Koss 155954 VC20 Volume Control, Standard Packaging, 39-Inch Cord, Compatible with Cell Phones and Headphones

It works fine as volume controller , but if you wish use it with a mic for signal attenuation, it wont work properly. It suppresses the signal greatly

I use a radio, a Sony ICF-7600GR, that is a little "hot" on the audio output jack. Even with radio volume at minimum the sound level was too loud for my mono earphone. I listen to AM radio stations overnight with that earphone, so it was critical to reduce the volume to a level that was still audible, but not distractingly loud.This unit arrived today and I tested it immediately. It works perfectly, and I now have much more control over the volume level. I presumed it would work OK with mono, even though it is made for stereo - and it works great.Very happy with this purchase. Koss is a quality brand. It's maybe a lot of money for a simple potentiometer - but the build quality made it worthwhile.

Bastante contento con su funcionamiento, no me molestaría pagar un poco mas por algo con materiales Premium (Pero este se veía como la mejor opción) pero es bastante buena, cumple y no introduce ruido.

To have loud or soft sound volume, without this it can be difficult

全てにおいて、私のアンテナが受信w音質、音圧、高音、低音のキレ言う事なし。ノイキャンはダイヤル、アナログ感むき出しのデザイン、機能いゃ〜購入してよかったです！

Arrived in a timely fashion, as described in description - would recommend to would be purchasers - good product overall. In my case for night listening ipod classic low volume to loud - with these the volume can go right down - brilliant!!
