Sennheiser PXC 300 (headphones)

Pros: Very easy to travel with, great noise canceling, fantasitic sound quality

Cons: No real cons here... they don't block out screaming kids

Summary: I have owned this headset for 6 months now, and 30,000 airline miles! These are by far the best sounding headset I have ever had, and the noise cancelling is fantastic!!! I love puting this on a friend, then asking how they sound... they are really impressed, then I flick the NC switch and watch their expression!! WOW, is all they say. I use rechargable batteries and they last for weeks. They are strong, light weight. You can't go wrong with the company that invented noise canceling technology. Sennheiser created this technology for pilots. Back to the sound quality, full range, great highs and base, what more can I say... best headphones on the planet (even off the planet when you are in an airplane). One other note, I was sitting next to a guy with his $300 Bose NC phones, I asked him if we could swap for a minute, and he didn't want to give me mine back (I couldn't wait to give his back to him). Well needless to say you can't get anything better than these. BTW, noise canceling works for dull back-gound noise, don't expect them to eliminate screaming kids. You just get clean clear sound, with no dull roar of a jet engine.
