Ok so both the NCredible and Solo HD's are terrible headphones. If you have 110 to spend get the ath-m50, they have good bass not over powering and a great overall can for only 110. Stay away from the Beats line ( unless you can get the pros for cheaper than the MSRP they are the only decent headphone in that line).
I use my HD439 for gaming and music. They have a good sound stage so good for gaming, they are also really good for music. Good bass, mids and highs are on par with Sennheiser sound. Only problem is the ear cups can make your ears a little hot because of the velour.
