First off, I'm relatively new to the headphone world and I have a few questions about buying a new pair. I have a pair of Beats Solo HD's, and honestly they're awful. I've had em for ahwile but I can't stand em anymore. Can't wear em for more than 30 mins-1hr at a time, and the sound just isn't all that great. Definitely not impressed for them costing as much as they did. I've been looking around here on the site at some of the reviews, and have been seriously considering buying the ATH-M50's.
1. Are they good headphones/good for the price?
2. Do I need to buy a headphone amp with these?
3. Coiled or straight cord?
4. Are they good for primarily rock/metal?
Any other useful information is appreciated.
