Solid Headphones, Step Shy of Bose

Bought a pair of these to try before dropping $300 on Bose. Overall they are very good headphones. Noise cancellation on par with Bose. Sound quality and comfort are a step down. I used them for a long plane trip (17 hours each way) and they were fine. I was a little more conscious of the fact that I had headphones on (vs. the Bose), but comfort was ok for 2 back to back 8 hour flights. I'd borrowed Bose from a friend and used on a similar flight prior to purchasing the Panasonic, so it was easy to do a head to head. For the money, a strong product. If you can easily afford the Bose, go that way.
