Question: Better headset than Senn PC 151 for under $100?

Okay, so my boyfriend bought me the Sennheiser PC 151 headset and I've been trying to outdo him, but I can't find anything under $100 that sounds nearly as good. He has a lot of external noise at his place and school, so he would need closed-back. Anyone know of a headset that could rival these? We use the mic a lot, so I wouldn't want to get him headphones and a clip on mic. Thanks!
