Sennheiser CXC 700 3.5mm Connector Canal Earphone with NoiseGuard / Digital Noise Cancellation

With three user-selectable active noise cancellation modes and talk-through capability, these ear canal phones offer a high-tech solution for almost any listening environment. They look great, too.

Sennheiser takes their legendary acoustic technology to a new level with the CXC 700 inaugural travel headphones. It features a highly advanced acoustic system for excellent audio performance, suitable for listening to all types of audio content. In addition to the proven passive noise attenuation of 25dB (for frequency range above 3000Hz), the Sennheiser's newly developed active noise canceling technology - NoiseGuard / Digital Noise Cancellation - identifies and reduces even more unwanted ambient noise, perfect for discerning business travelers and frequent flyers, and includes three modes to match different acoustic environments for optimized noise reduction.

With the TalkThrough function, you can immediately mute the audio input and listen to your external environment or communicate with others. An intuitive control for NoiseGuard / Digital Noise Cancellation, TalkThrough and volume level has been conveniently placed for quick, one-handed adjustment. Best of all, a rugged yet elegant carrying case is included for easy storage for all your accessories, making them the perfect travel companion for sophisticated frequent flyers and travelers.

  • Superior Sound Equipped with a highly advanced acoustic system, the Sennheiser CXC 700 delivers spectacular audio performance to meet even the most difficult-to-please audiophiles.
  • NoiseGuard / Digital Noise Cancellation Technology Coupled with the already excellent passive noise attenuation of 25dB (for frequency range above 3000Hz), the NoiseGuard / Digital Noise Cancellation identifies and reduces even more unwanted ambient noise, offering an impressive active noise attenuation of up to 23dB, along with three modes that suit your various listening environments.
  • TalkThrough Function The TalkThrough function allows you to immediately mute the audio input and communicate with others, without the hassle of removing your earphones.
  • Convenient Control The integrated control box provides easy, single-handed control for NoiseGuard / Digital Noise Cancellation, TalkThrough and volume level even in low lighting condition.
  • Long Lasting Battery Benefiting from the high-efficiency circuit and refined technology, the active NoiseGuard / Digital Noise Cancellation provides up to 16 hours of battery life with a single alkaline battery.
