Sennheiser is expanding its Travel Line with the addition of a set of ear-canal phones with active noise cancellation, the CXC 700. What sets these earphones apart from the rest is the new NoiseGard/digital system which offers travellers a choice of three noise-cancelling profiles – optimised for a range of surrounding noise encountered while travelling.
One of three noise-cancelling profiles can be selected to adapt NoiseGard to the current surroundings. Mode 1 absorbs low-frequency noise in particular (100 to 400 Hz), 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 Hz), which is caused above all by air-conditioning systems in large passenger aircraft or office buildings. Mode 3 has a particularly wide frequency range (100 to 3,000 Hz), 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 which occurs at airports, railway stations or underground stations, can be effectively suppressed, although with a slightly lower noise-cancelling performance than in the first two modes.
Another unique aspect that the CXC 700 offers is the Sennheiser TalkThrough function, which 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. 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. the set also includes a small carrying case, a diaphragm protector, a cleaning tool and an AAA battery.
