I’m not sure if this is possible to add after the launch of the headphones but I think a highly underrated feature of many headphones is SideTone. AKA the ability for the microphones to relay your voice back through into the headset so you don’t sound muted to yourself when making a call. This is so important of a feature to me that personally I don’t get headphones that don’t support this natively. (It keeps me from screaming because I can’t hear myself as well when wearing headphones lol)
Side note: As well as being an electronics technician I am a Audio/Video specialist. I have built some crazy systems in my day for companies like Chase, Goldman Sachs, LG… the list goes on. That being said I would like to point out ahead of time for those ready to comment : Transparency mode is NOT the same as SideTone. SideTone isolates your voice and relays it back to you so you hear yourself at a normal volume, where Transparency is all noises around you (Ex, other people, cars, background noise, etc). Also, yes Windows does support software SideTone however the latency is way to high and it causes some very annoying echos. SideTone has to be supported natively on the hardware of the headphones for it to work properly.
Like I said, I understand if it can’t be baked in after the fact, but I figured I would throw it out there since this is the first I hear of the very promising WYZE Headphones.
