Hi everyone, I know next to nothing about headphones, and this would be my first serious purchase. I've been doing quite a bit of reading, and it seems like there's both a lot of good and a lot of bad written about the ATH-M50s. I've also got a few other options to think about: Sony MDR 7506 AKG 240 Sennheiser HD 449 I don't listen to just one genre, so I'm looking for a pair with both decent bass and treble, an all-around good beginner's set of headphones. I'm definitely not limited to just these options. My price range is around $100, and I don't really want to go much higher than that. Any advice or suggestions? Thanks!
