HDMI Noise-Stopper

Plugged one into the empty HDMI port on my receiver and the background hiss I'd been blaming on my speakers just vanished. It's a small thing, but it fit snugly and didn't feel cheap like I worried it might. My setup finally sounds as clean as it looks.

My receiver has two unused HDMI inputs and I could always hear a faint hiss from the speakers with nothing plugged in. These caps seal those ports right up and the noise floor dropped to dead quiet. Simple little thing, but it fixed an annoyance I'd put up with for years.

Didn't think a little cap on a spare port would matter, but the buzz I kept hearing through my speakers is basically gone now. It fits snugly and the build feels solid, not like cheap plastic.
