3.5mm Stereo Volume Controller, Headphones Volume Attenuator with Full Aluminum Alloy Case for Interference Isolation, 1/8-Inch Volume Inline Volume Control

So glad I bought this. It's heavy, solidly built and feels high quality. I've been using it for several months and love being able to gradually increase or decrease headphone volume. No static. I don't have a problem with this for my use case due to it's weight and tactile bottom but since it's small I can see where some may want to further secure it to a bench/table with double-sided tape. It is not powered, so it won't boost but it will adjust from off (mute) to maximum volume. The dial feels professional with a little resistance to it.

I run a PS5 into my main computer monitor with audio out from it into my speakers. PS5 output is MUCH higher than computer so when I switch between the two, the volume jump was awful. I've added this inline from monitor to speakers, allowing me to attenuate and match volume. Quality so far is great - well built, pot is very smooth and responsive, is exactly what I was looking for.

A wonderful device for a silly little specific use case. I do think you lose a bit of top end volume but that wasn’t a problem for my use case and I didn’t test it enough to warrant deducting a star but something to be aware of.

As you can see in the photo, this thing is indeed tiny. There are two rubber pads on the bottom which cover screws that hold the case together. I wanted to use double sided tape on the bottom so I removed the rubber pads, and seeing the screws, removed them as well just to see the build quality. Inside is a bit peculiar, as if someone soldered it in their lap while watching TV and eating popcorn. The head of the phillips screw on the far left was stripped as well, so I left it alone. The outside is very nice and it functions perfectly as a volume control. One star off for the inside, which I guess really doesn't matter.

Great build quality and sound

Read the fine print! I first connected the volume controller backwards (the print identifying the ports is really small) and the controller didn't work at all. When the cables were reversed, the volume controller worked great. No noise when turning the volume control either. Great little device!

Works like a charm, easy to carry around, highly recommend.

Seemed nicely built but it lowered the upper volume limit by a significant number of decibels. Did work for lowering volume to zero. But not having max volume available was unacceptable so I returned it.
