I'm in search of a pair of earphones or headphones that could reasonably survive on the Appalachian Trail. I have absolutely no experience using earbuds beyond...Skullcandy, iBuds, etc. I'd imagine they would be the most practical for a walk in the mountains, but again, I know nothing and so I would much appreciate any and all suggestions.
My budget is anywhere between $50-150. I've yet to settle on what I plan to drive it out of, likely just a generic MP3 player. Would prefer no amp, as battery life will be at a premium out in the sticks. If headphones, they must not be large and unwieldy. Listen to many genres, but if it were to cater towards one, I'd go for generic rock.
tl;dr - What's portable and doesn't sound like absolute crap for $50-150?
Thanks in advance!
