Does any "good" headphone have a 3.5mm plug?

A few minutes' work with the soldering iron and you can create all the
extension lead you want.

Yep think that's what I'll do, been looking at CPC and Maplin this aft.

Handy tip: put the plug / socket cover on the cable *before* soldering
:-)

Ha Ha. Yep been there many a time. Does not seem to matter how many times
you've done this kind of thing its still easy to get carried away with
the soldering and find you've forgot to put the cover on first.
