This is coming from someone who owns many high-end headphones such as the HE-500, Denon D7000, Grado RS1i, LCD2...To my ears, the V-80/M-80 is second to none of the on ear category. The sound as a whole package is smooth and pleasing. Comfort could be better though, and it's the only flaw.
Only other contenders to the on-ear supreme is the Sennheiser HD 25-1 and Beyerdynamic DT1350. But both of those are at a higher price, this makes the V-M80 a no brainer.
