USB-C to 3.5mm Headset Adapter

One Adapter, Countless Classroom Uses

The USB-C to 3.5mm Headset Adapter makes single-plug TRRS (CTIA) headsets—with microphones—work on USB-C devices. It reliably converts digital↔analog audio for clear playback and voice capture, so students can join assessments, language labs, and read-alouds without changing headsets.

Why schools choose it

• Mic-capable TRRS (CTIA): Supports headsets with a single 3.5mm plug (audio + mic), not just audio-only earbuds.
• Clear voice pickup: High-quality A/D conversion helps speech sound accurate for apps and recordings.
• In-line control support: Android: Play/Pause + Vol Up/Down; Apple (USB-C): Play/Pause.*
• Fleet-friendly: Standardize rooms that moved from 3.5mm to USB-C—no need to rebuy headsets.
• Classroom-durable: Short, braided tail helps reduce strain at the device port.

*Exact button behavior can vary by device/app.

Compatibility

• Devices: Chromebooks, laptops, and tablets with USB-C ports (including many iPads).
• Headsets: Single-plug 3.5mm TRRS (CTIA) headsets with microphones.
• OS: Windows 10/11, Android, and most Apple devices with USB-C ports.

Fast setup

1. Plug the adapter into the device’s USB-C port.
2. Connect the single-plug TRRS headset.
3. Select the adapter as both Input and Output in the OS/app.
4. Run a 10-second mic test (watch the input meter).

Troubleshooting tips

• No mic input: Grant mic permission to the app; reselect the adapter as the input device.
• One-ear audio: Fully seat the 3.5mm plug; confirm CTIA wiring; try another port.
• Inline buttons not working: Behavior varies by OS/app; Play/Pause is most universal.
