Bluetooth was not originally designed or specced to be low latency. Bluetooth 5, under ideal conditions, can noow manage 20ms, 40 is more likely. The aptX codec aims to keep under 40ms.
If you're just listening to music then 100ms might be OK, as there is no reference visual clue to give you problems. For direct speech then 40ms is regarded as the max most people find acceptable.
If this is OK for you and your playing, and your hearing aids support this, then inbtheory you're good to go.
But bear in mind there will be another 20-40-80ms delay from whatever is encoding the signal from the sound desk, and that will cause the problem.
