4. Connecting Two Devices Simultaneously
The MONSTER D01 headphones support simultaneous connection to two devices without distinction between primary and secondary earphones. This allows you to use each earphone separately or connect them to two different phones for separate operations.

5. Wearing the Headphones
The D01 headphones feature a lightweight, non-ear design with ear hooks for comfort and stability. Gently place the ear hook over your ear, ensuring the speaker is positioned to direct sound towards your ear canal without entering it directly. This open audio design prevents swelling or pain, even during long listening sessions, and reduces sound leakage.

- The headphones deliver HIFI grade sound quality with pure original sound and on-site sound effects.

The MONSTER D01 headphones support volume control. Please refer to your connected device's instructions for adjusting volume, as the headphones themselves do not feature physical control buttons.
Making Calls

Waterproof Feature
The headphones are waterproof, making them suitable for various activities. However, avoid submerging them in water for extended periods or exposing them to high-pressure water jets.
Maintenance
- Cleaning: Use a soft, dry cloth to wipe the headphones and charging case. Do not use abrasive cleaners or solvents.
- Storage: When not in use, store the headphones in their charging case to protect them from dust and damage. Store in a cool, dry place away from extreme temperatures.
