As telecommunications technology keeps changing and spawning exciting new product lines in headsets, how do you keep up? Is an over-the-head or earbud design right for you? We have a quick solution. Just take a minute to scan the list of commonly used terms below, and we can give you a jumpstart on determining which Plantronics headset solution best suits you!

Amplifier
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 A20. Amplifiers are also included as part of a headset system, such as the S12 and S20. The CA10 is an amplifier for a cordless headset system.

Behind-the-head
Plantronics recently introduced the new, behind-the-head neckband accessory that adds a unique wearing style to DuoPro? (H181, H181N) and DuoSet? (H141/H141N) headsets. The neckband offers a fresh alternative for those looking for a contemporary wearing style.

Bluetooth
Bluetooth? is an amazing new wireless technology using short-range radio links that promises to eliminate the cables and wires that currently connect most computing and communications devices. At Plantronics, we're using this technology in such products as our new wireless mobile headset, the M3000.

Call Clarity
Proprietary Plantronics technology, Call Clarity is an electronic signal processing and noise reduction system found in our amplifiers that enhances transmit and receive quality.

Convertible
Convertible headsets offer the choice of two wearing styles, usually over-the-head for stability or over-the-ear for easy on/off convenience. These headsets can easily be "converted" from one style to the other in a few simple steps. Plantronics convertible headsets include the DuoPro? (H171/H171N), the DuoSet? (H141/H141N), and the M170/M175 mobile headsets.

Earbud and In-the-ear style
Earbud style describes a small, discreet headset with a speaker that fits in the ear and the microphone positioned along the cord. The H132N office headset, as well as the MX100 and the M205 mobile headsets are some examples.

Firefly
Firefly is the unique in-use indicator light that lets others know you are on the phone. No more interruptions! You can find it on the CT12 cordless headset telephone.

Noise-canceling
Noise-canceling refers to a microphone design that greatly reduces the transmission of background noise, enhancing headset sound quality. Noise-canceling headsets are especially effective for offices with employees in close proximity to one another. In mobile applications, noise-canceling microphones reduce background noise in cars, airports or on the street.

Over-the-ear
Over-the-ear is used to describe Plantronics headsets that have over-the-ear earloops or other devices to hold headsets in place. TriStar, Mirage? and M130 are some examples.

Over-the-head binaural
When it's important to help filter or screen out background sound, you should consider over-the-head binaural headsets, such as the Supra (H61/H61N) and Encore (H101/H101N). This style provides sound transmission to both ears.

Over-the-head monaural
Plantronics monaural headsets, on the other hand, deliver sound to one ear. Unless it says otherwise, Plantronics headsets are monaural.

Quick Disconnect
On H-Series headsets, the Quick Disconnect? (QD) is the connector at the end of the headset cable that lets you disconnect your headset from an active call when you need to grab a fax or file, then easily reconnect. With the QD, there's no need to put the call on hold or remove your headset.

Sound Guard Plus
An automatic gain control system found in Plantronics amplifiers, Sound Guard Plus provides natural voice tone and removes loud tones, as well as occasional noises and crackles on the line.
