Setup Instructions

  1. Connect Headphones: Plug your 3.5mm headphones or earphones into the 3.5mm audio jack of the AUDIOCULAR SPARK dongle.
  2. Connect to Device: Insert the USB-C connector of the AUDIOCULAR SPARK dongle into the Type-C port of your smartphone, tablet, or notebook.
  3. Automatic Recognition: Your device should automatically recognize the dongle as an external audio output device. No additional drivers are typically required for most operating systems (Android, Windows 11).
  4. (Optional) USB-A Connection: If connecting to a device with a USB-A port (e.g., a laptop), use the included USB Adapter (Type-C to Type-A) to connect the dongle. The necessary drivers should install automatically.

Operating Instructions

The AUDIOCULAR SPARK operates as a plug-and-play device. Once connected, your audio output will be routed through the dongle to your 3.5mm headphones.

  • Audio Playback: Begin playing audio from any application on your connected device. The sound will be processed by the SPARK's DAC and amplifier, then output to your headphones.
  • Volume Control: Use your device's native volume controls to adjust the output level.
  • High-Resolution Audio: For optimal high-resolution audio playback (PCM 32bit/384kHz), ensure your audio files and playback software support these formats. On Android, third-party apps like USB Audio Player PRO or Poweramp may be required for bit-perfect or hi-res output.
  • Impedance Compatibility: The dongle is compatible with headphones ranging from 16 to 320Ω impedance. It delivers 63mW output at 32Ω.

Maintenance

  • Cleaning: Use a soft, dry cloth to wipe the dongle. Avoid using liquid cleaners or solvents.
  • Storage: Store the dongle in a cool, dry place away from direct sunlight and extreme temperatures.
  • Handling: Handle the dongle by its connectors when plugging or unplugging to avoid stressing the cable. Do not pull on the cable itself.
  • Protection: While durable, avoid bending or twisting the cable excessively to prevent internal damage.

Troubleshooting

Problem Possible Cause Solution
No sound output.
  • Loose connection.
  • Incorrect audio output selected on device.
  • Device volume too low or muted.
  • Incompatible device.
  • Ensure the dongle and headphones are securely plugged in.
  • Check your device's audio settings and select the AUDIOCULAR SPARK as the output.
  • Increase device volume and check for mute settings.
  • Verify your device has a functional Type-C port and is not a Moto Series phone.
Poor sound quality or distortion.
  • Low-quality audio source.
  • Damaged dongle or cable.
  • High impedance headphones requiring more power.
  • Use high-quality audio files (e.g., FLAC, WAV) for best results.
  • Inspect the dongle and cable for visible damage.
  • While the SPARK supports up to 320Ω, very high impedance headphones might benefit from a dedicated, more powerful amplifier.
Microphone issues during gaming (sound suppression).
  • Specific software/game interaction.
  • This can be a known issue with certain games (e.g., BGMI) where game sound is suppressed when the mic is active. This is often a software-side limitation. Consider using an alternative audio solution for gaming if this issue persists.
Dongle not recognized by device.
  • Device incompatibility.
  • Faulty Type-C port.
  • Ensure your device is compatible (not Moto Series).
  • Try connecting the dongle to another compatible device to rule out a faulty port.
  • If using a USB-A adapter, ensure it is functioning correctly.
