    If your audio source only has a 3.5mm (1/8-inch) headphone jack, you will need a high-quality 1/4-inch to 3.5mm adapter (not included). Connect the 1/4-inch plug of the headphones to the adapter, then connect the adapter to your audio source.

    Adjust the headband so that the earcups comfortably cover your ears. The soft ear pads are designed for extended listening comfort. Ensure a proper seal around your ears for optimal sound quality and bass response.

4. Instrucțiuni de utilizare

  1. Controlul volumului: Adjust the volume using the controls on your connected audio source. Start with a low volume and gradually increase it to a comfortable listening level. Avoid excessively high volumes to prevent hearing damage.
  2. Mediul de ascultare: While the TH900 offers some passive noise isolation, it is not designed for active noise cancellation. For the best listening experience, use the headphones in a quiet environment.
  3. Perioada de rodare: Like many high-fidelity audio components, the TH900 headphones may benefit from a "break-in" period. Initial sound characteristics may evolve slightly after several hours of use.

5. Întreținere

  • Cleaning Earcups and Headband: Gently wipe the ear pads and headband with a soft, dry, lint-free cloth. For stubborn marks, a slightly damp cloth with mild soap can be used, but ensure no moisture enters the driver units. Allow to air dry completely before use.
  • Cleaning Lacquer Housings: The Urushi lacquer finish is delicate. Clean the earcups with a very soft, dry cloth. Avoid abrasive materials or harsh chemicals, which can damage the finish.
  • Îngrijirea cablului: Avoid sharply bending or twisting the audio cable. Do not pull on the cable to disconnect the plug; always grasp the plug itself.
  • Depozitare: When not in use, store the headphones on the provided ST300 headphone stand to maintain their shape and protect them from dust and damage. Keep them in a cool, dry place away from direct sunlight and extreme temperatures.
