I think I paid about 50 quid for my seinheisers and I personally love 'em but I know some people really don't get on with them. They don't reckon they're loud enough. That's a good thing in my book cos I still want to be able to hear in 10 years time, and I reckon they are plenty loud enough.
The plug-in wires on the headset with the seinheisers is a big bonus for me cos I'm a clumsy **** and have knacked loads of pairs in the past by bending down to find a tune, standing on the lead, standing back up and ripping the lead out of the earpiece.
