Koss CS95 Headset
Overall good quality for the price.
I've tried a lot of headsets, many in the $70 to $130 range, and this one outperforms them all. Clear and loud in the ear, and it works perfectly with my Avaya phone. Comfortable to wear, too. I only took off a star because the cord is so ridiculously long. But that's just me. A lot of people would really appreciate a long cord, so if you're one of them add that star back on!
