Has worked great for me so far. The mic button "slips" easily, so I am a little concerned it might get switched to off when I dont want it to. 3Filter 5: Fc 5000 Hz Gain -6. Adding several photos attempting to show difference in sizes of old style versus new style. It seems well made, although the wood pieces are a bit thin. Nice piece. I purchased these from a recommendation. This post will never last on the reviews. But when you are at a desk, you can keep the case plugged into a USB power cord and it will continue to charge the headset. This clip is super sturdy so I can clip them to my keys, my wallet, my pants loop, point is, I wont be losing them again!
