Regardless of listening to music or video, I'm experiencing intermittent static while plugged into my office iMac. The static noise is every few seconds, but there is no consistent timing between noises. I moved the cable away from other electronics and power cords to no avail. Muting audio does not prevent noise. The headphones are Audio-Technica ATH-M40x and the computer is an iMac running High Sierra 10.13.6
I also plugged the headphones into my MacBook Pro (also running High Sierra 10.13.6) and the static ceased, so the headphones are fine?
