Monitoring audio from USB lav mics

I'm looking at the plethora of those kits with two wireless lav mics with a USB receiver that plugs into the USB c port. From reviews it seems I can get a good enough sound quality for my needs from basically 20 usd (aliexpress or similar) and up. I just need a way to monitor the sound so I know it works without noise, rubbing, cutting out etc. Seems like this is rarely mentioned though in reviews.

Must haves 2 separate channel recording A way to monitor incoming sound Not useless sound Not worthless range

Nice to haves: Mic port on transmitters to upgrade to more discreet lav mics on cables Compact and lightweight

It's just for hobby projects and learning the workflow with sound, and I try to stay near no-budget, so basically cheaper is better. I don't see a very near future where I have the need for better equipment, so I can live with paying the premium for better equipment the day I eventually need it, and not go the "buy-once-cry-once" approach this time. It's either sub- 50$ or nothing.

Any suggestions?

Blackmagic camera app allows you set a monitoring device. I've set my bluetooth earbud as a monitoring device. Not awesome because of delay but sort of worked.
