These are seriously the best pair of cans I've ever gotten my hands on. They sound good, they were not incredibly expensive, they cancel noise without the "pressure" on the hears of active noise cancelling sets, and they are "over the ear" 'phones. If you wear glasses, I recommend the over-the-ear ones because they don't smash your ear against the arm of your glasses while in use.Pros: Great sound, noise cancelling, relatively inexpensive.Cons: Don't sound quite as good as my Logitech Z-2300 speakers, large.
