Key certifications:

NRR 21

An NRR of 21 means that the hearing protection is estimated to reduce noise levels by an average of 21 decibels across various frequencies.

'NRR' in hearing protection stands for 'Noise Reduction Rating,' which is a single value used to indicate the average level of noise reduction a hearing protection device provides across different frequencies, essentially telling you how much sound attenuation the earplugs or earmuffs will offer when worn correctly; the higher the NRR value, the greater the noise reduction level is considered to be.

NRR is primarily used as a rating system in North America, while Europe often uses 'SNR' (Single Number Rating) and Australia/New Zealand use 'SLC80'; which both differ slightly in calculation.

    Great value. It is so important that I can hear people speaking during work while also blocking out the factory noises.

    Really good value for money

    Bit pricey for the quality but work well, room for improvement.

    They are OK and do as required on the shot stop side of things, Look pretty cool and are comfortable to ware for hours shooting.

    Things to note they are obviously made in China with old style parts and cheap tech. The headphones port is probably the most obvious sign of this.

    Music volume when on Bluetooth is sub par.

    The cover for the batteries could be improved greatly. I imagine after a few on offs it will not want to stay in place, it offers no water protection if it were to rain, this I is it's weakest point.
