Well, I've been giving these new headphones a good try out.....I played the "Michael" disc all the way through, because I was enjoying it so much.
Two words come to mind, DETAIL & CLARITY. Vocal & instrumentation wise, you really can hear every little nuance ! ( Early days, but regards detail, I think they're possibly some of the best headphones I've tried out ? )
I played Toto IV in redbook CD / SACD / Flac file formats, they all showed impressive results, again highlighting detail. SACD & Flac, very natural / live sounding. I suppose there was a brief thought, that I was going to experience a 5.1 explosion in my head, given Sony's literature, but of course, that's not the case.....but what I have experienced, is a more than favourable listening enjoyment.
I also tried out REM / DVD-A ( Around The Sun ) Even more impressed with this disc ! I tried out a couple of the new HFPA Universal discs - Stevie Wonder ( Songs In The Key Of Life ) Serge Gainsbourg ( Histoire de Melody Nelson 5.1 ) Again both impressive. Detail being the key word at present....
Comfort wise, very similar to Bose AE2's, which are some of the most comfortable headphones I've tried !
I purchased some Sony MDR-1NC headphones earlier this year. ( Which I find either very impressive, or not so, depending on what's being played, and equipment used ? ) Compared to the MDR-10RC's, I don't find them as comfortable....and vastly overpriced ! ( even though they're NC. ) I may not have bought them, if the MDR-10RC's had been available at the same time !
Anyway, i'll go & give my ears a rest for now....OR TRY TO !!
