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%.

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.
