Noise-canceling circuit senses outside noise with built-in microphones and sends an equal-but-opposite canceling signal to the headphones. Passive feature allows the headphone to function as regular stereo headphones without using the noise-canceling feature or required battery. In-the-ear design allows earbuds to fit comfortably inside the ear. Design includes a small battery box for included AAA battery. Earbuds offer 1.5m cord, L-shaped stereo mini plug, neodymium magnet for powerful sound, 13.5mm dome-type driver, more than 12dB at 300HZ frequency range, 8 to 22,000Hz frequency response, 20 ohms at 1kHz impedance (power on), 8.5 ohms at 1kHz impedance (power off), 102dB/mW sensitivity (power on), and 100dB/mW sensitivity (power off). Earbuds include an in-flight adapter, ear pad, three set of earbud cushions (small, medium and large) and carrying pouch. Minimize |
