I bought some AM-90s, thinking they're what I was looking for. I think they're the worst earbuds, sound-wise I've had. It makes me miss my Jbuds and Creatives. When I turn up the volume all the way, they sound really sharp and irritating. I'm looking for headphones that have both a good amount of treble and bass - enough for oomph, but where one doesn't overpower the other by too much. I don't know all the technical terms - I just want them to sound good. For instance, the am-90s have some bass, but I would've liked to hear it more emphasized, as it is almost non-existant. And I think perhaps it is the high treble that is what is making it so sharp when the volume is turned up all the way, not sure.
I want them to last a fairly long time, especially if I pay a high price for them. Like at least 2 years - I'm tired of buying earbuds (the Jbuds and creatives) that don't last for more than a year. And I need them to be comfortable, of course, this is very important. The am-90s fit nice in my ear, that's one thing they got going for them. Noise isolation would also be nice, but not priority. Definitely want earbuds that go cord down instead of having them wrapped around the ears.
I listen to mainly punk and electronic music, if that helps.
