plenty of people have had a look but no opinions yet. just to let you know that i bought a pair and ran with them this morning, and as per the reviews i read they get a thumbs up from me.
My run included sprints, stairs repeats and hill repeats as well as a slowish jog back home and the earpods stayed in place perfectly. they are very comfortable but they are not a perfectly snug fit and felt like they were going to fall out on several occasions, but they never did. i had the cord tucked down my shirt and a few times i felt it tugged on by my collar etc, these slight tugs would have easily removed the old ibuds from my ears but the new ones didnt budge. its probably this that made me feel like they might fall out at any time so it may just take a little getting used to.
Sound quality probably isnt perfect and they dont drown out surrounding noise but as a runner that is probably a good thing. i would agree also that if you want to spend £100's then there is bound to be better out there but they are probably the best that £25 can buy.
