Well, as far as that goes, I'm not 100%. The bass is pretty good and it has a decent range in sound. Could be a little crisper though. But if you're paying around $30 for them I think you'll get your money's worth. What I usually do if I wanna test drive some headphones is borrow a pair from best buy (buy and hold onto receipt to return, there's usually no restocking fee, but double check if you're not sure), and if I like them, look online for a better deal. I was glad I did that with the CX680s, I was hyped about using them, but they just kept on falling outta my ears so they gotta go. I know they should have CXs there, and since Best Buy is in love with Monster for all the suckers that shop there, they ought to have some Turbines. So try before you buy if you can and compare to see what kind of sound you prefer.
And for those using ebay to buy headphones, be on extra alert. There's a lot of bootleg headphones(Sony, Sennheiser, Shure, etc.) running around, especially if the sellers are from HK or China. Can't really trust their feedback because most of the people that buy from them wouldn't know the difference. For the inexperienced ear, they sound pretty good, but they're made of really cheap materials and will fall apart pretty quick. They got the packaging and everything too, when I was in HK it was an eye opener seeing what they had as far as bootlegs (Sam Sui Po, if it has circuits you can probably find it there). Bought a couple, they were just disposable. I just avoid buying headphones on ebay for the most part and lurk for good deals on legit online stores or if I do go ebay, high feedback sellers from the states(watch out for sellers that are listed in the states but send their stuff from China). That mostly concerns earphones though, harder to pull off with over the heads though I guess.
