A selector routes one chosen signal path; it is not a Y-splitter that feeds two headphones at once, nor a mixer that combines sources. Check the plug type first: TRS carries stereo audio, while TRRS can carry stereo plus microphone. Passive boxes need no power but usually do not amplify; a volume knob attenuates or controls the selected headphone path only where the maker says so.

Sescom SES-AB-SWITCH 3.5mm Stereo Audio A/B Switch
A passive bidirectional selector with two 3.5mm TRS inputs and a center-off rocker. It switches between two stereo sources or, in reverse, two destinations; the center position mutes the selected path.

Sescom TRRS-AB Passive 3.5mm TRRS A/B Switch

- 3.5mm TRRS with ground switching
- 2-in-1-out or 1-in-2-out selector
- Headset and microphone-capable connector type

Rolls SS412 Passive Analog Stereo Audio Source Selector
A passive desktop source selector with four selectable stereo inputs, including one 3.5mm input, and one stereo RCA output. The front knob adjusts the level of the currently selected source; it is for line-level use, not a headphone splitter.
- Four selectable stereo inputs including 3.5mm
- Stereo RCA output and front level control
- Four-source selection
- No power required
- Output is RCA rather than 3.5mm
- Not for microphone TRRS headsets
SPRODIO MD21 3.5mm TRS A/B Switch
A passive 3.5mm stereo TRS A/B box with ground switching. It selects either of two line-level or headphone-level sources into one output, rather than summing them.
- 3.5mm stereo TRS ports
- 2-in-1-out passive A/B selection

- TRS and TRRS support
- Bidirectional 2-in-1-out or 1-in-2-out routing
- Microphone-capable TRRS option
- Independent ground switching
- No level knob
- Never use as a simultaneous splitter
3.5mm Passive Audio Selector with Volume Control
A passive bidirectional 3.5mm stereo selector that routes one input to either of two outputs, or two inputs to one output. Its volume knob controls the listening level on the selected path, while its one-key mute silences it.
- 3.5mm stereo, 2-in-1-out or 1-in-2-out
- Passive volume knob and mute button
- Useful for switching headphones and active speakers
- No external power
- Does not support 4-pole headset microphones
- Volume control does not make it an amplifier
Little Bear MC104 Pro 4-Way 3.5mm AUX Selector
A four-way 3.5mm AUX selector that can be connected as four inputs to one output or one input to four outputs, selecting one route rather than mixing all sources. It adds a selector control, volume control and mute function.
- Four 3.5mm stereo AUX paths
- 4-in-1-out or 1-in-4-out selected routing
- More than two selectable paths
- Volume and mute controls
- Not a mixer
- TRS stereo use, not a headset-mic selector
Buying tips
- Use a stereo TRS selector for music and a TRRS selector only when you need a headset microphone. A TRS cable will not carry the microphone return through a TRRS switch.
- A bidirectional selector can be wired as 2-in-1-out or 1-in-2-out, but it chooses one path. Use a mixer when sources must be combined, and a splitter only when simultaneous outputs are acceptable.
