Please understand that wireless technology is always susceptible to interference and/or signal loss.

In certain circumstances, a signal from another device, like a cordless phone (DECT), cell phone, wireless network (Wi-Fi), or wireless video transmitter (TV-Link) can create static or noise in the reception of your headphones.

This is especially true when the other device is operating at the same or similar frequency.

Solution: Try relocating the position of the interference source.
