Total Harmonic Distortion (THD):Total harmonic distortion is a measure of non-linear harmonic\n\ndistortion and is given in %. Non-linear harmonic distortions are\n\nsignals which were not present in the original before the signal was\n\nconverted by the headphones. These unwanted signals are caused by the\n\ndiaphragm, whose movements do not precisely move in time with the\n\nelectric signals that cause it to move. Unfortunately, this is a\n\nfeature of all electroacoustic transducers. Although it cannot be\n\ncompletely eliminated, suitable steps can be taken to minimise it.\n\nHowever, the user is not interested in why this distortion takes place\n\nbut in how great the level of distortion must be for it to become\n\nperceptible. According to the findings of several research projects, a\n\ntotal harmonic distortion of 1% in the frequency range of 100 to 2000\n\nHz is imperceptible. Below 100 Hz, the perceptibility threshold lies\n\nat 10%.

Magnet type:Type of magnet e.g. neodymium.
Neodymium
Headphone sensitivity:
93 dB
Impedance:The effective resistance of an electric circuit or component to alternating current, arising from the combined effects of ohmic resistance and reactance.
32 O
Headphone frequency:The range of frequencies (low to high sounds) that the headphones can produce.
20 - 20000 Hz
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.

Plug and Play:Indicates whether this product supports is "plug and play". Plug and play is hardware or software that, after being installed ("plugged in"), can immediately be used ("played with"), as opposed to hardware or software which requires configuration.
Cable length:How long the cable is.
1.5 m
Foldable:The product can be folded and so can be stored/transported more easily.
Control type:The way in which the device is controlled.
Buttons, Lever, Rotary
Control unit type:
In-line control unit
Operating keys:
Play/Pause, Track <, Track >
Headset type:A headset is headphones combined with a microphone, or one headphone with a microphone. Headsets provide the equivalent functionality of a telephone handset but with hands-free operation. Types of headsets include single earpiece (monaural) and double earpiece.
Binaural
Recommended usage:What the product should be used for, and how it should be used (e.g. ambient temperature).
Music
Wearing style:The way in which the device is worn.
Head-band
Product type:The sub-category of the product.
Headset
Ports & interfaces
Connectivity technology:
Wired
