Review on Logitech USB Headset Mono H650e: Enhanced Communication in Black by Carl Higdem

Microphone became static after a few months. Called Revain went through the troubleshooting but had to give Logitech a supposed 1 year warranty. Logitech wanted to do another fix - the microphone is clearly not working. He explained that we have 8 such headsets - all the others work except this one. How long does it take to troubleshoot before Logitech replaces it? Not what I expected from Logitech - disappointed.
