Feedback in USB Headset?

Ok, this is really annoying. My headset has been working great for months. Today I was on a video conference call and I was hearing myself talking. Usually when that happens, its because someone else on the meeting is using their PC speakers so everything I say feeding back through their speakers into their microphone. I said to the lady on the phone, can you please turn off your speakers and she said she couldn't because she didn't have a headset.

Well, maybe it wasn't her anyway. Some reason even now.. I'm not on a video call. My headset is just sitting there next to me unused. But, as loud noises happen, I can hear it clearly coming out of the headset's speakers. My speakers to the PC are off. I restarted the PC to make sure all the programs that use the headset were closed. It's still doing it. And, with the headset just sitting there, I can hear a weird ringing noise (not really a ringing... not sure how to describe it other than weird feedback) coming out of the earpiece every minute or so. It's baffling me.

Do you have your headset plugged in right into the computer?

I once have had a similar porblem. It occured because of the power that's running through the usb port. I used a usb hub and something was off with it.

No, it is plugged in directly into a USB port on the laptop.

Is there a mic on this headset?

Yes, the headset has a mic. I jjst remembered a little bit ago I had a spare usb headset. I switched to that one and it works just fine. The logitech headset is significantly more expensive. The one I replaced it with were some cheap ones I got off of amazon for rhe kids to use with their chromebooks.

What you're hearing is feedback between the usb head set mic and the earphones... Either switch off the mic on the headset (if possible) or fade it down (or switch off/disable) in audio settings?

If none of the above are possible or don't work then there is problem within the wiring etc. of the mic - headset combination; and likely that's not (easily) repairable.

I found a different usb headset and tried it and it worked without any issues. The one that failed is a much more expensive headset though.

The expensive headset probably has more sophisticated circuitry
which amplifies the signal when the sound level into the microphone
is low, and limits the signal when the sound level is high. With very
little ambient sound, you could get a high level of amplification.

Here's a wild guess: Just before this problem began, did you turn
off noise cancellation? Does the Logitech headset have noise
cancellation? If so, I suspect that it was working until the problem
began.

Another wild speculation: Check to see that the microphone is clean
and not blocked by dust, gunk, food, scotch tape, chewing gum, or
whatever. If there are separate microphones for noise cancellation,
check that they are not blocked. The holes for the microphones may
be very small.
