Sennheiser PCX 300 vs. AKG K28

Hey Everyone.....

Please help me decide.
I travel quite a bit via plane for my job.
Which one of these Noise Cancellation Headphones should I get? They both received fantastic ratings from various articles on the internet.

I haven't heard great tings about the K28s, and haven't had a chance to play with the Senns. But, I think you can't really go wrong with Sennheiser. I've listened to maybe 8-9 different sets of theirs and never been disappointed. Hell, there are 4 sets of Senns on my desk right now... (HD580, HD435, PC145, MM50)

Sennheiser, that would be my choice.

Ioman & Neuroman.....Thanks for your opinion.
One more question....Are any of you familiar with the Ultrasone HIFI 700? While they are not Noise Cancellation Headphones, I am considering buying these. The reviews and ratings have been so high, they are hard to ignore. The question is will they block out at least some noise at a minimum to at least compete somewhat with the Sennheiser PXC 300. You guys have a technical expertise where you can explain the differences between the 2? If I decide to buy Ultrasone, will I miss much from a technical perspective?
