I have two suggestions, one under your budget and one over.
Both are Sennheisers.
These are the [ame="http://www.amazon.com/Sennheiser-504631-HD-558-Headphones/dp/B004FEEY9A/ref=sr_1_1?ie=UTF8&qid=1396819209&sr=8-1&keywords=sennheiser+555"]HD 598s[/ame]
And these are the [ame="http://www.amazon.com/Sennheiser-HD-518-Headphones-Black/dp/B0042A68R8/ref=sr_1_3?ie=UTF8&qid=1396819209&sr=8-3&keywords=sennheiser+555"]HD518[/ame]
Both of these headphones are absolutely amazing sounding. Incredibly clear, audiophile headphones.These are the types of headphones used in music studios so producers can hear exact tones when listening back to music. Beautiful surround sound when gaming, you'll hear every note when you're playing music, you'll feel the explosions in your game. Overall the 558s and 518s are amazing audiophile headphones that have built in amplifiers. You'll love these if you get them, Sennheiser makes incredibly durable headphones. I have Sennheiser HD 555s, and I got them about 4 years ago, these things have lasted me, still sound beautiful, and have only small cracks from my years of using them. These things are my go to, the only problem is that they are open ear style headphones, so your music and sound will leak out. But besides that I whole heartedly recumbent the HD 500 series headphones from sennheiser, amazing sound, clear highs and lows, durable, and beautiful looking.
If you want to make them a headset, simply get this that clips onto the headphone wire. 8 bucks on amazon.
