  • Noise canceling technology
    Noise canceling headphones reduce ambient noise and provide a quieter environment to enhance audio entertainment. The headphones have an inside microphone on each earpiece that work with an electronic circuitry to create an opposite sound wave to reduce wave. Ambient sound is reduced by synthesizing with a sound in opposite phase produced by the noise canceling circuit.
  • Noise reduction
    Reduces up to 99 percent ambient noise (20 dB at 160 Hz) when noise canceling circuit is switched on.
  • Ideal for:
    Loud, noisy environments ? planes, trains, buses, work or dorms.
  • Digital Equalizer
