Headphoneus Supremus
By sub-bass extension i don't necessarily mean heavy impact and head-shaking but more just the ability to reproduce frequencies of 20-40hz. From what I've listened to I have trouble hearing anything under 50 or so hz on the Bose's whereas with my M50xs and crossfade M100s I hear frequencies down to about 30 hz I'd say. The gift recipient listens to a lot of EDM so that sub-bass frequency range is pretty important but it also won't be their only use!
Personal opinion: the Bose headphones are fine for EDM imho, and tick all of your boxes as well as the HD 280/380 or ATH-M50 could, but will "win" on comfort and being non-fatiguing (especially with lower quality sources). Do with that what you will.
I dont think DT770s are as good as your M-100s for EDM,but you could do a lot worse...in fact EDM is about one of the only genres that didnt make me wanna rip the 770s off my head and scream in pain.
Beat my record with them. :rolleyes:
As these will be a gift I'm essentially looking for a headphone slightly cheaper than the M100s but more comfortable and isolating and possibly slightly easier to drive amplessly. I suppose I'm looking for a similar sound signature.
I feel like asking this at the beginning would have saved considerable time and provided significantly more clarification.

If you really like the V-MODA sound signature, they make lesser models under the M-100 that (from my brief time with them) are relatively similar. None of them are going to be a problem without a dedicated desktop setup - they're fashion headphones after all.
