What are some good headphones to get?

I don't want the most expensive headphones around (my budget is around $100), but I do want a reasonably good pair that are comfortable and have some kind of bass boost. They don't have to have bass boost, I would just prefer it. I know sennheiser are pretty good, but they are pretty expensive (I want to save as much as I can, $100 is all I have right now and I'm only 16 so I don't want to spend all of it). I would also like it if the build quality was pretty good, and I prefer the larger earcups that surround your ears, rather than sit on top of your ears. Can anyone recommend a pair of headphones that they have and like or a pair that would suit me?
