Headphones
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%.

International Protection (IP) code:The IP code classifies and rates the degree of protection provided against the intrusion (including body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures. It is published by the International Electrotechnical Commission (IEC). The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. Where there is no protection rating with regard to one of the criteria, the digit is replaced with the letter X. an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. Another example is the Sony Xperia Z Ultra, one of the first cellular phones to be IP-rated; it is rated at IP58 and marketed as "dust resistant" and can be "immersed in 1.5 meter of freshwater for up to 30 minutes".
