Input:
I've used a lot of different headphones in my days.  I always go back to the Sony MDR-V150.  They are the best sounding consumer headphones on the market.  They're cheap and they have amazing bass and treble response.  I've used ear buds that cost $15-20 and ones that cost $160 and the MDR-V150 is still better than all of them.  I would buy these headphones over anything else.  Plus ear buds can easily damage your hearing in ways that these cannot.  Be warned though you need to be careful with them.  I've had a few pairs break where the speaker attaches to the headband.
