As headset and wireless technology keeps changing and spawning exciting new product lines in headsets, how do you keep up? This glossary contains explanations of commonly used headset terminology including industry, technical, and marketing terms used across Jabra and Plantronics line of headsets.

A2DP
Abbreviation for "Advanced Audio Distribution Profile". A2DP is a Bluetooth profile that transmits stereo sounds. Also referred to as the AV profile, it is designed to transfer a stereo audio stream (such as music) from an mp3 player to a headset or car radio. Plantronics products such as Voyager Legend and the BackBeat family support the A2DP profile.

ACTIVE NOISE CANCELLATION
Also known as active noise control (ANC) or active noise reduction (ANR), it is a method for reducing unwanted sound by the addition of a second sound ("anti-noise") specifically designed to cancel the first.

AMPLIFIERS
Amplifiers make sound louder. This technology enables headsets to be used with corded phones and phone systems. Plantronics manufactures and markets a wide selection of corded, stand-alone amplifiers, such as the M12 and DA82. In addition to amplifying sound, Plantronics amplifiers and audio processors usually include additional features to enhance communication, including mute and volume controls.

ANALOG
In regards to Plantronics products, it refers to computer headsets that plug directly into a computer's sound card with two round 3.5 mm plugs.
