• Check that the transmitter is correctly paired with your headphones/speakers and the appropriate audio codec is active (indicated by the LEDs).
• If experiencing static or noise, try moving the transmitter away from other electronic devices, power outlets, or Wi-Fi routers, as electrical interference can affect audio quality.
• Ensure your receiving device supports the same high-quality codec as the transmitter for optimal audio performance.

قضايا الاقتران:
