If needed, try using a different device to determine if the problem lies with the headphones or the original audio source.

How can I clean and maintain my Sennheiser HD 300 PRO headphones?

Regularly clean the ear pads with a damp cloth and mild soap. Avoid using excessive moisture. For the headband and outer parts, use a dry cloth to wipe away dust and fingerprints. Store the headphones in a protective case when not in use to prevent damage.
