I'm leaning towards Monster's Turbine.
They have pretty awesome reviews BUT I do not like how they never list their dynamic range, as I like to know these sorts of things.
I'm also looking at JVC's Black Series.
As they look like they have some hot features. For example, carbon casing and driver-in-ear design.
I'm not trying to buy a $600 headset, nor am I looking for 4-100,000 response. I just want some solid, good-sounding in-ears. And I do want the best for my money in the $100 or less range. Any tips, suggestions, advice on what to look for other than dynamic range?
I forget what I paid for them, and they're nowhere near the quality you're looking for, but I love my Skullcandy buds. They're super comfortable, and even with my fat ass on the treadmill, they never fall out.
