Fostex T50RP isolation is so-so, falls behind DT1350 noticeably. Paradox is a bit better due to more damping, but still lots behind. It's also not closed, it's vented.

I think if I was in the market for a closed headphone for work (and didn't need it to double as a on-the-go portable) I'd grab a Paradox.  I hear the isolation is really good.

Probably I will try to modify myself Fostex T50RP, Paradox price is too high for me, if I take in account that some guy played with damping materials on these. I respect peoples work but it is more fun to try mod it yourself. Also Fostex based cans are large for using on road, bus or at work. I need on ears (can't use in ear) Anyway thanks for suggestions 

I see that there are some good sounding DT1350's but hell who knows which version will be shipped for you,  Total fail Beyer TOTAL, BTW my friend has them and I listened for a while and I thought I could go out now grab any 20$ can from next electronics store and I will have better phone

If affordable and fun is your thing just get an AKG K81/518. It sounds like a HD25 without its shrill peak and very nice bass. Not a lot of detail though.

Otherwise the M50 is good enough to audition.

What a good idea they look interesting and cheap  I will check out them Thanks
