The middle of the range
SNR 31 dB, H 33, M 29 and L 21 dB. With the M value and a 5 dB real-world deduction, the EP901 covers workplaces of about 94 to 104 dB(A) for mid- to high-frequency noise, which suits most noisy production areas.
Unopened, the hearing protector keeps for five years from manufacture according to the user instructions. Cushions and foam pads are cleaned after use with mild soap or alcohol wipes.
Correct use in four steps
- 01
Open the cups
Pull the cups outwards and place them over the ears.
- 02
Enclose the ears
The cushions must completely enclose the ears and sit tightly against the head. Hair, caps or spectacle arms disturb the seal.
- 03
Adjust the height
Adjust the height of both cups until the fit is firm and comfortable. The headband sits straight on the head.
- 04
Clean
After use, clean cushions and foam pads with mild soap and water or alcohol wipes and leave them to air-dry.
