Hi,
 
I currently own a pair of sennheiser PX360's, however the sound is starting to go in one ear (I've had for quite a while and I have a habit of chewing/playing with the cable...). So far I think I have narrowed my choices down to either:
Audio Technica ATH-M50X
Audio Technica ATH-M40X 
Logitech UE 6000
 
I have a budget of around £100, but am willing to go up a little (if it's worth it). I mostly use my headphones for listening to music (mainly rock/metal), watching tv shows, playing video games, practising drums and guitar. I can often spend 8 or more hours a day with my headphones on so comfort is a high priority, also I like the idea of detachable cables as I have a habit of chewing them...
 
What would you recommend out of those, or are there another pair of headphones that are better suited for my purpose?

Try them out. People are build differently some find one headphone comfortable and others don't. 
 
My friend do say the M50X hurts his head after a while as they clamp with quite some force. 
 
Personally over ears or on ears makes my ears hot and a bit sweaty (and this is in Canada in winter where it's cold and dry). So I find IEMs more comfortable but only when they fit correctly.
