4.1 Initial Charging

Before first use, fully charge both the earplugs and the charging case.

1. Connect the USB charging cable to the charging port on the case and to a power source (e.g., computer USB port, wall adapter).
2. Place the earplugs into their respective charging slots in the case. Ensure they are correctly seated.
3. The LED indicators on the case and earplugs will show charging progress. Refer to the LED indicator section for details.
4. Charging is complete when all indicators show a full charge. The charging case can provide up to 3 full charges for the earplugs, and the case itself offers up to 6.5 hours of power on a full charge.

4.2 Fitting the Earplugs

Proper fit is crucial for effective noise reduction and comfort. The M20T comes with various sizes of silicone and foam ear tips.

1. Select the ear tip size (S, M, L) that provides a snug and comfortable seal in your ear canal. Experiment with both silicone and foam tips to find the best fit.
2. Gently insert the earplug into your ear canal, twisting slightly until it feels secure and comfortable.
3. Test the seal by speaking or listening to ambient sounds. If sounds are not adequately attenuated or if the earplug feels loose, try a different size or type of ear tip.

4.3 Attaching the Anti-loss Lanyard

For added security, especially during active use, attach the anti-loss lanyard to the designated attachment points on the earplugs or charging case as desired.

5. Operation

5.1 Power On/Off

• Power On: Press and hold the power button on each earplug for approximately 3 seconds until the LED indicator illuminates and you hear an audible prompt.
• Power Off: Press and hold the power button on each earplug for approximately 3 seconds until the LED indicator turns off and you hear an audible prompt. Alternatively, placing the earplugs back into the charging case will automatically power them off.

5.2 Noise Reduction and Amplification

The Earmor M20T features active noise reduction with an NRR of 26 dB, effectively suppressing harmful impulse noises above 82 dB, such as gunshots. It also amplifies quiet sounds to improve situational awareness.

5.3 Switching Noise Modes

The M20T offers three distinct noise modes to adapt to different environments:

• Indoor Mode: Optimized for indoor shooting ranges or environments with reflective surfaces.
• Outdoor Mode: Best for open-air environments, such as outdoor ranges or hunting.
• Silent Mode: Provides maximum passive noise attenuation without sound amplification.

To switch between modes, short press the power button on either earplug (approximately 1 second). The earplugs will provide an audible prompt indicating the current mode.

5.4 Bluetooth Connectivity (BT 5.3)

The M20T earplugs feature Bluetooth 5.3 for wireless audio streaming and call management.

1. Pairing: When the earplugs are powered on for the first time or are not connected to a device, they will automatically enter pairing mode. The LED indicator will flash.
2. On your device (smartphone, tablet, etc.), enable Bluetooth and search for "Earmor M20T" in the list of available devices.
3. Select "Earmor M20T" to connect. Once connected, the LED indicator will stop flashing, and you will hear an audible confirmation.
4. Music Playback: Once paired, you can stream audio from your device. Use your device's controls for volume, play/pause, and track skipping.
5. Call Management: When a call comes in, the earplugs will ring. Press the power button once to answer/end a call.
