N301 is a intelligent noise-canceling walkie talkie.
We’ve heard a particular comment from our customers who work in warehouse or factory environments, their work environments are filled with loud machinery, fans, forklifts, and wind noise. Noise interfere with communications to the point that communications were next to impossible.
N301 solves these problems.
