Beyer / Ultrasone) that will make certain genres sound great!Comfort: The best of any cans I've owned

Comfort is outstanding with a snug fit over my head

10 fold superior quality and comfort to the logitech G35, and many other apt competitors

Also when looking inside the headphones where my ears have been getting treated to beautiful sound and comfort over the years... well, it didn't look pretty

Superior comfort

The passive noise rejection and comfort are good enough that I occasionally wear them without music playing
