Despite its thin profile, the Razor series is rated for a Noise Reduction Rating (NRR) of 23 dB. That equates to about a 400% sound reduction at the ear. The Razor Patriot is powered by two “AA” batteries to operate the Omni-directional microphones and HD speakers featuring a .02-second reaction time. Like all headphones, a proper fit is necessary, but not all headphones are the same. Read the full review to learn how the Razor performed at the range.
