I had mistakenly assumed that the receiver would act as a USB microphone, but no; the USB is for charging only. You have to connect the receiver and a microphone port using the supplied jack cable. Audio quality is in most cases good (but sometimes remote listeners complain of a high-pitched background noise that goes away if I switch to a different microphone); battery life is so-so (the microphones only last 3-4 hours before needing to be charged). Having two microphones this isn't a big deal as I can switch to the other while one charges. Pairing works seamlessly, but I wonder what would happen if several of these senders and receivers were used within range of each other. Speaking of range, that at least seems to be a non-issue; I think you could wear one of the mikes and walk around an auditorium without losing the connection to the receiver. (A stadium would be pushing it, though. :) I wasn't able to use these microphones in a loudspeaker setup with a Tronsmart Halo speaker, but it's possible my jack cable is broken. On the whole this product is far from terrible but is also not great. I don't regret buying it, but wouldn't unconditionally recommend it.

The voice recording quality of the product is excellent, and the original mode is quite stable. However, in the noise reduction mode, the voice feels like it loses a frequency, but overall, for the price, it's more than good enough to buy.
