WLTASUY 3.5mm Bi-Directional Audio Switcher 2-in-1/1-in-2 Out Black

Compact bidirectional 3.5 mm audio switch

This passive switcher lets you route stereo signals between two sources and one output or one source and two outputs with a single button press. It is built for desktop users, gamers and mobile listeners who want to swap headphones, speakers or soundbars without unplugging cables. The aluminium shell measures 2.6 by 2.5 by 1.1 inches and draws no external power.

Passive operation with silent switching

Because the unit requires no power supply it adds no noise, heat or standby draw to the signal chain. The mechanical selector toggles instantly and silently, preserving audio fidelity across all connected 3.5 mm devices. A 3.3‑foot auxiliary cable is included for immediate setup.

Two‑way routing for one‑to‑two or two‑to‑one setups

The bidirectional architecture supports either 1‑in‑2‑out or 2‑in‑1‑out configurations, so you can send one source to two listening devices or switch between two sources into a single speaker or headphone. It does not split a signal to both outputs simultaneously.
