Cool, thanks for that. I might try the 450's without smartphone control, as I don't really have any need for it.... And the only other difference I can see is Alu vs Brass housing....
Hey Matt, my headphone / earphone collection is in massive need of thinning and I have an as new pair of those Sony MDR-EX650's... I don't have the packaging anymore but they've genuinely only been used for a couple of minutes at home. Happy to sell them for cheaps...
For in-ears, I'm a big fan of the Sony MDR EX650. They sound great for most things, have excellent isolation and they're pretty tough.
