Well, I'm not a crazy audiophile, but I thought this might be useful for some people looking to buy new head/earphones. If anyone would like to review/post about their current cans/earphones that would be nice... I've always looked for something comprehensive so that I won't be in the dark every time I try to buy a new pair of earphones, and so far I haven't found it. Let's make one then^^
Here's a great post on ABI for
headphones under $30.
Another great list from ABI:

From your friendly /g/ents over at 4chan:
hf buying guideWhat I've owned in the past:
Razer pro|tone m100 - nice bass, nice price ($35)
Klipsch Image S4 - overall warm sound, perhaps a bit overpriced in the faced of better competition
Etymotic ER-6i - avoid. simply, avoid.
JAYS d-JAYS - needs burn-in time, then matches the S4
JAYS q-JAYS - extreme clarity, accurate and punchy bass but not for bassheads
Head Direct RE0 - similar sound signature to the q-JAYS, but high impedance for amping (useful) and cheaper
Klipsch Image X5 - clarity, but overpriced and poorly constructed cable
I'm sure there are more, but for now I would recommend Hippo VB for bassheads (never owned, but I've heard great things), and for clarity/treble focused JAYS q-JAYS or the Head Direct, which is my current set. With the price reduction on the RE0, they're probably the best bang for your buck.
Anyone want to contribute something about headphones? I've never used them before. Only thing that would move me over is probably the wider soundstage compared to IEMs.
