UGREEN 80864 USB-A to 3.5mm TRRS Sound Card

Overview

UGREEN 80864 is a compact USB-A external sound card that adds one 3.5mm CTIA TRRS headset connection for stereo playback and compatible microphone input. This guide uses the exact active Shopify record, every meaningful product-owned gallery image and exact UGREEN evidence to keep direction, connector, sample-rate, microphone, power and compatibility claims revision-specific.

Exact product role

a compact USB-A external sound card that adds one 3.5mm CTIA TRRS headset connection for stereo playback and compatible microphone input.

Signal path

USB-A connects to the computer or supported console host. Digital playback is converted to analogue stereo at the 3.5mm jack, while a compatible TRRS headset microphone is converted back to USB input. The single socket is a combo headset port.

Conversion boundary

Exact UGREEN evidence specifies playback output up to 24-bit/96kHz and microphone input up to 16-bit/48kHz using the ALC4030 chipset. The OS, console and application may negotiate lower settings.

Power design

USB bus-powered with no battery or external supply. It is not a charging adapter and does not power passive speakers.

USB-A connects to the computer or supported console host. Digital playback is converted to analogue stereo at the 3.5mm jack, while a compatible TRRS headset microphone is converted back to USB input. The single socket is a combo headset port.

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.

Source recording, operating-system mode, app processing, cable path, gain staging and destination equipment all affect the heard or recorded result. A format ceiling is not a promise of better sound from every source.

1. Step 1: Connect a CTIA TRRS headset fully to the 3.5mm socket.
2. Step 2: Insert the sound card into a working USB-A host port.
3. Step 3: Select the UGREEN/USB audio device for both playback and recording.
4. Step 4: Set a low playback level and test left/right audio.
5. Step 5: Test the microphone in system settings before opening the game or meeting app.

Usability tip: test playback and microphone or charging separately before relying on simultaneous operation.

USB-A hosts with standard USB audio support, including listed Windows and macOS computers, Chrome OS, Raspberry Pi and PS5/PS4. Linux may require additional configuration or driver support. Not for TV, car audio, Xbox, PS3, Wii or Wii U.

• Match the exact 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.

Confirm exact SKU

Check 80864 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.

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 exact 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 behaviour: USB bus-powered with no battery or external supply. It is not a charging adapter and does not power passive speakers.

• 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 exact IP rating is published.

No playback

Check source output selection, destination input, mute state, volume and full connector seating.

No microphone

Confirm an exact 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 exact operating-system support.
