Just got this baby today, i would say thinksound on2 deserved to be priced MUCH higher than this.
sound quality;
abit ,just really really alittle, recessed on treble, alittle bump in lowest frequencybut balance-wise. I felt this headphone is boosted equally across the whole frequency. Why?, it sounds much exciting and fun to listen than hd600 and hd650(which i own ). I tried multiple track which each track shines differently in term of frequency respond, for example;
Brian Mcknight; The evening with - My kind of girl
Daft Punk ; Discovery; Harder,Better,Faster, Stronger
Bach's Two and Three part invention studio session; Glenn Gould
Sonny Stitt; Now!; 'Surfing
Art pepper; Intensity; I can't believe that you are in love with me
Bruno Mars ; 24k magic; 24k magic and Versace on thefloor
All of above track play really nice on thinksound on2 while hd600 and 650 both would be depended on genre
