Indoors, it's gotta be over ear, coz quality. A decent pair of overear as well
When outside, I use in ear, they are still fine to listen to, it's not like I want super quality when outside anyway I'm only gonna be listening to Nirvana or something not checking out the latest super underground ambient. Plus I want to be able to hear if someone talks to me, if I have over ear I can't hear a single thing
On ear are just useless in all situations lol
For all those who are complaining about headphones breaking, seriously, just fork out some cash and buy a decent pair; in the long run you'll probably save more money anyway. I have a pair of audio technicas they're made out of metal, they aren't going to break they will last a lifetime, it's so much better
