  • No power supply needed — just plug in and use immediately
  • Metal CNC casing measures 2.1 inches wide for a compact desktop footprint

What this audio switcher does

The 3.5 mm stereo audio switcher routes analogue signals between two sources and two playback devices in a single metal enclosure. It operates without external power, making it suitable for desktop users who alternate between headphones and speakers or between a computer and a mobile device.

Signal quality under continuous use

A low-impedance design preserves high-fidelity reproduction during extended listening sessions while keeping cable-induced noise to a minimum. Gold-plated contacts on the headphone jack maintain consistent conductivity so the signal path remains stable even after many switching cycles.

Installation and common pitfalls

Plug the included 1 metre cable and your 3.5 mm devices into the labelled ports, then toggle the metal selector rod to change routing — no drivers or configuration are required. The unit does not pass microphone signals, so headsets that rely on a combined four-pole connector for chat will lose that function.

Questions about this item

Does the passive 3.5 mm switcher add any noise or heat when left connected all day?

No, it draws no power and has no active circuitry, so it generates no heat or electrical noise during continuous use.

What cables or connectors must I already have to use the 3.5 mm switcher with my PC and speakers?

You need 3.5 mm stereo cables for each source and each playback device; one 1-metre cable is included, the rest are not.

Will the 3.5 mm selector work with older three-pole headphone plugs and four-pole headset plugs I still own?

Yes, it accepts both three-pole and four-pole 3.5 mm plugs, though microphone contacts on four-pole plugs are not connected.
