My mini ITX motherboard doesn't have as many USB ports as I'd like. I've also decided 2024 is the year I try to kill off all my USB micro devices and replace them with USB-C (sorry PS4 controller). So I'm going to go Bluetooth as much as it makes sense (because of the limited USB ports), and use devices that charge over USB-C

For communication during gaming over discord I've been using a Logitech g933 for about 8 years with the USB receiver, so that's on the chopping block.

I'm quite happy with the sound quality for music I currently get out of my Bluetooth headphones. A2DP gives a really great experience. Using those same headphones as a communication device with Discord for both recording and playing audio is really awful though as it kicks back to HFP/HSP. So I was wondering if it's possible to do a dedicated Bluetooth microphone? And more importantly: does connecting a micrpphone-only device over Bluetooth still need to be in the HFP/HSP profile to work?

To be clear: my goal is to be wires-free for my audio solution, while having both a high quality audio output to hear my beloved gaming companions AND to have a high quality (or at least clear quality) audio input so my beloved gaming companions can hear me. The microphone built into Bluetooth headphones is generally shit and sounds like being on a cell phone call from 1999, even when using it on an android or Windows machine that gave custom Bluetooth stacks that don't fall back to HSP. That's why I'm interested in using a dedicated high quality (probably condenser?) microphone, I'm just unsure if that high quality makes it back to the computer when connected through Bluetooth.

From the last couple hours of searching and reading I can only seem to find information regarding Bluetooth recording+playback combined headsets and the A2DP/HSP stuff. I can't seem to find anything about regarding dedicated microphones quality over Bluetooth.

You will not get good sound and microphone quality over Bluetooth. The best you will get is "decent" mic quality and mono audio that is only good for voice OR "decent" stereo audio and no mic. Not both at the same time. Stick with 2.4GHz or wired and just get a usb hub.

I don't want both at the same time.

I'm happy with my Bluetooth headphones doing just audio out with no mic.

I'm trying to figure out if I get a different dedicated Bluetooth mic, will it actually be decent mic quality over Bluetooth, or will it be the same garbage mic quality I get when coming from a headset+mic combo?

My wife was having trouble with audio quality during her endless Teams calls so I got her a gaming headset and it has worked wonderfully. I won't endorse one brand over another, but if you look the different models up you'll see that some boast about voice clarity in chat. This is what you are looking for if you need a good mic. My guess is that they are EQ'd for voice to be clear even during gameplay.

Yeah, my current wireless headset with a USB dongle has great quality for both sound and mic. But I have limited USB A ports on my motherboard, so I'm trying to move to purely Bluetooth to free up the USB port. Bluetooth sound output on a headset works fine, the only open question I have is Bluetooth sound input quality, because I can't find any useful information after a couple of hours of searching about dedicated microphone devices and their audio quality over Bluetooth.
