I currently use Sennheiser HD650 at work, but am looking for a closed can for a reasonable price. say about 250 euros to use with my Xonar Muses. I have tried the Focal Spirits ( all of them Spirit One, Ones S, Pro and Classic) and liked the sound very much. Could not wear them very long though, as I wear glasses and the comfort and durability was questionable. All 3 of mine developed cracks, which was replace under warranty. Same goes for the NAD HP50, seemed to lack punch under 100Hz, possible sealing problems. with my glasses and funny shaped on the head. V-Moda M100 good fun, but to much bass for classical music. Fidelio L2 was pretty good, but seemed bit to cold and metallic sounding. Nice open sound and tight bass though. Oppo 3 I have not tried, but their value proposition is very poor in Europe compared to the States, (about 573.94 dollars). I have not tried the ATH-M50X though and was looking at it as a next candidate. Price seems reasonable and value pretty high. Some pretty good ears like them too , (Tyll, Bob, Lachlan, etc.) I am not looking for something like the HD650, but something that has good dynamics and tight punchy sounds. Anyone here has some thoughts how these compare to those I have heard?
