Headset

[lostsoul62]

I bought these 6 years ago and hardly used them
C2G/Cables to Go Audio Unlimited 900MHz Wireless Rechargable Stereo Headphones (SPK-9100)
I'm getting a humming sound when I watch TV. Do I need a different headset or am I doing something wrong?

Does the humming sound appear on other devices?

It may just be interference.
