These stereo headphones feature active noise cancellation and deliver high quality audio from 20 Hz to 18 kHz with less than 1% THD. They can accentuate ambient noises (400 Hz to 1 kHz) up to approximately 10 dB. Internally mounted microphones receive noise locally at the headset. Active electronics invert this noise and sums it with the incoming audio signal. The result is reduced low frequency noises typically associated with engines, wind, and other sources. Headphone requires a 3.5 mm (1/8") jack for stereo audio and a 2.5 mm jack for +12 VDC power. These headphones are small, lightweight and comfortable to wear. Ear pads are easily changeable.
PLEASE NOTE: A special connector is provided for audio and power connections. The 3.5 mm connector is a standard stereo plug with left, right and common connections. The 2.5 mm connector is a three (3) section plug with the center band serving as an isolator between +12 VDC and ground. This prevents "sparking" when plugging in the headphone. Cord exits assembly opposite the 2.5 mm plug. Overall Rating for Sennheiser HDC45-16 NoiseGuard Mobile Headphones
