Operating Instructions
Controls Overview
The headphones feature intuitive touch controls and physical buttons. Refer to the quick start guide for a detailed diagram of button functions.
Adaptive Active Noise Cancelling (ANC)
The headphones automatically detect ambient noise levels and adjust the noise cancellation intensity. This feature effectively reduces surrounding noise while minimizing the feeling of pressure, ensuring comfort during long listening sessions.

Ambient Sound Mode
Use the dedicated "MyTune" app to select and incorporate external sounds. This allows for "listen-through" functionality while commuting or in the office, and enables calls while remaining aware of your surroundings.

Voice Noise Cancelling (Voice Chamber)
The "Voice Chamber" technology, developed using AI-learned language pronunciation data, ensures your voice is clear during calls even in noisy environments. Five built-in microphones analyze the surrounding sound.

TailorID 2.0 Sound Customization
The unique "TailorID 2.0" function tests how each ear perceives sound frequencies independently and automatically adjusts to optimal sound for each individual. This provides precise sound adjustment tailored to your ears.

Troubleshooting
- No Power: Ensure the headphones are charged. Connect to a power source using the USB-C cable.
- No Sound:
- Check if the headphones are properly paired via Bluetooth or connected via AUX cable.
- Adjust the volume on both the headphones and your connected device.
- Ensure the audio source is playing.
- Poor Sound Quality:
- If using Bluetooth, ensure you are within range of your device.
- Disable LDAC in the MyTune app if you are experiencing issues with other features like multipoint or surround sound, as LDAC can sometimes limit these.
- Use the TailorID 2.0 feature in the MyTune app to optimize sound for your ears.
- Noise Cancellation Ineffective:
- Ensure the ear pads form a good seal around your ears.
- Check ANC settings in the MyTune app.
- Cannot Connect to Two Devices (Multipoint):
- Ensure multipoint is enabled in the MyTune app.
- LDAC codec may disable multipoint. Switch to AAC or SBC if multipoint is desired.
- Wired Connection Issues: When using the 3.5mm AUX cable, ANC and app-based sound adjustments are typically disabled. This is normal operation.
