I started out with sennheiser HD428's and really liked the signature of the headphones and the only complaint I had was that the bass wasn't as strong as I would like it to be. I decided that I would rather try in ear headphones so I got some RP-HJE 900's and loved them. I loved their balance it was great balance of everything, but within 3 months my left driver gave out. so instead of buying another pair of 900's I decided that I can upgrade. I dint want to spend too much money so, probably looking for second-hand with a max budget of $150. I am looking to wear these for long periods of time at work, but I am glad to sacrifice on comfort for sound. Hence I did some research and could not decide between these.
Ultimate Ears TF 10's > ~$130
Superlux HD668B > ~$50
Fisher Audio FA-003/ Brainwaze HM5 > ~$140 (amazon) new
ATH-m50s > ~$140 (amazon) new
Im leaning towards the TF10's or FA-003/HM5 but if there are any other alternatives please let me know/ help me pick the best for my money.
I listen mostly to HipHop/rap, Rock/Metal, Piano/Guitar, with a bit of mainstream stuff
