Summary: I was able to use this unit for one day before it died on me. I was impressed and know that I likely just received a dud but was more frustrated with Plantronics than the product. I called the Canadian toll free number that apparently takes you to the U.S. tech support. The rep did not confirm where I was calling from and proceeded to direct me to the procedures for U.S. customers.
Summary: I purchased this headset for my Samsung Replenish because I have trouble hearing through the handset when there is outside noise. This headset is very nice. It fits well and looks good. The call quality is very good. It connects easily and remains connected even when I walk away from my phone. I've been in the house and my phone in the car and I've stayed connected.
