General Description
Featuring the worldwide debut of NoiseGard(TM) Digital, the CXC 700 is the perfect solution for the never-at-home music fanatic.
If you demand more from your audio AND your airline the CXC 700 is up the to the task. Utilizing NoiseGard(TM) Digital, the user can select one of three modes of noise cancellation optimized for their current environment: ground transportation, long flights and crowded public places. Selecting the appropriate mode will reduce ambient noise- allowing the listener to hear subtle nuances in their music, relax and arrive less fatigued (while eliminating noise competition that could damage hearing).
The ear-canal design blocks ambient noise like an earplug, while the Sennheiser transducer pumps out rich, detailed sound quality with vibrant bass. Then, turn on NoiseGard(TM) for even more reduction of ambient noise; a sonic triple-threat.
A travel kit including case and audio adapters is included, and with all Sennheiser ear-canal headphones, a deluxe fit kit is included to maximize bass performance, comfort and noise isolation.
Mode 1 effective for low-frequency noise in particular (100-400 Hz), such as engine noise from trains, buses or smaller passenger planes.
Mode 2 focuses on cancelling noise in the medium frequency range (400-3,000 Hz), which is caused by most air-conditioning systems in large passenger aircraft and office buildings.
Mode 3 has a wide frequency coverage (100-3,000 Hz)

Glossary
| Cable length |
| The cable length is usually measured between the anti-kink sleeves of the cable (cable length without connectors). |
| Connector |
| A standardised single or multi-pole plug for connecting units or accessories. |
| Frequency response |
| The frequency response of a microphone is given within the limits defined by the manufacturer. In studio condenser microphones it is generally within the range of between 20 Hz and 20 kHz. |
| Impedance |
| Impedance expresses the AC resistance of a microphone or a set of headphones. It is dependent on frequency and is given at 1 kHz as the so-called nominal impedance. Impedance is measured in ohms. In recent years, an industrial standard has developed, setting the impedance of headphones at 50 or 600 ohms. Sennheiser headphones are manufactured according to this standard, thus practically ruling out connection problems. With microphones, the input impedance of the following microphone amplifier should have at least three times the value of the nominal impedance, in order to prevent it from unnecessarily attenuating the microphone signal. |
| Sound pressure level (SPL) |
| Due to the impractical numerical values, the sound pressure is usually given as the logarithmic value of the sound pressure level according to the equation: dB SPL = 20 x log (po / 0.00002 Pa). The abbreviation SPL (sound pressure level) is added in order to make a clear distinction from other uses of dB. The reference sound pressure, which is at the same time the threshold of hearing, is then 0 dB SPL. The threshold of pain is 140 dB SPL. A difference in the sound pressure level of 1 dB is just about perceptible, while a doubling of the sound pressure corresponds to 6 dB and a doubling of the volume corresponds to a rise of 10 dB. |
| Total harmonic distortion (THD) |
| Total harmonic distortion is a measure of non-linear harmonic distortion and is given in %. Non-linear harmonic distortions are signals which were not present in the original before the signal was converted by the headphones. These unwanted signals are caused by the diaphragm, whose movements do not precisely move in time with the electric signals that cause it to move. Unfortunately, this is a feature of all electroacoustic transducers. Although it cannot be completely eliminated, suitable steps can be taken to minimise it. However, the user is not interested in why this distortion takes place but in how great the level of distortion must be for it to become perceptible. According to the findings of several research projects, a total harmonic distortion of 1% in the frequency range of 100 to 2000 Hz is imperceptible. Below 100 Hz, the perceptibility threshold lies at 10%. |
| Transducer principle |
| Two transducer principles have become established for the conversion of electric energy into mechanical energy: electrodynamic and electrostatic transducers, whereby the latter is only to be found in audiophile systems, due to their relatively high manufacturing costs. Electrodynamic transducers basically consist of a ring-shaped permanent magnet and an oscillation coil, which is fixed to the receiver diaphragm. When an audio-frequency alternating current is passed through the oscillation coil, it is caused to vibrate in accordance with the audio-frequency alternating current, thus causing the diaphragm to vibrate in the same way. |
