The 3M H510B Peltor Optime I Ear Defenders are lightweight hearing protection for moderate industrial noise, such as in workshops, sheet-metal shops and printing works. They also suit outdoor use, for example when mowing the lawn, and hobby and leisure activities.
They work well for both short and long spells of wear. The low-profile cups pair easily with other equipment, and the fluid and foam filled sealing rings give a good seal with low contact pressure.

Understanding the attenuation values
The SNR of 26dB is a single overall figure for the noise reduction. The H, M and L values show the reduction across high, medium and low frequency noise: H=30dB, M=24dB and L=15dB. Use these to check the protection suits the type of noise in your work area.
