The 7Hz Salnotes Zero IEMs are designed for comfortable and secure fit. They are intended to be worn with the cable routed over your ear.

  1. Insert the earpiece into your ear canal, ensuring a snug fit.

Regular cleaning helps maintain sound quality and hygiene.

  • Gently wipe the earpieces with a soft, dry, lint-free cloth.

  • Use a small, soft brush or cotton swab to carefully remove any earwax or debris from the earpiece nozzles. Be careful not to push debris further inside.

6.2 Cable Care

The detachable OFC cable is designed for durability, but proper care extends its lifespan.

  • Avoid sharp bends or kinks in the cable.
