sennheiser tends to have some good midrange / lowrange models, but I don't know if you'd be able to find one that low. Plantronics gamecom 780 is one of the better budget buys but the mic is permanently attached
Siberia V2 is another option if you could go $15 higher, and though the mic is permanent, it retracts into the earcup when not being used. it's barely noticeable and most people wouldnt be able to spot it. solid headset for the price
best of luck my friend
