It took over a year, but Poly, the company formerly known as Plantronics, managed to fix this one-of-a-kind headset. This month, they have released a firmware update and the release notes for version 513 state two changes:
Updated audio tuning to improve transmit performance
Enable HD Voice by default
“Improve transmit performance” is corp speak for “we are sorry, but it was completely broken and now it works”. The issue was that your voice was no longer transmitted properly. People on the other end could no longer understand you.
I need you to install this update and tell me if your headset is OK now.
Mine was never broken, but Poly changed something in the hardware and newer ones did not work in loud environments. Old and new with the same firmware. Old one worked, new one did not. Then I was told that they changed the hardware yet again, and now it would be OK. I told you that you would be safe now, but you were not.
The 513 firmware changed that. I have multiple reports that 2022 Voyager 5200 are now working properly. To be clear about this, we are looking at three generations of the same hardware and I do not know exactly when they went bad. Old ones which are way out of warranty were never broken. Those bought in 2020 and 2021 had a problem. Newer ones are now as good as the really old ones.
If you have a 2020 or 2021 Voyager 5200 please install the 513 firmware and try to call from a really noisy environment. In a car at 100 km an hour, with the window down. Can people understand you? They should. Let me know.
And the other change? HD Voice should be enabled. Yes, please. Otherwise, you sound like you are talking from the moon.
