Comparison Sordin Supreme MIL AUX Neckband vs Sordin Supreme Pro X Neckband

An indicator of how much volume in decibels tactical headphones cut during operation. Acoustic efficiency NRR (Noise Reduction Rating) is the sound absorption characteristics according to the requirements of the American quality standard. A similar standard in the European style is called SRR (about it, see above).

NRR is an assessment of how effectively a hearing protection device can reduce ambient noise levels. If headphones are marked with the “NRR 30 dB” mark, then they can reduce the level of external sounds by 30 dB. The higher the NRR value, the more effective the tactical headphones are at protecting the hearing aid.

Operating time of the headphones on one set of replaceable batteries or a full charge of the built-in battery (see “Power source”).

Using this parameter, you can roughly estimate the duration of use of tactical headphones without the need to replace batteries or recharge the power source. It is also intended to compare the real capabilities of different models.
