Drop + EPOS - IMPACT 860 ANC

Exactly this! Most of the suggested option in this thread do a fantastic job at filtering out the background noise from your *ears* but mist don't do anything, or don't do much about filtering the office noise from the *microphone*. There's a few sample videos on YouTube from channels like HeadsetAdvisor or CallOneInc that demonstrate how various models perform in this situation. You want to factor in both how well the headset filters out the surrounding noise and what the voice quality sounds like post filtering. Some models (e.g. Yealink BH76+) do a pretty decent job of filtering the background noise, but at the expense of audio clarity... your voice sounds very narrowband and rough. In my experience, after testing several options, I went with the EPOS Impact 1000 series (I went with the 1061 ANC) because it had great microphone noise filtering and the best (by far) microphone audio quality. The earpiece ANC is *okay*, but nothing amazing... cancels out some of the background noise but nothing like a good set of over-ear ANC *headphones*. The EPOS 860 ANC is the exact same headset but with wired USB-C connection rather than Bluetooth.
