For anyone who has bluetooth issues with the 2018 mini, I noticed htat my Sony 1000x headphones worked like crap 1 foot form the mini but if I plug the magic trackpad 2 into the Mac lightning cable to constantly charge and run directly, the headphones work perfectly with good reception. I also use the LG untrained monitor so wasn't sure what was causing the static in the past. so im assuming the static is something to do with the new trackpad running on bluetooth. Also the trackpad would sometimes lose connection and then connect again within seconds to the Mac mini on bluetooth. The new magic numerical keyboard never disconnected. just expressing my testing if anyone is dealing with this. I dont mind having the trackpad plugged in since it holds the battery life.
