I sit at a soundboard control wire connected to a distribution panel 30 feet away. The VC20 gives me the volume control I so desperately need.

Worked so well I ordered a second one.

My husband had a game console that he wanted to play through his large LCD panel with an audio output. When he played the game it drove me crazy with the sounds. I asked him to plug in his headphones, but the headphones he had were very loud since they had no volume control on the phones.

The KOSS volume control was a very inexpensive solution to the issue.

As a side note I can also use it to control the input volume of a microphone I have.

Purchased this VC20 for the Monsoon MM-700 computer speakers that I have that are 20 years old. The “puck” that comes with those speakers finally failed completely and the VC20 is the ideal replacement part. Just needed another 3.5mm cable to go from speakers to the volume control. Thanks!

could use a mute feature but works well between tv and ear buds
