Consider the Shure SRH 840s, Everybody says they sound better than the M-50s. Knock out the V-Modas, I had them and you really can't compare them against these real prestigious brands.
Consider the SRH 840 if you have a skinnier head, otherwise they would hurt A LOT
M-50 if you're head is rounder, bigger, or just.. different...
Also take a look at the Beyerdynamic DT 770 pros too. They're said to be the best sounding hands down, but the looks make me puke.
SRH 840, ATH-M50, and DT 770 Pro was the 3 I narrowed down for my ~$150 headphone choice.. (I went with the Shures)
No regrets. Out of the box, they knock my old Crossfade LP out of the air
