Need help with wireless

Hi everyone. Newbie here. I just got my first pair of IEMs along with wireless receivers. I know a lot of people don't like wireless sound, but I have found that sacrifice to be worth it for mobility. My KZ-ZS PRO X buds, with theKZ-AZ09 Bluetooth receivers are better on my phone than anything I have ever owned in my life. Now I need to connect it to the computer, but I don't have wireless on my pc.

I am looking into Transmitter/Receivers on Amazon in the $20 range. It has to be 5.4 and long range. I know the claims of "500 feet" have to be exaggerated, but I do need to get good range if I can, without sacrificing any more sound if I can help it.

I would like to be able to link my other pc devices (keyboard, mouse, etc.) into one Bluetooth hub unless it hurts the sound quality even more.

I don't know if there are other considerations that I am missing with IEMs specifically. These are my first IEM's as well as my first serious wireless adapter for them
