I figured my first post should be contributional rather than interrogative.
I currently wear a pair of Koss Porta Pros for daily usage, with a pair of cheap earbuds for the gym, just to avoid the sweat. The impedence is a little high, so it doesn't get loud when you're already experiencing the masking effect (IE ambient noise is drowning out your music, so you crank the music to drown out the ambient noise) and they're over-ear so the sound does leak, but they have a Lifetime replacement warrenty and the non-inline control version 30 years old and tried and true. $50 retail, $70 for the inline controls (but no mic)...and did I mention I bought mine for $35 on Amazon? They were recommended to me as being the better balance of quality and frugality, and the numbers and the experience back it up. But I encourage you not to take just my word for it. Do some research, and if you can, physically test them yourself. If you can't tell the difference no matter what you pay, then you should not pay more than the minimum.
If the impedence bothers you, you can get a preamp and run that between the two, but you'll draw more power.
I have an opinion on Beats, and it's not kind.
