AXAGON ADA-HA USB-A to 3.5 mm Audio Adapter Hi-Res DAC 384 kHz / 32-bit Stereo

AXAGON ADA-HA is a compact USB-A to 3.5 mm audio adapter with an integrated Hi-Res DAC that supports up to 384 kHz/32-bit stereo. The device converts digital audio from a computer or other USB-A source into analogue output for headphones or line-level inputs, providing a simple way to achieve higher quality playback without opening the computer or installing an internal sound card. The adapter is intended for desktop and portable use and fits standard 3.5 mm headphone jacks.

Advantages

The adapter offers native Hi-Res digital-to-analogue conversion up to 384 kHz/32-bit in stereo, improving clarity and reducing noise compared with typical onboard audio. Its USB-A connection requires no external power supply and works as a plug-and-play device on compatible systems. The small form factor and standard 3.5 mm output make it compatible with most headphones, powered speakers and line inputs for easy integration with existing audio setups.

Suitable for

• Upgrading laptop or desktop audio without installing internal hardware
• Connecting headphones to a USB-A port for improved sound quality
• Feeding analogue line-level inputs of powered speakers or amplifiers
• Portable use with computers and devices that support USB-A audio output

When it may not be suitable

The adapter requires a device with a USB-A port that supports USB audio class; some older or locked-down systems may not provide full driverless compatibility. It does not provide separate microphone input or multiple outputs and is limited to a single stereo 3.5 mm analogue output. Users who need balanced outputs, multi-channel analogue outputs or professional audio interfaces should consider more advanced external DACs or audio interfaces.

Key specifications

• Digital-to-analogue conversion: Hi-Res DAC supporting up to 384 kHz sampling rate and 32-bit depth in stereo
• Connector: USB-A input and 3.5 mm TRS analogue output
• Output type: Headphone/line-level stereo analogue output
• Power: Bus-powered from USB-A port (no external power required)
• Form factor: Compact inline adapter designed for desktop and portable use

How to use

Plug the AXAGON ADA-HA into a free USB-A port on your computer or compatible device; the operating system should detect the adapter as an audio output device. Select the adapter in your system or application audio settings as the output device. Connect headphones or the analogue input of powered speakers using a standard 3.5 mm stereo cable. Playback of high-resolution audio files will be handled by the adapter’s internal DAC up to the supported sample rate and bit depth.

What to consider before purchase

• Ensure your computer or device has a USB-A port and supports USB audio output
• Confirm that a single stereo 3.5 mm output meets your connection needs (no mic input or multi-channel outputs)
• Check whether your operating system requires specific drivers for advanced sample rates
• Verify headphone or speaker sensitivity and impedance to ensure suitable volume and sound quality

Usage recommendations

For best results, use high-quality headphones or powered speakers and select the adapter as the primary audio output in your operating system. When playing Hi-Res files, confirm your audio player is configured to output at the file’s native sampling rate and bit depth to utilize the adapter’s full 384 kHz/32-bit capability.
