I just got my PSP today. I'm not too impressed with PSP's built-in speakers, and since it came with NO ear buds I caved in and bought a pair of the Sennheiser MX-500's from Amazon. My total bill was $14.33. Thanks for the recommendation. I already have a pair of Labtec Elite 840 headphones but those squeeze pain against my ears after a while, so maybe I'll have better luck with these ear buds.
