Top critical review
Great audio playback, very poor microphone/phone call performance
Reviewed in Australia on 25 October 2018
Good: automatic connection to the phone works well, audio playback is of a very high quality.
Bad: whenever I'm on a phone call, the person on the other end says they have a really hard time hearing me. I am usually forced to switch my phone to the internal phone microphone so that I can be understood.
UPDATE: Nulaxy sent me a replacement device, believing that my device may have been faulty. However, the replacement device has exactly the same microphone quality issues. For reference, my KM24 is being used in combination with a Pixel 2 phone in a 2010 Model Hyundai i30 hatchback.
