Product type

Wearing style

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.

Headset type

The colour e.g. red, blue, green, black, white.

Product colour

The specific functions assigned to the physical buttons on the device, such as volume control, play/pause, or power.

Operating keys

The mechanism used to adjust the audio output level (e.g., Rotary, Button, or Touch).

Volume control

Specifies the design and placement of the interface used to manage device settings, such as an in-line control unit integrated into the cable.

Control unit type

The way in which the device is controlled.

Control type

The specific status lights available on the unit to provide visual feedback on its current state or connectivity (e.g., AC input, ACT, or Access).

LED indicators

The maximum number of previously connected devices that the unit can store in its memory for quicker future pairing.

Number of paired devices remembered

The maximum number of separate devices that can be linked to the unit at the same time.

Number of simultaneously connected devices (max)

Country where the device is made. Aka Country of manufacture (COM).

Country of origin

Performance

The technology that enables connectivity of the device, e.g. wired or wireless.

Connectivity technology

USB connectivity

What type of USB connector is built into the device.

USB connector

Bluetooth is a low-power radio technology developed to replace the cables and wires currently used to link or connect electronic devices such as personal computers, printers, and a wide variety of handheld devices including mobile phones. Because it uses radio-wave connectivity, a Bluetooth-enabled device has a constant, established connection to whatever browser it uses. This saves the user the trouble of logging on to check for emails or news updates, for example.

Bluetooth

The type of bluetooth technology in the product e.g. Bluetooth Smart (v4.0).

Bluetooth version

The maximum distance over which the device can maintain a stable wireless connection, typically measured in metres.

Wireless range

Ports & interfaces

The highest amount of electrical power that can be safely supplied to the device, measured in mW.

Maximum input power

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 measure of how efficiently the unit converts an electrical signal into sound, typically expressed in decibels per millivolt (dB/mW).

Headphone sensitivity

The diameter of the internal diaphragm responsible for producing sound, measured in millimetres.

Driver unit

Headphones

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.

Microphone type

The range of frequencies (low to high sounds) that the microphone can pick up (detect).

Microphone frequency

The minimum sound pressure level required to produce a specific electrical output signal, typically measured in decibels (dB).

Microphone sensitivity

The total quantity of integrated microphones built into the device.

Number of microphones

Indicates whether the product incorporates a miniature integrated microphone based on micro-electro-mechanical systems technology.

MEMS (Micro-Electro-Mechanical System) microphone

Indicates whether the integrated microphone can actively reduce background noise to improve voice clarity.

Microphone noise-canceling

Microphone

Indicates whether the product is powered by batteries.

Battery operated

Description of battery supplied with the product, such battery form factor (e.g. AA/AAA).

Battery type

Number of hours on average for continuous play. This is dependent on the device battery capacity.

Continuous audio playback time

The total time a battery can power a device for calls. As the device drains the battery during a call, the talktime left in the battery is diminished until the device is turned off or the battery recharged. The longer the talktime the less frequently you will need to recharge. Talktime, expressed in hours and minutes, is much shorter than standby time because transmission requires more power.

Talk time

Approximate time required to recharge the battery from completely empty to completely full
