I recently purchased a pair of Sennheiser HD 497. Do they need some particular treatment at first? Something like a pink noise treatment for speakers? Ah..how do you live with 3 mt of cable if you want to use them on the go?
The HD497 are one of the best headphones I've tried ! Much better than any "generic" headphones you may own, and even better sound than the Sony MDR-V700DJ
