So I have officially broken my older pair of in-ear headphones. I'm in the market for the best for the price (within $100). It will be mainly used for the gym and walking to class. I'm classically trained as a musician, so I have done my share of the research. I'm just asking you all for any additional suggestions. The ones I've looked at so far are the Bose in ear ones, some Sony pairs, and a pair of Sennheisers. I'm not looking for superaural or circumaural headphones; I have an awesome Grado studio pair that I don't wear out in the public very often, but it is very impressive when hooked up to a high fidelity recording.
