Overall good, Must get used to comfort
My first pair of higher end headphones in the 300 dollar range. I have a pair of audio technics ath m50's (160$), Sennhieser HD 558's (170$) and an old Skullcandy Aviator (150$, which by the way is a great sounding headphone believe it or not). Of all the headphones these are the most musical and clear (everything else sounds under-water srs.). Treble seems a bit exaggerated yes, but the sound of a fully open headphone is something I have never heard before. To me, The sound straight out the box sounded "HD", like buying your first HD-TV after watching a standard SD TV for more than a year.. I expected the sound to be dull and flat with little bass and a wide sound stage but it was actually a very punchy "In the air" type of sound. Allmost similair to an open ATH m50 with a brighter treble response....Some may say it's just "bright" but you can hear a mix of warm in there... So it's more of a mix of bright AND warm which is interesting. Sound stage is wide but you only really notice it after your ears get used to the sound signature of grado (about 3-6 days). After burn in, headphones reacted even better especailly with high quality recordings (FLAC or straight off the CD). Comfort just sucks. But I got used to the pain after about a week.
Pros: Punchy, accurate sound for an open headphone Slightly warm sounding Looks cool... Thick cable
Cons: Comfort simply blows May be too bright for you Bass is beautiful (seriously) but does no dig deep like the m50 does.
