About This Product
■What are digital earplugs?
This device can only cancel out environmental noise, allowing you to clearly hear calls, announcements, and ringtones even at manufacturing sites. A small microphone built into the earphones picks up surrounding environmental noise and produces sound with the opposite phase to cancel out the noise.
■Features
・Collects surrounding environmental noise with a small microphone built into the earphones
・The noise canceling circuit of the main unit generates opposite phase (inverted) sound.
・By combining two waveforms, noise is canceled in the ear.
■Choice of attachment method
It can be attached to clothes using a clip, so it won't get in the way of your work.
■3 types of mode switching
You can switch between the following three modes using the mode change button on the controller.
・Noise canceling mode "Strong"
・Noise canceling mode "weak"
・External sound engagement mode
