IMPEDANCEOhmExpresses the resistance of the headphones to the alternating electric current that passes through it. Its value changes according to the frequency.
SIZE OF THE DRIVERSmmOn a headset, each earphone embeds a kind of small speaker, called “Driver”. On the driver of a gaming headset, the membrane is generally round and is measured in millimeters on its diameter.
SENSITIVITYdBSensitivity is the maximum sound level (or SPL, Sound Pressure Level) that a headset can deliver from a given power.
FREQUENCY OF ANSWERHetzThe majority of headphones are supplied between 20 Hz and 20 kHz, since this is the audible frequency range for the human ear.
7.1 DIGITAL SURROUND SOUND SYSTEM Sound virtualisation technology that directly adapts Dolby Pro Logic IIz signals (7.1 surround sound). It is starting to appear on some headsets that accept a USB sound input. In some games, where this spatialization allows the position of enemies infiltrating from the rear to be identified by ear. From now on, 3D does not only apply to the image and the representation of the game universe, it also applies to sound.

SWITCHThe technology of the switch hiding behind the keys and buttons of the mouse or keyboards. For example, the keyboards are opposed to the mechanical switches to the diaphragm switches.
ACTUATION FORCEPressure required on a key to push it to its activation distance. The higher the force, the greater the feeling of “stiffness” of a key.
DISTANCE OF ACTIVATIONDistance traveled by pressing the key to consider the key pressed. The maximum distance for pressing a key is 4mm.


KEYBOARD LEXICONComputer color coding system. The RGB LEDs are able to provide illumination on a palette of 16.8 million colors for aesthetic purposes.
NUMBER OF HITCHESNumber of keystrokes: Membrane keyboards are designed to last between 1 and 5 million hits. Mechanical keyboards, these are tested to support up to 50 million keystrokes.
MACROSSequences of actions (key sequences, mouse clicks or expectations for example) that simplify the execution of repetitive tasks. You can also use the Macro Repeat feature to run a macro continuously and stop it at any time.
N-KEY ROLLOVERThe rollover meanwhile is slightly different. A keyboard that limits its rollover to 3 will allow the simultaneous activation of only 3 keys. This nomenclature is written as follows:
#KRO (where # is the number of keys allowed)
NKRO (where there is no limitation, a full rollover)
Many mechanical keyboards have a 6KRO, but it is possible to find 8KRO or NKRO. An NKRO is less common, but allows a variety of combinations that has almost no limit!
ANTI-GHOSTINGGhosting is the non-activation of a key pressed when other keys are. A membrane keyboard is reasoned in rows and columns, if you press simultaneously the three keys “Z” “S” and “D”, the controller will have no trouble identifying the keys “Z” and “S”. But he will not know if it is the “D” or “E” key that is pressed because it belongs to the same block.


DPI – SENSITIVITYMeans “dots per inch”. They match your mouse resolution. The higher this value, the more the mouse is able to record information over a given distance, which makes it more accurate.
ACCELERATION MAX – SPEEDMaximum speed that a mouse may experience before the sensor malfunctions.
These technical terms essentially measure the accuracy of your mouse.
POLLING RATE – REACTIVITYHow often the mouse will send its information to the computer through the USB port. A polling rate of 1000 Hz means that the mouse information (moves, clicks, etc.) will be sent to the system every 1 millisecond.
OPTICALThe optical sensor works by means of an LED that emits light on the surface on which the mouse rests and which transmits the movements to the sensor via the lenses. The movements are thus calculated and reproduced on the screen in a more or less precise and sensitive manner according to the number of DPI assigned to the sensor.
LASERThe LED is replaced by a laser wich reduces the area to be analyzed and therefore the latency between the movement and its retransmission to the screen. As a result, the cursor movement will be much more precise. The laser sensor has another important advantage: it works on reflective surfaces (a glass table, a painted desk or on a plasticized mouse pad) in contrast to the optical sensor.


FPSfirst-person shooter, Ex: Call of Duty; Counter Strike; Overwatch.
TPSThird Person Shooter – as opposed to FPS where the player sees his or her character from the back. Ex: Fortnite; GTA…
MMORPGMassively Multiplayer Online Role Playing Games (MMORPG), allow players from around the world to simultaneously access a persistent universe, the most famous representative being World of Warcraft. Ex: World Of Warcraft; Guild Wars.
Point and clickAdventure game, mainly on PC, where the player uses the mouse cursor to explore the sets and thus perform different missions and riddles. Ex: Syberia; The Secret of Monkey Island.
RPG“role-playing games” are games wich allow the player to embody a character who can gain experience and whose attributes will evolve throughout the game. Ex: The Witcher 3; Skyrim; fallout…
RTS “real-time strategy”, games to put in opposition to turn-based strategy games, which are often war games or simulation. Ex: Starcraft; Warcraft 3; Age of Empire
MOBAThis is a multiplayer genre, usually played with two teams of five players. The goal for each team is to destroy the main base of the opposing team, by means of the characters controlled by each player. Ex: League of Legends; Dota 2; Heroes of The Storm…
LANLocal Network Competition. Based on the LAN’s abbreviation, and means “Local Area Network”. If originally the term was used to describe a competition in “lan” (so without internet network), the term is still u sed to describe a gathering of players who play against each other (even if all the competitions of our days require internet). Ex: Lyon Esport; Dreamhack; Montpellier Esport Show; Gamers Assembly.
