The most common cause is a battery problem. Check the following:

1. Make sure both batteries are properly in place.
2. Make sure the battery cap is tightly sealed.
3. Make sure the batteries are sufficiently charged.
4. Still won't start? Contact us or check out our warranty page.

We don't sell our products directly to end customers, here you'll find contact information to our distributors!

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.

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.
