Headset Terminology
• 1.9GHz — The 1.9GHz frequency band is dedicated to voice communications (all wireless DECT phones and headsets), and it is considered more secure than other communication frequencies.
• 2.4GHz — This frequency band is used for both data and voice communications (Bluetooth devices and headsets). Most wireless computer devices operate on the 2.4GHz frequency band.
• 2.5mm — 2.5mm plugs are standard round plugs used in consumer-type telephones and in the past mobile phones for headset connections.
• 3.5mm — 3.5mm plugs are standard round plugs used for headset connections in digital music players (such as MP3 players) and in some mobile phones.
• 64-bit encryption — See Encryption.
• 128-bit encryption — See Encryption.
• A2DP (Advanced Audio Distribution Profile) — A2DP is a Bluetooth profile designed to transmit stereo audio. It transmits a stereo audio stream (such as music) from devices that use the A2DP audio profile, such as MP3 players and many GPS systems, to a headset, speakerphone or car radio.
• Amplifier — Amplifiers are designed to make sounds louder. Amplifiers allow headsets to be used with telephone systems that are not pre-amplified for headset use (i.e. do not have a headset port). VXi manufacturers two types of amplifiers: the Everon (a multipurpose amplifier that can be used with most contact center and office phone systems) and the Console (a specialized amplifier that uses a stereo plug connection to connect to specific phone systems).
• Analog — Analog audio is audio in which the sound is converted into electrical energy when it is transmitted. To listen to the audio, the electrical energy is converted back into sound waves.
• Base Station — The charging base for a wireless headset. The base station provides connectivity from the phone system to the headset, and it also charges the headset.
• Behind-the-neck — A headset wearing style where the headband sits behind the user's head/neck.
• Binaural — Two-ear. Headsets with two earpieces/receivers are called binaural headsets. VXi's Passport 21 headset is a binaural headset.
• BlueParrott — VXi BlueParrott is VXi's line of Bluetooth headsets.
• Bluetooth — Bluetooth® is a short-range wireless connectivity standard. Bluetooth is the standard adopted by mobile phone manufacturers for headset connectivity. Most Bluetooth devices have a range of approximately 10 meters (about 30 feet). The VXi BlueParrott line of headsets uses Bluetooth to connect to Bluetooth-enabled mobile phones and devices (such as dongles, laptops and computers). Bluetooth devices operate on the 2.4GHz frequency band.
• Convertible — The description of a headset that allows the user to change the wearing styles of the headset. The VXi Tria headset is a convertible headset. It includes three wearing styles: over-the-ear, over-the-head and behind-the-neck.
• Corded — Corded refers to a headset that connects to a telephone system using a cord.
• Date Code — The date code is a four digit code (i.e. 12/10) found on the serial number of most VXi products that indicates the commencement date of the product's warranty period.
• DECT — DECT stands for Digitally Enhanced Cordless Telecommunications. The current DECT standard is DECT 6.0, and it operates on the 1.9GHz frequency band. The VXi V100 wireless headsets system is a 1.9GHz DECT 6.0 headset system.
• Direct Connect (DC) — Direct connect refers to the method to connect to a phone system that has a headset port and does not require an amplifier. A Passport DC headset used with a direct connect cord (1026, 1027 or 1029 depending on the phone system) allows users to connect directly to the phone system.
• Dongle — A dongle is an adapter used with a computer to provide additional functionality that is not built into the computer. Most commonly, dongles refer to Bluetooth dongles. A Bluetooth dongle plugs into a USB port on a computer to allow users to connect Bluetooth headsets to computers that do not have Bluetooth embedded.
• DSP (Digital Signal Processing) — Digital signal processing is used mainly in USB and wireless headsets and devices to improve audio quality. The VXi X200 USB Adapter includes DSP to provide optimization for Unified Communications.
• Earhook — A headset accessory that attaches to the headset and allows the user to wear the headset by placing the earhook over the ear. VXi offers a flexible earhook that allows the user to adjust the fit of the earhook to ensure the most secure and comfortable placement.
• Encryption — Encryption is the process of scrambling and unscrambling a transmission between two devices to create secure communications. The most common encryption methods are 64-bit and 128-bit. Bits refer to the number of keys that are used to perform the encryption. A higher number refers to a higher level of encryption, thus creating a more secure communication.
• Handset Port — The handset port is the port on the phone where the handset's curly cord connects to the phone. For phone systems that do not have a headset port, VXi's Everon amplifier (for corded headsets) or V100 wireless headset system can connect via the handset port.
• Headset Port — Most recently manufactured office phone systems have a port that is dedicated specifically to connect a headset. The headset port is typically a 2.5mm plug or a modular plug (RJ9). VXi offers various direct connect cords to connect a headset to the headset port.
• HFP (Hands Free Profile) — HFP is an extension of the Bluetooth HSP profile. HFP includes functionality such as voice dialing, answer/end calls, redial and call transfer.
• HSP (Headset Profile) — HSP is a Bluetooth profile that enables headsets and headphones to be used with Bluetooth-enabled computers and audio devices. HSP includes voice and mono music.
• Monaural — One-ear. Headsets with one earpiece/receiver are called monaural headsets. VXi's Passport 10 headset is a monaural headset.
• Lifter — A lifter (also referred to as a handset lifter) is a device that allows wireless headset users to answer their phones remotely.
• Multipoint — Multipoint is a Bluetooth technology that allows a single headset to actively work with two paired devices (i.e. two mobile phones, a mobile phone and a Bluetooth-enabled desk phone, etc.). Headsets that do not have multipoint can only be used with the headset with which it is paired. For more information on using Multipoint, see our FAQs.
• Noise-canceling — Noise-canceling describes a headset microphone that reduces ambient background noise. Noise-canceling headsets are ideal for loud environments, such as contact centers or open concept offices where employees are located close to each other. Noise-canceling Bluetooth headsets are also extremely useful when using a Bluetooth-enabled mobile phone in a noisy environment such as the cab of a tractor trailer, in the car, at the airport, in a warehouse, at a construction site or on city streets. All VXi headsets are noise-canceling.
• Over-the-ear — Over-the-ear is a headset wearing style that allows the user to wear the headset using an earhook which goes over the ear. The V100 wireless headset system, the VXi Tria headset and the VXi BlueParrott Xpressway all offer an over-the-ear wearing style.
• Over-the-head — Over-the-head is a headset wearing style where the headset's headband rests on top of the user's head. Over-the-head headsets can be monaural or binaural.
• Pairing — Pairing refers to the process of creating a connection between a wireless headset and a phone or other audio device (i.e. a computer). In order to use a Bluetooth headset, it is necessary to pair the headset with the mobile phone or Bluetooth with which the headset will be used.
• Pairing Mode — Pairing mode is the mode on a Bluetooth headset and on a Bluetooth-enabled device that allows the headset and device to be paired. See our FAQs for an explanation of how to pair a VXi BlueParrott headset with a Bluetooth-enabled device.
• Passkey — During the pairing process, the Bluetooth-enabled device will normally ask for a Passkey to complete the pairing process. The Passkey for VXi BlueParrott headsets is 0000.
• Passport — Passport is VXi's line of headsets designed for the contact center and office environment. VXi Passport headsets allow interchangeability with VXi, Plantronics and GN Netcom equipment.
• QD — See Quick Disconnect
• Quick Disconnect — A Quick Disconnect (QD) is a connection that is found on most VXi headsets and cords. The QD allows the user to easily connect or disconnect a headset to an amplifier or direct connect cord. This allows the user to be able to walk away from the desk to get a file or consult with a colleague without having to take the headset off. VXi headsets have QDs that will connect to VXi, Plantronics and GN Netcom equipment.
• Range — Range is the distance that a user can walk away from the device with which their headset is paired. In the case of a Bluetooth headset, the device is typically a Bluetooth-enabled mobile phone. In the case of a wireless office headset, the device is typically a base station. The VXi BlueParrott line of headsets have a range of up to 66 feet, and the VXi V100 wireless headset system has a range of up to 300+ feet.
• Receive — Receive is the sound that the headset user hears. By increasing receive volume, the sound in the receiver/speaker will increase. Changing the receive volume will not affect the ability of the person on the other end of the call to hear the headset user's voice.
• Receiver — Receiver refers to the headset's ear piece or speaker.
• Remanufactured — For a VXi product, remanufactured means that the headset has been factory tested, evaluated using a multi-point inspection process and returned to a "like new" condition, complete with new ear cushions, windscreen, and battery (if applicable).
• RJ9 — RJ9 is a term to describe a standard, modular plug that most office telephone systems use. Most VXi amplifiers and direct connect cords use RJ9 plug connections.
• Sidetone — Sidetone is the sound of the headset user's own voice in through the receiver when using the headset. In natural speech, people can hear themselves speaking. Due to the fact that the headset's receiver is covering one or both ears, it is sometimes necessary for headsets and/or phone systems to generate sidetone through the receiver so that the speech conversation sounds natural to the headset user.
• Soundcard — A soundcard is a computer component that processes and reproduces the sounds generated by the computer and the applications. A headset soundcard connection typically consists of two 3.5mm plugs (one for the speakers/receivers and one for the microphone). These plugs connect directly into the soundcard. This connection was the primary means for connecting a headset to a computer prior to the introduction of USB headsets.
• Stereo — Stereo means sound that is sent separately to the right and left receivers/speakers in a binaural headset. In mono headsets, the same sounds are sent to the right and left sides.
• TalkPro — VXi TalkPro headsets are VXi's line of headsets designed to be used with speech recognition applications.
• Transmit — Transmit refers to the headset user's voice being transmitted via the microphone. Increasing transmit volume increases the volume of the speaker's voice. Transmit does not affect what the headset user hears.
• USB — USB is short for Universal Serial Bus. USB is a means of connection that is used on most computers to connect a wide range of devices from headsets to printers. VXi offers two USB cords — the X100 and X200 USB Adapters — that allow users to connect VXi Passport or Tria headsets to the computer to be used with Unified Communications, softphones and other voice-enabled applications.
• VoIP — VoIP is the acronym for Voice over Internet Protocol. VoIP describes a method of transmitting and receiving voice and phone calls over the Internet.
• Wideband — The human voice has a frequency range from 80 to 14,000 Hz. Traditional PSTN telephone networks limited the voice frequency from 300 to 3,400 Hz, which lessens the audio quality of conversations. With the advent of VoIP, greater bandwidth has become available to transmit a wider frequency range. This standard is now referred to as wideband, which ranges from 30 to 7,000 Hz. In order to benefit from wideband audio, both phone systems must be wideband together with the headsets and devices (amplifiers, USB cords, etc.) being used.
• Windscreen — Windscreen refers to the foam piece that covers the microphone. The windscreen prevents breath "pops" from reaching the microphone, which improves overall sound quality.
• Y-cord — A Y-cord is a cord that allows two headsets to connect to the same phone system. Y-cords are typically used for training.
