3.1 Connecting the Audio Cable

1. Locate the audio input jack on the left earcup of your Ultrasone PRO 900 headphones.
2. Insert the smaller end of the provided audio cable (3.5 mm jack) firmly into the headphone jack until it clicks into place.

3.2 Adjusting for Comfort

For optimal sound and comfort, adjust the headphones to fit your head properly:

• Extend or retract the headband sliders on both sides until the earcups comfortably cover your ears.
• Ensure the earcups sit flush against your head to maximize sound isolation and bass response.
• The earcups are designed to swivel for a flexible fit and easy single-ear monitoring.

4. Operating the Headphones

4.1 Basic Usage

Once connected to an audio source, begin playing your desired audio. The Ultrasone PRO 900 headphones feature S-Logic technology, which aims to provide a more natural, speaker-like listening experience by utilizing decentralized driver positioning. This technology also helps to reduce sound pressure on the eardrum, potentially allowing for longer listening sessions without fatigue.

4.2 Volume and Media Control

Volume and media playback are typically controlled directly from your connected audio source. The headphones themselves do not feature integrated volume or media controls.

5. Maintenance

Proper maintenance ensures the longevity and performance of your Ultrasone PRO 900 headphones.

5.1 Cleaning

• Ear Pads: The ear pads can be removed for cleaning or replacement. Gently wipe them with a soft, damp cloth. Avoid harsh chemicals.
• Headband and Exterior: Use a soft, dry, or slightly damp cloth to wipe down the headband and exterior surfaces. Do not use abrasive cleaners.
• Connectors: Keep the audio cable connectors clean and free of dust.

5.2 Storage

When not in use, store your headphones in the provided protective transport box to prevent dust accumulation and physical damage. The foldable design allows for compact storage.

5.3 Cable Care

Avoid sharply bending or twisting the audio cable. Always grasp the connector, not the cable itself, when plugging or unplugging. Replace damaged cables promptly to maintain audio quality.

If you encounter issues with your Ultrasone PRO 900 headphones, refer to the following common solutions:
