Frequently Asked Questions - AESEM1S Klein Tools

How to clean Klein Tools AESEM1S earplugs?

Clean the earplugs with a damp cloth and mild soap. Avoid solvents or alcohol that could damage the foam. Rinse with clean water and air dry before storing.

What is the lifespan of the AESEM1S earplugs?

The earplugs are reusable and should be replaced approximately every 3 months, or sooner if they show signs of wear or deformation.

Are they reusable?

Yes, Klein Tools AESEM1S earplugs are reusable. They can be cleaned and reused until they lose effectiveness or shape.

How to properly insert the earplugs?

Roll the earplug between your fingers to compress it, then insert it into the ear canal. Hold it in place for 20-30 seconds while it expands. Proper insertion ensures optimal noise reduction.

What noise reduction do they offer?

The AESEM1S earplugs offer a Noise Reduction Rating (NRR) of 32 dB, making them suitable for noisy environments like construction sites or factories.

Are they suitable for people with narrow ear canals?

The memory foam conforms to most ear canal shapes. For very narrow canals, smaller earplugs are available. Check comfort and fit.

Can I use the AESEM1S earplugs for swimming?

No, these earplugs are designed for hearing protection against noise, not for water seal. For swimming, use earplugs specifically designed for water.

How to store the earplugs?

Store them in the provided carrying case, in a dry, clean place away from dust and moisture. Do not expose to extreme temperatures.

Are they compatible with a hard hat?

Yes, AESEM1S earplugs are compact and can be worn under a hard hat without discomfort. They provide additional protection in noisy environments.

Where to find replacement parts for the AESEM1S earplugs?

The earplugs are sold as a pair. For replacements, contact an authorized Klein Tools dealer or purchase a new pair. The carrying case can be replaced separately.

WARNINGS

Read, understand, and follow these instructions to ensure safe operation. Keep these instructions for future reference.

These hearing protectors help reduce exposure to hazardous noise and other loud sounds. Misuse or failure to wear hearing protection at all times that you are exposed to noise may result in hearing loss or injury.

• Inspect earmuffs before each use; damage to the earmuffs can reduce noise reduction performance.
• Improper fit of this device will reduce its effectiveness in attenuating noise. Consult the FITTING EARMUFFS section for best protection.
• Do not bend or reshape the headband as this will cause a reduced clamping force reducing the specified NRR (Noise Reduction Rating).
• Prolonged exposure to high volumes can cause hearing damage. It is the responsibility of the user to set the audio input level to the recommended volume. See table in FEATURE DETAILS section for noise exposure levels.
• DO NOT use this product in situations that require special attention: using noise reduction equipment and listening to audio can reduce awareness of the surrounding environment.

Failure to observe these warnings can result in risk of fire or electric shock.

• DO NOT use the product if it is damaged or modified. Damaged or modified batteries may exhibit unpredictable behavior resulting in fire, explosion, or injury.
• Risk of fire and burns. DO NOT open, crush, heat above specified maximum temperature or incinerate. Prolonged exposure to direct sunlight can result in elevated temperatures
  • DO NOT immerse in water or other liquids
• Properly seal the charging port cover to achieve specified water & foreign object ingress protection. Keep seal free of dirt, oil, sand, or other material that interferes with proper sealing. Failure to do so can result in risk of fire or electric shock.
• DO NOT open the charging port cover if wet or in a wet environment. Thoroughly dry the unit and the seal around water-resistant cover completely before opening water resistant cover.
• DO NOT subject to impacts or drops greater than 6.6ft. (2m). Drops larger than this may not show signs of damage, but internal components may have been compromised. It is advisable to replace the unit if any such severe events occur
• DO NOT attempt to repair the product or charging cable. There are no user-serviceable parts.

NOISE REDUCTION RATING (NRR)

The NRR for the AESEM1S SMART SENSE Situational Awareness Bluetooth® Earmuffs is 23dB. It is tested and in accordance with ANSI S3.19-1974. To ensure adequate hearing protection, the earmuffs must be properly fitted according to the FITTING EARMUFFS section.

ANSI S3.19-1974 TESTING

Frequency (Hz) 125 250 500 1000 2000 3150 4000 6300 8000 NRR
Mean Attenuation	18.9	19.4	25.5	33.7	36.0	40.1	44	41.	4	39.9
Standard Deviation	3.4	2.9	2.7	2.5	2.8	3.1	3.3	3	2.8

NOTE: The above table is based on a headband force of 12N.

The level of noise entering a person's ear when the hearing protector is worn as directed, is closely approximated by the difference between the A-Weighted environmental noise level and the Noise Reduction Rating (NRR).

EXAMPLE:

• The environmental noise level as measured at the ear is 89dB(A).
• The NRR is 23dB.
• The level of noise entering the ear is approximately equal to 66dB(A).

⚠️CAUTION: For noisy environments dominated by frequencies below 500 Hz, the C-weighted environmental noise level should be used.

NOTE: Although hearing protectors can be recommended for protection against the harmful effects of impulsive 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 impulsive noise such as gunfire. The Environmental Protection Agency uses the Noise Reduction Rating (NRR) as a rating of a hearing protector's noise-reducing performance. Klein Tools cannot guarantee the suitability of the NRR as a method of rating protection as protection relies on the level and exposure of sound and how well a product fits.

AUDIO INPUT LEVEL

The audio level in the hearing protector is dependent on the audio input level. To prevent harmful noise levels, the AESEM1S SMART SENSE Situational Awareness Bluetooth® Earmuffs automatically default to 85dB when wirelessly connected to a music device. If the hearing protector is connected to a music device with a high audio output level, it is the user's responsibility to set the audio input level to safe level. See table in FEATURE DETAILS section for noise exposure levels.

OPERATING INSTRUCTIONS

CHARGING EARMUFFS

1. Open the Silicone Port Cover ⑥ to access the USB-C Charging Port ⑦.
2. Using the included USB-A to USB-C charging cable ⑨, plug the USB-C end into the USB-C Charging Port ⑦ of the earmuffs while plugging the USB-A end into an appropriate charging source, such as a third party certified USB to AC wall adapter (not included, see GENERAL SPECIFICATIONS for charging requirements).
3. While the earmuffs are charging (0-99%), the Indicator LED ⑧ will breathe (dim to bright) red, and will illuminate solid green when fully (100%) charged.

FITTING EARMUFFS

1. Fold out the earcups from the storage position by extending the slider arms (FIG. 1).

2. Place earmuffs on the head positioning the earcups over each ear (FIG. 2). The inner headband is labeled (R or L) for convenience.

3. When placing the earcups over the ears be sure to:

4. Completely cover the ear, the ears should never be exposed (FIG. 3).

5. Avoid obstructions (such as hair) that would prevent a firm seal (FIG. 4).
6. Adjust the slider arms up or down to tighten or loosen the headband until a hugging seal and comfortable fit is achieved (FIG. 5).
