Engineered for discerning business travellers and frequent flyers, Sennheiser CXC 700 earphones feature the latest incarnation of SennheiserÃ¢â‚¬â„¢s active noise cancelling technology - NoiseGard / digital, which identifies and reduces 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.
With NoiseGard / digital, the CXC 700 offer an impressive active noise reduction of up to 23dB and this adds to their already excellent passive noise attenuation of 25 dB (for frequency range above 3000 Hz). The CXC 700 are also equipped with TalkThrough function, which mutes the audio input and allows you to listen to your external environment, enabling you to communicate with the flight attendant or your fellow travel mate without removing the ear canal phones.
Their sleek and ergonomic control box houses a single AAA alkaline battery that lasts for up to 16 hours of continuous usage. The intuitive controls for NoiseGard / digital, TalkThrough and volume level have been conveniently located so as to allow for quick and easy single-handed adjustments, even in low light conditions.
