So, what kind of environment will you be using your headphones in? There are different kinds, those that isolate you from sounds around you and others that are open and tend to be kinda comfy.
I notice you're from Canada, so my usual recommendation of the Sony MDR-7506 might be a tad over budget unless you can find a good price online. Others to consider might be Grado SR-60, SR-80, Sennheiser HD-280, and Shure in-ear monitors.
