I've recently gotten fed up with my headphones, a cheap pair of Coby's from Walmart.
I go down to the nearby Starbucks, jack into my iPod Nano, and listen to music while getting work done. The Coby's just sound awful.
I'm looking to upgrade, did a lot of reading on this site, and narrowed down my options my to the ATH M50 and HD 25-1 ii.
I'm hoping to keep the price between 100 and 200 USD.
I listen to all sorts of music, but most of it tends to be ska, punk, metal, electronic, and classical. Additionally, I have a larger head, and wear glasses.
I think comfort and quality are the first of my concerns, and could be talked into spending more if I could get both. Also, I don't much really care if the sound leaks either, so long as my top two concerns are met.
