Headphones
Ear coupling Ear coupling describes the way in which headphones or earphones stay attached to, or inside, the ear. There are three common types of ear coupling: circumaural, supra-aural and intra-aural. Circumaural headphones enclose your ears with large pads that suppress external noise. Supra-aural headphones are typically more lightweight and sit on top of the ears with small pads. Intra-aural headphones come in two basic designs and neither style sits on the head itself. The first are ear buds, which sit just outside of the ear canal, on top of your ear lobes. The second type is actually inserted directly into the ear canal and offers some external noise suppression.	Supraaural
Acoustic system	Closed
Headphone frequency The range of frequencies (low to high sounds) that the headphones can produce.	20 - 20000 Hz
Impedance The effective resistance of an electric circuit or component to alternating current, arising from the combined effects of ohmic resistance and reactance.	32 Ω
Headphone sensitivity	102 dB
Driver unit	3,2 cm
Driver type	Dynamic
Noise canceling
Noise canceling type	Hybrid
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%.	3%

Microphone
Microphone type The characteristics of the microphone bulit into the device in terms of the reception of signals from all or just one direction, i.e. omnidirectional (better for concerts and the like vs unidirectional, more suitable for voice recording.	Boom
