Hi all.

I am looking to get some decent headphones to replace the standard iPod
buds.

These are my main requirements:

Over head type: so I can just hang them round my neck instead of
fiddling with tiny buds

Closed: cut out some background noise on tube and stop bothing others
with sound leakage

Punchy Bass and crisp treble:

So far these are the ones I'm considering:

Senheisser HD 200
Senheisser PX 100 (for cheapness and sound - though not closed)
AKG K44
Technics RP F550
Bose Triport (If I'm feeling extravagant!)

Any advice on these or any recommendations for others greatly
appreciated. Prefer to spend around £40 to £50 but would
spend more if necessary.

Cheers guys
