I have these right now (company provided) [1]. They work relatively well, but they are uncomfortable if I wear them for more than 30 minutes or so, due to the way they sit on my ears. Also, noise cancellation would be very nice. My budget is as much as it needs to be within reason, but I'd like to keep it in the ballpark of $100 if possible. I mainly listen to music as background noise, so anything up-beat works - I typically turn on alternative / rock, or electronic depending on my mood. Comfort and noise cancellation are the biggest 'wants' for me.
