Overview
- CTIA TRRS FEMALE • DUAL PC PLUGS • 20CM
What it does well.
Key features
What it does. a passive 20cm headset-to-PC adapter that separates one CTIA TRRS headset connection into dedicated 3.5mm headphone and microphone plugs for a computer with two audio sockets.
Signal path. Connect the headset’s four-pole CTIA plug to the single TRRS female socket. Connect the headphone-marked male plug to the computer’s audio output and the microphone-marked male plug to its microphone input. The adapter is not designed for reverse use.
Conversion boundary. There is no DAC, amplifier or format conversion. The cable passively routes analogue stereo playback and mono headset-microphone contacts. Sound quality and microphone level remain dependent on the headset and computer sound hardware.
Power design. No battery, charger or USB power. It carries low-level analogue headset signals only.
Signal direction and connector roles
Connect the headset’s four-pole CTIA plug to the single TRRS female socket. Connect the headphone-marked male plug to the computer’s audio output and the microphone-marked male plug to its microphone input. The adapter is not designed for reverse use.
Connector rule: an output must feed the matching input. Physical fit does not prove electrical role, microphone wiring, charging protocol or signal level.
Safe start: lower volume or gain, check labels and connect one complete path before adding any charger, second endpoint or application.
Conversion, sample rates and sound behaviour
Microphone, calls and controls
Microphone / call path. The microphone path requires a CTIA-standard TRRS headset and a working computer microphone input. OMTP wiring, proprietary inline controls and non-headset microphone power requirements may not work.
Controls. No controls. Headset buttons may not be interpreted by a two-socket PC because the adapter separates audio and microphone contacts but does not emulate phone remote electronics.
Use scenarios
Scenario 1. Using a mobile-style CTIA headset on a desktop PC.
Scenario 2. Voice calls on a computer with separate sound sockets.
Scenario 3. Gaming voice chat where the PC exposes separate audio and mic ports.
Scenario 4. Online classes with one four-pole wired headset.
Scenario 5. Replacing colour-coded breakout capability on an older laptop.
Setup and usability guidance
Usability tip: test playback and microphone or charging separately before relying on simultaneous operation.
- Step 1: Turn computer and app volume down.
- Step 2: Insert the headset TRRS plug fully into the adapter’s single female socket first.
- Step 3: Connect the headphone-marked male plug to audio out.
- Step 4: Connect the microphone-marked male plug to microphone in.
- Step 5: Select the computer playback and recording devices, then test sound and microphone separately.
Compatible devices and systems
CTIA four-pole headsets/earphones at the female end and PCs or laptops with separate 3.5mm headphone-out and microphone-in sockets at the two male ends.
- Match the connector role and wiring standard.
- Check host operating-system audio settings and app permissions.
- For USB audio, confirm the port supports data/audio rather than charging only.
- For analogue audio, confirm input versus output and headset TRRS versus stereo TRS.
- For XLR, confirm signal level, balanced wiring and phantom-power requirements.

- Do not infer microphone, charging, data, phantom-power or console-chat support merely from a connector fitting.
- Do not connect wet equipment or leave cables where they create a trip, snag or vehicle-control hazard.
- Do not use consumer/headset audio connectors with mains, speaker-level or unknown industrial signals.
What to do
Confirm SKU. Check 10790 on the product or package before relying on these specifications.
Start at low level. Lower headphone volume, speaker level, microphone gain or channel fader before connection.
Test one path. Verify one source, adapter/cable and destination before adding more equipment.
Keep ports clean and dry. Disconnect power, remove lint without metal tools and allow complete drying before reuse.
Use system settings. Select the intended playback and recording devices; physical connection alone may not change routing.
Store without stress. Coil cables loosely and protect exposed plugs, pins and adapter housings.
What not to do
Do not force a fit. Stop if alignment, case clearance, pins or latch do not match.
Do not guess direction. Inputs and outputs can share the same connector shape.
Do not overstate formats. Use only the sample-rate or signal claim listed for this SKU.
Do not use at unsafe volume. High playback levels can injure hearing and overload equipment.
Do not patch live phantom power. For XLR, mute and disable phantom power before changing connections.
Do not create hazards. Keep leads away from pedals, controls, doors, wheels, children and walkways.
Power, charging and operating conditions
Power behaviour: No battery, charger or USB power. It carries low-level analogue headset signals only.
- Use only compliant, undamaged hosts, chargers and cables.
- Disconnect for unusual heat, smell, intermittent power, corrosion or visible damage.
- Do not cover adapters during charging or operation.
- Keep all contacts dry and free of conductive debris.
- No product in this batch should be treated as weather-resistant unless an IP rating is published.
Warnings and limitations
- Hearing: begin at low volume, limit exposure and stop if you notice discomfort or ringing.
- Electrical: never connect audio pins to mains, unknown industrial wiring or incompatible high-power outputs.
- Microphones: mute channels before plugging; for XLR, switch phantom power only when the connected microphone requires it.
- Driving: connect and configure vehicle audio while parked; do not route cables across pedals, steering or airbags.
- Water and heat: keep connectors dry and away from hot dashboards, heaters and direct sun.
- Mechanical: do not pull by the cable, close doors on leads or leave adapters protruding where they can be struck.
Troubleshooting
No playback. Check source output selection, destination input, mute state, volume and full connector seating.
No microphone. Confirm an mic-return path, correct TRRS/XLR wiring, recording-device selection and app permission.
Charging absent or slow. Confirm that this SKU supports charging, then test a compatible charger/cable and inspect host limits.
Noise or hum. Separate signal leads from power bricks, test another port/path and verify balanced grounding or AUX input role.
One channel missing. Reinsert the plug fully, inspect contacts and test each device with a known-good cable or headset.
USB device not recognised. Try a direct data-capable USB port, reboot audio services and check operating-system support.
