What the product should be used for, and how it should be used (e.g. ambient temperature).

Recommended usage

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.

Ports & interfaces

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.

Ear coupling

The range of frequencies (low to high sounds) that the headphones can produce.

Headphone frequency

The effective resistance of an electric circuit or component to alternating current, arising from the combined effects of ohmic resistance and reactance.

Impedance

Headphone sensitivity

Magnet type

Driver unit

The quantity of drivers, which are individual transducers that converts electrical energy to sound waves.

Number of drivers

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%.

Total Harmonic Distortion (THD)

Headphones
