I bought my Sennheiser 212 Pro headphones (pic attached) after reading their review at headphone.com and they have served me very well.

It is now 4 years and three cable replacements later and I finally need new headphones. The following are the key features I am looking for:

1. Bass and SQ - I like the bass of the 212s
2. Isolation - I work in a noisy office. As little sound in and out as possible.
3. No Amp
4. No Mods - I live in Kenya, Africa. So... shipping cans for modification or getting parts from other sources... would be hard
5. Not too expensive. Aiming for less than 200 USD
6. Full-Size. I am not keen on putting things into my ears.
7. Durability.
8. Used On - PC/Laptop, no preference for portability or looks.

So far I have the following list, from reading lots of posts and recommendations... I zeroed down to the following list.

HD 212 Pro - I am tempted to get this again.
HD25-1
AKG K27i
AKG K 26 P
beyerdynamic DT231
AKG K-81DJ
EH 150
beyerdynamic 250-80
Beyerdynamic DT770
Sennheiser HD 25
Equation audio RP-21
Sony MDRV6/7506
Sennheiser HD215
Ultrasone HFI-780

I am willing to spend more if I can get a big quality improvement.

Basically the headphone has to be better than the HD 212 Pro. Please feel free to suggest something that's not in the list.

I avoided the Audio-Technica because of the lack of powerful bass and the Denon's because they do not isolate so well.
