I'm looking for a good set of headphones to use while on the go. I prefer on or over ear, but in ear is fine too, I'm mainly looking for good audio quality. Something like Beats by Dre, but not so overpriced.
Budget is 30-40$, maybe higher if it is worth it. I know I'm not going to get super quality out of that budget, but better than what I have for sure.
On the go: ie: no external power required beyond a 3.5mm headphone jack.
