Wipe with damp cloth and mild soap. Avoid strong solvents or submerging in water.

Wipe cushions clean but don't soak them. Replace if they become damaged or won't clean properly.

Weekly for regular use, or after exposure to excessive sweat, dirt, or chemicals.

Avoid alcohol, solvents, or harsh chemicals that can degrade cushion materials.

For best hygiene and function, replace cushions and foam inserts every 6 months with regular use.

Two cushions (sealing rings) and two foam inserts, plus installation instructions.

Replace when you see cracks, permanent compression, stiffness, or poor seal.

Replacement inserts and sealing rings are available as hygiene kits. If you use your hearing protector daily, we recommend that these parts be replaced at least twice a year.

Easy replacement as shown below.

Note: The illustration shows a Sordin Supreme model, however the principle is the same for all Sordin product families.

Replace the hygiene kit. Compressed foam reduces comfort and can affect sound quality in electronic models.

Store in a cool, dry place away from direct sunlight. Use the included bag if provided.

Remove batteries from electronic models, clean thoroughly, and store in a dry environment.

Avoid storage in extreme heat or cold. Bring to room temperature before use if stored in cold conditions.

Check battery direction (+/–), replace batteries, and hold the power button for 2 seconds.

Ensure power is on, volume is up, and battery compartment is properly closed.

Replace with fresh AA batteries — this usually indicates low power.

Make sure the microphones aren’t blocked and that volume is not at minimum.

Lower volume or switch to another audio profile (Focus/Dual).

Auto power-off activates after 4 hours of inactivity — press any button to stay active.

Check for moisture or loose batteries; dry and reseat.

Both are measures of how well a hearing protector reduces sound. In the US, NRR (Noise Reduction Rating) is used for ANSI certification. In Europe, SNR (Single Number Rating) is used for CE certification. There is no exact conversion rate, but SNR values are typically about 3–5 dB higher.

You find the serial number under the inserts.
