Engineered for discerning business travelers and frequent flyers, these premium ear canal phones feature the latest incarnation of Sennheiser active noise cancelling technology - NoiseGard / Digital - which identifies and reduces even more unwanted ambient noise. Moreover, its tri-mode design allows you to select from one of three different digital noise cancellation modes based on different acoustic environments: Mode 1 - Optimized for commutes on trains, subways, buses, cars and short distance flights; Mode 2 - Optimized for use on long-haul flights and in air-conditioned rooms; Mode 3 - Optimized for on-the-go use, in crowded environments or other loud surroundings. --With NoiseGard / digital, the CXC 700 offer an impressive active noise attenuation of up to 23dB and this adds to their already excellent passive noise attenuation of 25 dB (for frequency range above 3000 Hz).
