Christmas is coming around the corner and I need some advice for a "starter" headphone. I currently have the sennheiser HD 202 but they don't cut it and I want an upgrade. Two headphones I've looked at are Grado sr80i and the Sony MDR7506. I mainly listen to Hard Rock, Jazz, Pop, rap, and electronic/dubstep. Of the two which would suit my needs and if neither work could you tell me a headphone at about $100 on amazon that would be better.
