3. Setup Instructions
Follow these steps to set up your HIFIMAN SUNDARA headphones:
- Unpacking: Carefully remove the headphones and accessories from their packaging.
- Connecting the Cable: Locate the two 3.5mm connectors on the headphone cable. Insert one connector into the port on the left earcup and the other into the port on the right earcup. Ensure they are securely seated.
- Connecting to Audio Source: Connect the other end of the headphone cable (the single 3.5mm jack) to your audio source (e.g., amplifier, digital audio player, computer). If your audio source requires a 6.35mm (1/4 inch) jack, use the included 3.5mm-to-6.35mm adapter.

4. Operating Instructions
The HIFIMAN SUNDARA headphones are designed for comfortable and high-fidelity listening. Follow these guidelines for optimal use:
- Wearing the Headphones: Adjust the headband so that the earcups sit comfortably over your ears, fully enclosing them. The hybrid headband design ensures even weight distribution for extended comfort.
- Volume Control: Adjust the volume using the controls on your connected audio source. The SUNDARA headphones feature a high sensitivity of 94 dB and an impedance of 32 Ohms, making them relatively easy to drive with various devices. However, for the best performance, especially with demanding audio, a dedicated headphone amplifier may be beneficial.
- Listening Environment: As open-back headphones, the SUNDARA provides a wide soundstage but offers minimal noise isolation. They are best used in quiet environments to fully appreciate their sonic capabilities.

5. Maintenance and Care
Proper care will extend the life and maintain the performance of your HIFIMAN SUNDARA headphones:
- Cleaning Ear Pads: The updated earpads are designed for comfort. Gently wipe them with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- Cleaning Headband: Wipe the headband with a soft, slightly damp cloth. Ensure no moisture enters the internal components.
- Cable Care: The headphone cable is detachable. When disconnecting, always grasp the connector housing, not the cable itself. Avoid sharp bends or excessive pulling on the cable.
- Storage: Store your headphones in a clean, dry place away from direct sunlight and extreme temperatures. Using a headphone stand or the original packaging is recommended to prevent damage.
- Water Resistance: These headphones are not water-resistant. Avoid exposure to liquids.
