Sennheiser’s CXC 700 headphones have 3-levels of noise cancellation
The Sennheiser high-end [amazon_link id=”B004HD4L1U” target=”_blank” ]CXC 700[/amazon_link] ear-canal noise-cancelling headphones feature Sennheiser’s unique NoiseGard /digital system, which includes not one, but three noise-cancelling modes:
- Mode 1 is for use on low-frequency noise (100 to 400 Hertz), such as engine noise from trains, buses or small passenger planes.
- Mode 2 is for medium frequency range (400 to 3,000 Hertz), caused mostly by air-conditioning systems in large passenger aircraft or office buildings.
- Mode 3 has a wide frequency range (100 to 3,000 Hertz), and combines the noise-cancelling effect in the medium and low-frequency ranges. Because of this, background noise experienced in airports, railway stations or underground stations can be suppressed, but with slightly lower noise-cancelling performance than the first two modes.
The compact CXC 700 headphones have an ergonomic design and are operated using a control unit located on the 4.5-foot-long cable. This is where you can select one of the three NoiseGard profiles, control the volume, and also activate the Sennheiser TalkThrough function, which allows you to talk to someone without removing your earphones. In addition, changing between the NoiseGard profiles and the TalkThrough feature are indicated by both an acoustic and a visual signal.
The CXC 700 comes with a set of ear adapters in three different sizes, an in-flight adapter and a 6.35 mm jack plug adapter for connection to portable players and in-flight entertainment systems. In addition to a small carrying case, the set also includes a diaphragm protector, a cleaning tool and an AAA battery.
