Sennheiser introduced the CXC 700 noise-cancelling in-ear headphones with NoiseGard technology, which allows users to choose from three noise-cancelling modes optimized to reduce low, medium and high frequency noise.
- Mode 1 is effective on low-frequency noise in particular (100 to 400 Hertz), such as engine noise from trains, buses or small passenger planes.
- Mode 2 focuses on cancelling noise in the medium frequency range (400 to 3,000 Hertz), which is caused mostly by air-conditioning systems in large passenger aircraft or office buildings.
- Mode 3 has a particularly wide frequency range (100 to 3,000 Hertz), and combines the noise-cancelling effect in the medium and low-frequency ranges.
As a result, background noise with different noise components–such as that experienced in airports, railway stations or underground stations–can be effectively suppressed, although with slightly lower noise-cancelling performance than the first two modes.
To ensure that you can enjoy top-quality sound while traveling — even when the NoiseGard function is deactivated — Sennheiser's proven acoustics guarantees a balanced, detailed sound image with a frequency response of 20 to 21,000 Hertz. Whether noise cancelling is switched on or off, the CXC 700 promises the same perfect sound quality at all times. And when the battery life is diminished, the CXC 700 continues to operate as a traditional headphone for continuous listening enjoyment.
The CXC 700 is operated using a control unit integrated into the cable. The control unit is used not only to select the three NoiseGard profiles and to regulate the volume but also to activate the Sennheiser TalkThrough function. This allows users to conduct a conversation with the person sitting next to them or with the cabin staff without the need to remove their earphones. Activation of the NoiseGard profiles and TalkThrough function are indicated by both an acoustic and a visual signal.
The high-end ear-canal phones are also equipped with all the extras for relaxed and trouble-free traveling. The CXC 700 includes a set of ear adapters in three different sizes to guarantee a perfect fit and excellent noise suppression. An in-flight adapter and a 6.35 mm jack plug adapter are also included for connection to both portable players and in-flight entertainment systems. The 4.5-foot-long (1.4 meter) cable offers sufficient freedom of movement in all situations. In addition to a small carrying case, the set also includes a diaphragm protector, a cleaning tool and an AAA battery.
“NoiseGard /digital is the consistent further development of Sennheiser's analog NoiseGard technology,” explained Daniel Chee, Product Manager for the Sennheiser Travel Line. “The possibility to select one of three different modes that are optimized for different environments considerably improves the noise-cancelling effect. Precise filters generate a result that is up to five times better than that of the analog system.”
