Bose QuietComfort 3

Pros: Comfortable. Good sound quality

Cons: Price, but that's a one-time thing

Summary: I bought these in the Seattle airport last week. Had plenty of time to try them out in comparison with the 2's and after two visits to the Bose booth, chose these. I might have rationalized saving $50 by buying the 2's but determined that these did a slightly better job of eliminating aircraft noise (the booth had an aircraft noise recording they played). Coupled with the lighter feel, additional Li-Ion battery for no extra charge, and slightly better noise cancellation, this was my choice at $349.
