Weird sounds from my headphones.

[Someonewithproblem]

After I open OBS, my headphones produce a weird (buzzing?) sound. When I say something, when I listen to something (video/game). I don't know what is the problem.
I'm using a bluetooth headphones with mic (Connect IT Doodle CHP-0800)

Bluetooth is pretty well-known here to have lousy quality. Designed for a phone call, not broadcast. That might be your entire problem, or you might also be clipping. (too loud *somewhere* in the chain between air pressure at the mic and air pressure at your speakers)

Note: even if you're not using the mic at a given moment, simply having it configured is enough to switch the entire system to "phone mode". If you insist on using bluetooth headphones, then you can get better quality by deleting that mic entirely from your rig. Once nothing calls for it, regardless of whether *you're* using it or not, it might switch to "speaker mode", which is better quality.

Also note that those two modes often appear as different devices, and you only hear one at a time. So when you do switch modes, it may fall silent entirely until you switch your output to the other device.

It actually help, but what if I want to use that mic? Is there something I should do?

Don't. Bluetooth is just bad.

In fact, *anything* wireless carries a significant risk, even if it sounds and looks good. Always use a wire if at all possible, at every stage of the process.

For example, the entire reason that Bluetooth and WiFi are on 2.4GHz is because of microwave ovens. They run at that frequency, so nobody else wanted to have their radio gear there for fear of rampant interference. That hole was then filled with non-critical consumer stuff, which Bluetooth and WiFi both are. Your neighbor might not know that his shielding is bad, but you do!

Even for professional stuff, that runs at different frequencies, wireless is an automatic liability to be avoided if possible. Every wireless mic on stage, for example, has to be coordinated with *everything* else in the venue, not just mics, so that none of it interferes with each other. And even then, a rogue transmitter somewhere can still wreck everything. Or a metal structure that wasn't accounted for, etc.

Thank you.
