Cască Nitecore NE20

These tactical earbuds address noise hazards from environments such as shooting ranges and industrial workplaces by combining active and passive attenuation. They reduce the risk of hearing damage caused by prolonged exposure to loud sounds, while preserving the ability to hear speech and manage calls. The product integrates fast-reacting protection specifically designed for firearm discharge and offers Bluetooth 5.3 connectivity with a rechargeable USB-C case for extended use.

Advantages

Double hearing protection pairs ANC (Active Noise Cancellation) for low-frequency sounds with memory-foam passive sealing for high-frequency reduction. Fast Reaction Technology responds within 0.1 s at the moment of firing to attenuate impulse noise. Clear voice tracking maintains intelligible speech in noisy surroundings. Bluetooth 5.3 ensures lower power consumption and a stable wireless connection. Long battery life provides up to 8 hours per charge and a total runtime of up to 32 hours with the charging case. A single-button interface allows quick mode switching and call control.

How to use

Insert the memory foam ear tips into the ear canal and allow them to expand for a secure passive seal. Power on the earbuds and pair via Bluetooth 5.3 with your device; follow your device’s Bluetooth pairing prompts. Use the single-button control to switch modes, accept or end calls, and activate any ANC functions according to the device indicators. Place the earbuds back into the USB-C charging case when not in use to recharge; a full earbud charge takes about 1 hour.

Recommendations

For optimal protection in tactical shooting or high-noise workplaces, combine both active and passive features by ensuring a proper seal with memory foam tips and enabling ANC for low-frequency impulses. Regularly charge the case to maintain the full 32-hour available runtime and inspect ear tips for wear to preserve noise attenuation performance.
