Absolutely amazing!!!! The Ear Bud covers are astounding. Haven't had imaging this good since Sennheiser Cordless 146 I think. Using a Sony 16 Gb player, music ripped at 192 kHz, Windows Media Player......... not lossless, just straight thru. The musical nuances are truly astounding! Super High recommendation!!!! I believe Sony has knocked on the high-end Headphone market for sure.
