I'm a weird and particular dude, so if you don't get my thought process then that's ok.
This was my purchase process:
1) I want good headphones
2) Lots of Head-Fi people seem to have Grados.
3) Maybe I should read some reviews from other sites too.
4) Could they possibly be THAT uncomfortable to wear?
6) Why don't people like what they look like? I think they look cool.
5) Could the possibly leak THAT much?
6) I don't believe it...they can't leak that much, I'll be able to wear them at work.
7) Ok so I want either the PS500i or the RS1i.
8) Hmmm why can't I get them with the mini plug?
9) Erm I don't want to use an adaptor, it will look silly stuck in my iPhone. Do any of these have the mini plug?
10) Hmmm ok, so the lower end ones have the mini plug so they must be something that I can use with my iPhone and those other ones must be for studio use or real die hard home stereo fans.
11) The 80i seems to be a decent set of headphones, I guess I'll get them...I didn't want to use an adaptor anyway.
12) *Opens Package* Wow these sound great!
11) Crap, so that is what they meant by "leaks a lot". No way I can use these out of the house.
12) Who cares they sound great
13) Damn my ears hurt! Why can't they just make these things comfortable? I need a break.
14) Crap! The "E" series? Hmmm I'm still within my 30 days maybe I'll get those PS500s and return these.
15) Now I need to research in-ear headphones because I need something to use at work.
16) Maybe I should join Head-Fi
