In-line volume controller for 3.5mm headphones

The Koss 164210 is a passive in-line volume controller finished in titanium grey. It inserts between a 3.5mm stereo headphone jack and the headphones themselves, giving immediate level adjustment via a built-in slider. A pocket clip is included for securing the unit to clothing or a bag strap.

Suits listeners who want hardware level control

Ideal for anyone using headphones with a 3.5mm plug who prefers a tactile slider over software or source-side controls. The 39-inch cord adds reach without requiring an extension cable. Buyers whose headphones use a proprietary connector, USB audio or a different jack size will need a separate adapter before this controller can be used.

3.5mm connector compatibility is the deciding

The controller accepts and passes through a standard 3.5mm stereo connection only. Verify that both the source jack and the headphone plug match this size; other connector types will not fit without an adapter.

Questions about this item

What does the 3.5 mm connector on this Koss 164210 volume controller plug into?

It plugs directly into any 3.5 mm stereophone jack on your audio source, letting you adjust the level right at the cord without reaching for the device.

How long is the cord and what clip is supplied for mounting?

The cord measures 39 inches and a pocket clip is included so you can fasten the controller to clothing or a bag strap.

How do I install the VC20 in-line controller and what step do people often miss?

Insert the controller's 3.5 mm plug into the source jack, then plug your headphones into the controller; the step often missed is ensuring both connections are fully seated so the volume control works across the entire range.
