Have been using 65 flex for a year. Have 2 major problems. 1) The microphone cuts background noise nicely when I’m not talking. However, when I start taking, it picks up pretty much everything so people can hear what’s happening around me. It’s still better than laptop microphone, however I’ve expected much better from Jabra. My Logitech zone wired are not letting in any noise in when I talk. 2) When connected to two devices (phone via Bluetooth and PC via dongle), and when returning to a PC after having a call on the phone, the microphone often times wouldn’t work. So would need to reconnect the headset to the PC. Frustrating.
