Nice review! I've been looking forward to reading more impressions of the XS since I own M-80 and 100 as well.
LOVE the M-100 for electronic music.
 
This could be a terrific headphone to recommend to someone who's got a very limited budget it seems. AWESOME!
I bought my nephew a pair of V-MODA M-100s for Xmas last year (he begged for Beats) and he LOVES em. He's become the better quality headphone evangelist at his junior high school!
NOW the other kids parents can get into V-MODA for less money. LOVE that. 

What a great review definitely looking into these now!!!! 

Though not necessary "classic" audiophile quality, I always consider V-Moda a brand for a "modern" audiophiles   M-100 is great for EDM, no doubt about it.  Being EDM-head myself, I do value vocal quality (I'm more into a commercial EDM), so VS will be edging out M-100 in that respect for me

Love the pics

very nice review, i have the same colour combination for the xs and the m100s

I'm so used to black headphones, kind of glad this one white/silver.  Just hope white leather/pleather doesn't get too dirty or discolored over time.  Also, black plates are great for engraving, otherwise it looks stealth.  With silver plates, they look super cool on it's own without any engraving.

Nice review and the pics are awesome. Which do you think are better in overall sound quality, the Dolphins or the XS? Do you still consider the Dolphins at the top of the list of all the headphones you tested or they were already replaced by the XS?
