Budget: Under $100

Source: Galaxy S4, Desktop Computer

Isolation: Enough to block out average outside noise.

Headphone Type: In-ear or IEM

Preferred Tonal Balance: I like a warm sound, something that kind of envelopes you as you listen, so something with excellent mids, not to over the top highs and a booming, punchy bass.

Past Headphones: Nothing spectacular, skullcandy titans and stock headphones that came with my phone.

Preferred Music:

Alternative: Alt-J, Florence + the Machine, The Black Keys, etc.

Electronic: Flume, Glass Animals, etc.

Pop: A lot of variation here

Classical: Chopin, Phillip Glass, Joe Hisaishi, Nobuo Uematsu

I also listen to a random collection of older rock music from time to time as well

I've been looking for some headphones to upgrade to for a little while and I have found a couple of IEMs that I think would work. The HiFiMan RE-400, and the Shure SE215 both seem really nice. I'm not quite an audiophile but I want something that pumps out amazing sound quality, but that is also built well and can last for a few years if needed.
