I just sold a pair of Vmoda M-80 last week because I wasn't overly impressed, the builds not as good as Vmoda and the appearance might not have that Vmoda spark. but for sound I rate the HPH-200 higher. Tighter bass response, clearer mid range, basically more extension around the mid range offering more detail better clarity, more than that natural timbre and air in the stage. 100% no problems recommending them over M-80. What you need to remember though is they're open air so sound leakage will occur, I had no problems using them at night without annoying anyone however. Don't hesitate on trying them, you'll be pleased over M-80, I can say that with 100% confidence. HPH-200 is just a better sounding headphone.
Okay than... hmm... These are looking enticing. Do you mind if I ask you for one more comparison? It'll be something a little bit more (open vs semi) similar; how do these compare to the Philip L1's which I can pick up for $120? That's the other headphone I'm looking at to replace my V-Moda M80.
