E-A-Rflex Foam Tips Semi-Insert Hearing Protectors, E-A-Rflex Banded Ear Plugs - 10 Pairs/Box - 100 Pairs/Case

Commonly worn behind the head or under the chin banded ear protectors are a comfortable, effective, lightweight alternative to earmuffs.
The plastic band helps prevent loss and is ideal for intermittent use.
The flexible frame also makes them ideal for uses where frequent removal and re-fitting is required for conversations, etc.

• Banded hearing protector - wearable in 3 positions
• NRR 25dB - highest NRR for a semi-insert in all three positions
• Dermatologically safe polyurethane foam has been tested and rated non-irritating to the skin, but does contain a trace amount of latex
• Jointed frame allows greater adjustability for fitting to your head than a plain band
• Note that the NRR may overestimate the hearing protection provided during typical use

3M recommends reducing the advertised NRR by 50% for estimating the actual amount of noise reduction provided
