Sorry, there was a problem. Please try again later.We're here to help with your JBL Wireless microphone. Feedback happens when the sound from the speakers is picked up by the microphone and is re-amplified and sent to the speakers again. It can help if the microphone is beside or behind the speaker, rather than in front. If you need more help, please reach out to our customer support.
