I've returned to my other favorite forum, Head-Fi.org, in search of some new headphones. I'm a man of value; I buy the most cost effective items I possibly can. I currently own: Koss KSC75, Sony MDR-V6, & Audio Technica ATH-AD700. However, I think I might be selling the AD700 as they don't have enough bass for me. It makes jazz, in particular, sound AMAZING due to the airy soundstage that really gives depth, width, & separation of the instruments... but it sacrifices the punchy bass too much for me. Right now I'm thinking of buying three more cans (AKA headphones): Ultrasone 750, Ultrasone 2500, and maybe an Alessandro MS-1. You guys use headphones? Any good ones??
