Have not had them long enough to wear for long periods of time yet. Will report back on how that goes. It appears as far as comfort is concerned, it improved for a lot of people, but also worsened for quite a few as well. It sounds like instead of increasing the amount of ears these fit into comfortably, they simply shifted to a different set of customers for which they'll feel comfortable.
For me, personally, the original earbuds were not just uncomfortable, but actually painful to have in my ears. These are very comfortable and light, at least for short periods of time (all I've tested so far), which I did not expect for having the plastic right on the skin (no foam pads, etc).
For the record, my ears are rather easy to please when it comes to SQ, so apologies for my rather enthusiastic first post regarding the SQ, but of all the earbuds I've tried so far (which does not include Yuin or high-priced earbuds), these would be my favorite. IMHO they easily beat any earbuds available in the Sub-$30 range, if not maybe Sub-$50. Certainly there are plenty of IEMs that sound better but I hate IEMs. I have not found a single pair I can wear comfortably for long periods of time. The marshmallows are the only ones I can wear comfortably, and even then I have to stop after about 45 minutes. As far as SQ vs. the IEMs I've tried, I'd say they are better than JVC marshmallows, better than Meelectronics M6/M2/R1, better than Sony MDR-EX36, and par or slightly below Bose IE/IE2 (which sound good to my ears but are overpriced and have a crappy cable). Of course, something like the Shure SE215 puts the EarPods back in their place... but with the EarPods at 1/3 the cost of those, that's tough to justify.
Overall, not an audiophile earbud by any means, but pleasant sound, and anything that brings the masses better SQ is good news to me. Glad to see at least a decent earphone finally getting into the hands of millions. Far better than any Skullcandy crap
