WARNING TO USER

01. BattlePlugs reusable earplugs must be fitted and worn correctly to provide effective protection. Wash or clean hands 

 before use. Plugs should be routinely washed with mild soap and warm water. CAUTION: Remove with a slow twisting

 motion to break the seal. Due to the tight seal, rapid removal may damage eardrum.

02. Use this laboratory-derived attenuation data for comparison purposes only. The amount of protection afforded in field 

 use often is significantly lower depending on how the protectors are fitted and worn.

03. Failure to follow all instructions could result in hearing loss or injury. Failure to obtain a proper fit will reduce 

 effectiveness of hearing protectors and could result in hearing loss or injury.

04. BattlePlugs must only be used as part of a hearing conservation program that complies with applicable local safety 

 and health regulations.

05. Overprotection can be dangerous. The wearer must be able to hear warning signals.

06. Wearers with hearing loss should exercise extreme caution.

07. It is the employer’s responsibility to ensure that the type of hearing protector and its NRR is appropriate for the user in

 their particular workplace.

08. Use caution when working around machinery or other equipment to ensure neck cord does not become caught or 

 entangled.

09. Failure to follow these warnings could result in serious injury or death.

10. Although hearing protectors can be recommended for protection against the harmful effects of impulse noise, the 

 Noise Reduction Rating (NRR) is based on the attenuation of continuous noise and may not be an accurate indicator 

 of the protection attainable against impulse noise such as gunfire. (Wording required by EPA)

CLEANING & INSPECTION

Wash with soap and water only, and dry thoroughly before re-wearing. Keep filter hole in tip and handle free of earwax, 

dirt and dust. Confirm filter holes are clear by holding plug up to light source. If you cannot see light shining through filter 

holes rewash and check again. If unable to clear filter holes, replace earplugs. Inspect plugs for any tears or damage 

each time they are worn and replace immediately if necessary.

Fitting/Usage Instructions

Important Information

When cap is open, this earplug can be used to reduce impulse noises, such as gunfire, 

while also allowing you to hear low level noise. In closed cap position it can be used to 

help protect against continuous and impulse noises. Training is required. Before first 

use, practice opening and closing cap while plug is NOT in the ear canal.

Cautions 

Improper fit and failure to wear at all times during exposure to loud noise, will reduce 

protection and result in hearing loss. Impulse noise will be louder with cap open than 

closed. Do not use with cap open during continuous high hazardous noise. Remove 

slowly by twisting to avoid damage to eardrum.

For use against continuous noise always wear with cap 

closed (Fig. 1)

A. Before inserting plug check to see that cap is fully closed shut (Fig 1).

B. Reach over the head and pull top of ear upwards (Fig 2).

C. With other hand grasp plug handle and gently push and wiggle into ear canal 

 until a good and comfortable seal is made.

For use against impulse noise when hearing other sounds/

communication is also needed, wear with cap open (Fig. 3)

D. If plug is already being worn with cap closed, you do not need to take plug out 

 to open cap (Fig 4).

E. To open cap, depending on the orientation of the handle, use either your thumb 

 or index finger to gently push out on the cap latch while resting the other on the 

 hinge, (this may take practice) (Fig 5).

F. To insert plug with cap open, reach over the head and pull top of ear upwards 

(Fig 6).

G. With other hand grasp plug handle and gently push and wiggle into the ear canal 

 until plug is resealed and comfortable.

Closing cap with plug in ear.

H. To close cap you do not need to take plug out.

I. Depending on the orientation of the handle, use either your thumb or index 

 finger to gently push the cap into the handle until it is fully shut, (this may 

 take practice) (Fig 7).

Ensure that cord does not interfere with the 

hinged cap fully closing. Failure to close 

the hinged cap completely may result 

in reduced noise attenuation. 

MOLDEX® BattlePlugs Impulse Earplugs

1 2 3 4 5 6 7

Patented Moldex BattlePlugs earplugs use a unique filter built into 

the plug body to instantaneously reduce dangerous, sudden 

impulse noises (e.g. weapons fire) plus allow for easy 

communication and improved awareness 

in the cap open position – NRR 9dB.

• Now an authorized hearing protector for use by soldiers and 

 Department of the Army civilians.

• Dual Mode Protection.

 – Open cap to hear commands and for loud blasts.

 – Closed cap for continuous/steady noise and impulse 

 noise protection.

• The louder the blast, the more noise 

 reduction (in open position).

• Cap is easy to open and close, in-ear.

• Easy to see when cap is in open 

 or closed mode.

• Easy to clean.

Single-Ended VersionIf the rocker cover is in Open/Weapons Fire mode, sound travels into the earplug and down the sound channel to the special fi lter. The fi lter allows lower-level sounds to pass with limited interruption but high-level impulsive noises are restricted. The more intense the impulse, the more it is limited.

Dual-Ended VersionSound travels into the opening at the middle of the earplug and down the sound channel in the yellow end of the earplug to the special fi lter. The fi lter allows lower-level sounds to pass with limited interruption but high-level impulsive noises are restricted. The more intense the impulse, the more it is limited.
