Sennheiser PC350?

Does anyone have experince listening to these? How do they compare to the Sennheiser HD280 (also closed) or HD555 (open) in terms of sound & music quality? I would imagine they'll definitely be better for gaming than the other Sennheisers.

Thanks,

Wish i could help you.

It feels like we're the only people who know about these headphones.

Maybe they're on the todo list at Sennheiser's PR department.
