Query: Looks cool but doesn't work

I purchased a family plan for my partner and I and we got these for headsets. Within 3 days we exchanged them 3 times each. None of them worked. Even the Verizon salesman couldn't make them work. We were never able to dial out using voice commands and it kept turning itself off and on. And in addition it was very hard to hear incoming calls and they constantly would fall off. We dumped them and bought Plantronics Voyager 510 model G and they work fine. Don't waste your time and money on the H500 Motorola. What's up Motorola?
