I will admit that this headset is a great one. Easy to operate and very clear on my Treo 700wx. However, the propriety charging system sucks! They use a small, non-standard connector between the headset and the charger. Mine stopped working just 3 weeks after I got it. When checking for repair, I was told that I "must have abused" the headset. I guess they consider pluging and un-pluging the charger abuse. Dumped the set and purchased another brand.
