best closed headphones for mp3 players???

Hello, 

How much do you like bass? you want strong bass response? 

ever considered the HD-25 I II? isolation is the best among closed phones, and bass is punchy. 

For portable uses, I'd pick the HD25 over the Denon.

Based on the size of the headphone. They do have different sound signatures and I would expect the D2000 to have more overall sound quality,

Have you considered IEMs ? nothing better if your priority is isolation.

I heartily second Sennheisers's HD 25-1 II 'phones for portable use, particularly since you own a nice set of Senns for home use. I chose the HD 25 a few weeks ago after a dismal time auditioning headphones specifically geared toward portable listening (my review is on the site now). Sound quality to my ears is really good, with tight, articulate bass that goes satisfyingly deep, with proper mid- and HF response for extended, and attentive, listening. All wrapped up in a rugged, non-attention-getting package (just the way I prefer for listening on the train or the like). And, yes, terrific isolation.

I had the HD-25ll 10 years ago.... and today I'll recommend the GMP 8.35, here more info: http://www.head-fi.org/t/406658/the-german-maestro-gmp-8-35-d-monitor-in-the-studio-serious-about-audio-indeed/345
