Please. I'm not speaking from personal experience, but I have only seen almost exclusively negative reviews about Skullcandy. Mostly, they're about how fragile the headphones are, not necessarily how bad the sound quality is, and how overpriced they tend to be.
I use a pair of Sennheiser HD205s, and they're easily the best headphones I've had the pleasure of using to date, but they're also generally regarded by others as exceptionally tight. Behind these, I've also used the Sennheiser HD202, Plantronics Audio .360, Razer Moray, and two pairs of Sony headphones that I can't remember. So I've never used a particularly expensive pair.
Strictly from reviews, the general consensus is that the Sennheiser HD202 is the best all-around buy.
I've heard insanely postive reviews about the
JVC HA-RX700, but they're also
colossal which might turn you away. I'd still like to have a pair of my own, but I'm just waiting until I can afford a legendary Audio Technica ATH-A700.
I'm by no means an "audiophile".
Edit: The best advice I think I can give would be to be very careful about what you're going to buy, and look into
a lot of possible headphones. Browse Newegg's selection, and look around Amazon for more products by brands that you saw on Newegg. These are hopefully going to be something that you feel comfortable using for at least a year, after all.
