## Customer feedback

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.
