Anyone who can tolerate 40ms of latency should stick to Bluetooth. If it's more than 3ms, it's already more latency than a good RF system gives you, if it's more than 10ms things are getting questionable, and at 20+ms you've lost the ability to monitor, because what your fingers/voice do and what your ears hear are now noticeably out of sync. Try singing while monitoring yourself at 20ms delay. It's hilarious.
