"2 years of use with great service and minimal grief."5.0 starson by samuel351c
Pros: Clear sound, Durable construction and have been taken everywhere.
Cons: Wiring is coming loose in the mic-side earpiece and causing the opposite side to fade in and out with a lot of crackling. I think the wiring between the volume adjust and headset could be thicker or at least better protected to match everything else.
Summary: I gave this unit a full 5 stars because, despite wiring connection problems now, after more than two years I've had great service out of mine and when compared to similar models, this was by far the best. Unless Logitech comes out with something more durable for the money, I'll probably purchase another USB 350.
