The aggregate ratings lean positive, with five-star ratings forming the largest share, but three-star ratings also appear and the sample is small. With no written feedback supplied, these figures do not establish what users liked or disliked. They offer limited context for a single-transmitter USB-C microphone and should not be read as evidence of audio quality or compatibility.

Frequently asked questions

Which devices is the KM23 listed for?

The listing names smartphones and says the USB-C receiver can also work with compatible tablets and laptops. Check the device's USB-C audio and OTG support, as some phone models require OTG to be activated.

Can the receiver charge a phone while recording?

The listing says the receiver's USB-C port allows the recording device to charge during use. It does not specify charging speed or whether every compatible device supports this.

How long can the transmitter record on a charge?

The stated maximum is up to 8 hours, with a listed charging time of 1.5 hours. Treat these as manufacturer claims rather than independently verified results.

Is this a two-microphone system?

No. The listing identifies one receiver and one transmitter, so it is a single-transmitter setup.
