Hello! As I mentioned in the review, the volume of the sidetone is pretty subtle, and there’s no apparent way to turn it on or off.

On my headset, it’s active whenever the mic is flipped down and un-muted. I notice it most when I’m moving my fingers over the end of the mic or when I really “eat the mic” with my mouth. But it’s definitely there.

You should be able to test it out with no mic audio or chat audio going, just by rubbing your fingers over the mic hole or by really getting up in the mic’s business with your voice.

If you still can’t hear it, it’s possible you have a defective unit. At that point you’ll have to contact Plantronics support, because I’m just a guy that bought these like you.

The fact that they didn’t include adjustable sidetone volume (or adjustable mic volume in Windows) is one of the only things I don’t like about the RIG 800 LX. If they insist on having it turned on all the time, I’m actually glad the volume isn’t that intense.

I still use mine on a pretty regular basis, but mostly with my PC. And because of the holidays/other reviews, I haven’t touched mine in about two weeks. I suppose there’s a remote possibility that they pushed some kind of firmware update that turned off the sidetone, but I don’t think that’s very likely.

Thanks for reading!
