I love my 770's ive heard the 880s as well, the 880's are definately better no question but for 85 quid you really cant go wrong with the 770s.

they're VERY comfortable and really do make writing music queitly a pleasure. I also notice that if i write something on the 770s it sounds about right when coming back onto speakers.

best headphones EVER full stop...

and watching a film with them on is ACE!
