Noise Canceling Earphones TNC350

By using microphones & electronic circuitry (built inside earcups), which generationg an "Antinoise" sound wave, efficiently invert the captured external signal upside down, this results a destructive interference and cancels out the noise.
Medium size, closed back earcups design, help blocking sounds when in a noise environment, to hear a more clear sound.
