Just received my Sennheiser HD598 headphones and all I can say from just using them for an hour, is WOW!
Tested them with my Xonar Essence STX + all songs@320kps mp3's.
Started off by playing Emeli Sande's "Breaking the Law", a great vocal piece and I was floored with the clear vocals the cans produced.
I then moved onto 30 Seconds to Mars "Attack", a quite standard heavy rock piece filled with distorted guitars and a great vocalist, I found myself really focusing on the vocals more than anything as the HD598's really seem to clear up the noise you sometimes hear with some distortion laden songs.
For a more fun approach I then switched to a japanese alternative rock band called Ling T. Sigure who are notorious for their interesting vocals, abrupt guitar riffs and insane screaming. Their track "Boukan" starts of as a very quiet piece with just vocals, getting more and more loud and ferocious. This song was jaw dropping on the headphones, I have never been able to properly hear the drums because of the chaotic style of their music but here I felt every bang, every clash of the cymbal, every chord struck on the guitar, absolutely fantastic!
Next up I played the song "Sovngarde" from the game Skyrim, a simple song with nothing but chanting and heavy drums. The headphones were flawless, I could easily hear each section of the choir alongside the drums.
Finally I played one of my favourite songs, "Do it for me now" by Angels & Airwaves. No words, just stunning.
I'm very chuffed with these headphones, build is quite solid despite them being made of lightweight plastic. They are comfortable to wear and while I'm not a fan of the colour scheme it's not a big deal as I won't be wearing them outside. Only disappointment was the packaging, I found it very spartan and the plastic the headphones were encased in didn't exactly scream "high-end" at me. Having owned a set of HD595's a few years ago I was also disappointed there was no holder included.
Overall 9/10.
