REVUEPart 2 Headphones Published 02/02 Headphones Pictograms Frequency response The frequency response characterises the range of frequencies which a pair of headphones can reproduce. It is measured in hertz (Hz). The average human ear is capable of hearing frequencies ranging from about 20 Hz to 16,000 Hz. The frequency response alone does not reveal much about the reproduction quality. Total harmonic distortion (THD) The THD represents the percentage of non-linear distortions of a signal, the so-called harmonics. These particularly occur at lower frequencies when the motion of the diaphragm cannot follow the electrical signal precisely. Impedance Impedance is the headphones’ resistance to alternating current and is measured in ohms (Ω). The impedances of Sennheiser headphones range from 16 to 600 ohms which means they can be connected to all standard hi-fi components. Signal-to-noise ratio Difference between the wanted signal and the background noise of an electrically operated device (e.g. amplifier, microphone). Signal-to-noise ratio is measured in dB.

Dynamic headphones (Headphones, Dynamic) Sennheiser’s HD range of headphones are fitted with electrodynamic transducers. They are normally equipped with a 3.5 mm stereo jack plug and a 1/4” (6.3 mm) adaptor and can therefore be connected to all standard headphone outputs (amplifiers, CD players, DAT, DCC, MD, TV, personal stereos, camcorders etc.). Sennheiser’s range includes both open and closed headphones. Closed models provide better attenuation of surrounding noise, while open headphones give a more spacious sound. HDC... NoiseGard™ headphones (Headphones, Dynamic with noise Compensation) The HDC series of headphones are fitted with active noise compensation (NoiseGard™) circuits which considerably reduce external low frequency noise. HDC 451-1 NoiseGard™ mobile HE... Electrostatic headphones (Headphones, Electrostatic) Sennheiser’s HE headphones are fitted with electrostatic transducers. Their operation requires a polarising voltage, so a special amplifier is needed to process the audio signal. IS... Cordless infra-red systems (Infra-red System) The IS series consists of complete systems of infra-red transmitters and headphones. It incorporates both traditional analogue and modern digital technology. HDI... RI... Dynamic infra-red headphones (Headphones, Dynamic, Infra-red) Infra-red stethoset receivers (Receiver, Infra-red) As only one infra-red transmitter is necessary to operate as many infra-red headphones as desired, Sennheiser offers supplementary headphones. Classic headphones are designated by the letters HDI, stethoset receivers by the letters RI. RS .... Cordless radio frequency systems (Radio frequency System) The RS series consists of complete systems of RF transmitters and headphones with integrated RF receivers. HDR .... RR .... Dynamic radio frequency headphones (Headphones, Dynamic, RF) Radio frequency stethoset receivers (Receiver, RF) As RF transmitters can be used with any number of RF headphones, Sennheiser offers supplementary headphones. Classic headphones are designated by the letters HDR in their model number, RF stethoset receivers by the letters RR.

For this reason.. When an alternating current (i. The headphones’ diaphragm is attached to a coil of wire held in suspension in the field of a permanent magnet. This coil field interacts with that of the permanent magnet and causes the coil (and thus the diaphragm) to move forwards and backwards depending on the direction of current flow. Sennheiser use coils made from aluminium copper or even pure aluminium in their high-quality headphones.e. 5 Connection cables All dynamic headphones (with the exception of the HD 25 and HD 25 SP) are supplied with oxygen-free copper cables.e. This vibration of the diaphragm produces pressure sound waves. Description of models HD . Publ. HD headphones are equipped with dynamic transducers. the original audible audio information..

No. Publ.. HDI . Supplementary IR headphones are designated by the letters HDI in their model number. but over a narrow range of frequencies in the infra-red light spectrum. 02/02 . The optical power output of an infra-red diode is only about 16 mW (GaAs) or 20 mW (GaAlAs). depending on the type of diode used. carrier frequencies of up to 2. a current is generated in the diode. so Sennheiser uses a combination of amplitude and frequency modulation. RI . The transmitter diodes work in conjunction with the receiver’s photodiodes which convert the incoming infra-red light signal back into an electrical signal. low frequencies are subject to interference from fluorescent lights in this type of system.8 MHz can be used.. a television infra-red remote control. as the infra-red signal is restricted to the room. for example. Each channel of a stereo signal uses a carrier frequency that is amplitude-modulated... The light is not radiated at a single frequency. with the radiated pattern being controlled by the diode’s lens.. Modulated infra-red light replaces the cable linking the sound source to the headphones. Because of the very small photosensitive surface area of 7 mm2. and a corresponding infra-red receiving diode.. Infra-red audio transmission is the ideal solution where cordless headphones are required for different sound systems in the same building. Supplementary IR stethoset receivers are designated by the letters RI in their model number. The radiated light has a wavelength of approximately 880 nm or 950 nm. The simplest form of modulation operates by varying the intensity of the light in relation to the sound signal. Complete systems consisting of infra-red transmitters and headphones can be identified by the inclusion of the letters IS in their model number. However.. A “black filter” is also used with the receiver diode to filter out the effects of visible light.Headphones Cordless IR Headphones How infra-red technology works Cordless infra-red audio transmission overcomes the constrictions of a headphone cable. The transmitter emits the IR light from a row of light-emitting diodes (LEDs). so a number of emitter diodes are used to increase the overall radiating power of the transmitter. The infra-red diodes are modulated by varying the intensity of the light they emit. receiver diodes are usually used in conjunction with convex “frog eye” shaped lenses. This is also the operating principle of. 37 Description of models IS. the audio signal is then frequency-modulated onto this carrier. By the use of modern technology. When light is received by the photodiode... The basic infra-red transmission path consists of a transmitting diode which radiates the infra-red light. 2. consisting of infra-red transmitter and stereo stethoset receiver IS 300-120 IS 300-UK 40 IS 380 Headphone system. 04379 04380 04381 04150 04151 04152 04449 04450 04451 38 Overview 2. consisting of infra-red transmitter and mono stethoset receiver Page 39 IS 300 Stereo Stethoset system.Headphones Cordless IR Headphones Cat.

Please note: Due to varying licensing regulations. 43 Description of models RS . the sound transmitted is directly reproduced and the receiver is mobile. 2.g. Supplementary RF headphones are designated by the letters HDR in their model number... from amateur radio transmission. HDR . e. demodulates it and converts it back to the original audio signal. Of course. We would therefore advise purchasing a system only in the country of intended use. The RF headphones have a built-in receiver which picks up the radiated signal. thus ensuring optimum reception – systems which are operated close to one another can be set to different channels. so the headphones have a tuning control to set them to the channel chosen on the transmitter.. not all headphone systems are legal in all countries. A special filter protects the headphone receiver against interfering signals e.. 02/02 .. Here. The great advantage of RF transmission over infra-red transmission is that the RF audio signal can travel through walls and ceilings – which offers an unmatched freedom of movement. In the transmitter. the transmitter and the headphone receiver have to operate on the same frequency. the audio signal is modulated onto an RF carrier and then radiated via the transmitter’s antenna. the cable linking the sound source to the headphones is replaced by radio waves – just as infra-red light replaces the cable for infra-red headphones.Headphones Wireless RF Headphones How radio frequency technology works Sennheiser’s latest headphone development are wireless headphone systems with RF audio transmission. with headphones. Most Sennheiser RF systems feature three switchable channels. so the user can move around in the house or even outside. in the garden. The basic RF transmission path consists of a transmitter connected to the sound source which transmits the audio signal to an RF receiver integrated into the headphones. Publ. Complete systems consisting of RF transmitters and headphones can be identified by the inclusion of the letters RS in their model number....g. The technology used is basically that of the tried and tested RF transmission systems used on stage – only that.
