I tried in-ear buds but was never comfortable running with them, especially in urban settings w cars and such. These have great sound, and don't jostle at all. The battery doesn't last quite as long as ear buds but that's a low priority to me.
I often forget that I am wearing these. They are so comfortable that I sometimes sleep with them on. I am on my second set because the charging port separated from the case on the first set. I use them everyday, like all day long though. I love that I can hear what's going on around me while using them. Maybe the biggest advantage of this style is I have never lost them! With standard ear buds, I was always taking one bud out and putting in my pocket. I lost so many ear buds to the laundry machine that I had to try something new. Last thing, I suggest trying them on. I was not impressed with the full size set because it felt like I had a hat on backwards and because the strap would rub against my hoodie. But the mini set fits tighter to my head and is very comfortable for LONG sessions (pretty much all day long). I have to remind myself to take them off now and then. You really forget that you're wearing them.
Sounds quality is AMAZING compared to the first gen. No vibration or distortion at all, even at full volume. Sounds as good as over ear headphones. Extremely happy I broke my 1st gens. Lol
