Tech Explained: Headsets / Audio

Listen (yep, we went there), who needs wall hacks when you've got jaw-droppingly good crystal-clear sound? Seriously though, we don't take high-quality audio lightly. We've spent countless hours trying numerous headsets & headphones, pushing them to their absolute limit to fine-tune our range and making sure that we only provide you with the very best audio gear. There's no deadbeats here.

Speakers

Drivers

The speaker drivers are the round elements that many call the actual speakers. These typically come in a cone or dome shape. The part of the headset that moves back and forth to make the sound.

Frequency Response

The range of bass, mids and treble the speakers can output. the first number represents the bass and the second represents the treble. 20Hz - 20,000Hz is the standard for headphones.

Sensitivity

Determines how sensitive the volume control is. Low sensitivity (86db) would require turning the knob more to increase volume whereas high sensitivity (110dB) would require less turning. In short, high sensitivity = louder volume.

Impedance

Describes the amount of power needed to deliver high audio quality. The most common headset impedance is 32 ohms. The higher the impedance the more accurate and vivid the sound gets.

Microphone

Polar Pattern

The polar pattern of the microphone refers to it's abilities on picking up sound. The patterns most commonly used are;

Polar Pattern: Omnidirectional

Picks up sounds from all directions with equal gain. Allow for greater flexibility in sound pick up as the user can speak into any part of the microphone.

Polar Pattern: Bidirectional

Also known as a "figure-of-eight microphone". It is known as this as it is great at picking up sound from the front and back, but poorly from the sides.

Polar Pattern: Unidirectional

Only pick up sound with high gain from a specific side or direction of the microphone. Great for team comms as it cut outs most background noise.

Polar Pattern: Cardioid

Pick up sounds well from the front and sides but poorly from the rear.

Polar Pattern: Super-Cardioid

Same as the cardioid microphone but have a much narrower area of sensitivity. Results in improved isolation and higher resistance to feedback. Sound rejection from the back is compromised so unwanted noises may occur such as having the mic positioned between the user and the keyboard, the clicking of the keys would be picked up by the microphone.

Frequency Response

The frequency response is the frequency-specific output sensitivity of a microphone. It details the relative output levels of the sound/audio frequencies a mic is able to reproduce. The standard for this is 20Hz - 20,000 Hz.
