Poly Voyager 5200 UC Bluetooth Headset (206110-101, 7K2E1AA)

Works great, live there’s an app to update

Works only part time

I have been perching this phone for a long time, with no problems until one year ago I started having problems. After 3-6 months they stopped working. I have 3 of them that are not working. And I cannot be perched anymore because None of your texts seem to know What is the problem
