The sound on my KAIY C52 Bluetooth Audio Receiver is cutting in and out; is this a defect?

Sound cutting in and out on the KAIY C52 is often caused by environmental factors or connection issues rather than a hardware defect. Before concluding the device is defective, please try the following troubleshooting steps based on the manual:Check the Wireless Range: Ensure your Bluetooth source device (phone, tablet, or laptop) is within the 33-foot (10-meter) range. Obstacles like walls, metal objects, or large furniture can significantly reduce this range and cause the audio to stutter.Reduce Interference: Move the receiver away from other wireless devices (such as Wi-Fi routers, microwaves, or other Bluetooth transmitters) that might be causing signal interference.Inspect the Cables: Ensure the 3.5mm AUX or RCA cables are pushed firmly into both the C52 receiver and your speaker system. A loose connection can cause intermittent sound. If possible, test with a different audio cable to rule out a faulty wire.Power Supply: Ensure the USB power cable is connected to a stable 5V power source. An inconsistent power supply can cause the internal Bluetooth chip to reset or drop the connection.Source Quality: Verify that the issue isn't with the streaming app or the audio file on your source device. Try playing music from a different app or device to see if the cutting persists.If the sound continues to cut in and out even when the device is right next to the receiver and you have swapped the cables, the unit may have a defect. In this case, you should contact KAIY customer service for warranty support.
