There are a number of different types of security earpieces that can be chosen and worn by a security professional, and the type used typically depends on a number of factors. In general, there are two major categories for these devices: wireless and wired. Within these two basic categories, however, there are a number of different models and versions available. The type of security earpiece a professional chooses is often based on the needs of that individual and the level of secrecy he or she wishes to maintain with regard to the earpiece.
A security earpiece is a device worn around or in the ear which is connected to a two-way radio or similar device. This is commonly worn as part of a set with a microphone and receiver to allow a person to receive and send messages to other individuals who are also wearing similar earpieces. These devices are often used by security personnel and bodyguards such as law enforcement officers, the US Secret Service, and private personal security professionals. A security earpiece is typically either a wireless or wired device, with different models available of each type.
Both a wireless and a wired security earpiece can come in different models, usually either as an earpiece worn over the ear or a small earbud placed just within the entrance to the ear canal. Wireless devices of this type are often worn for extra secrecy, to allow a person to wear such an earpiece without it being readily apparent to observers. These devices are often earbuds that receive a signal wirelessly; a separate microphone is often worn on a lapel or at the end of a sleeve. The wearer can then speak into the microphone to send messages, while receiving messages in the wireless security earpiece.
A wired security earpiece will typically work in a similar way, though a wire connects the earpiece to the receiver. This wire can be clear to make it more difficult to notice, and often loops around the back of the ear to remain out of the way while worn. These types of earpieces often come in one-wire, two-wire, or three-wire versions. One-wire earpieces consist of only an earpiece without a microphone, two-wire devices have an earpiece and a second wire connected to a microphone that is often connected to a lapel or sleeve. A three-wire security earpiece includes the earpiece and microphone that is typically worn on the lapel, and then features a third wire that connects to a device on the wearer’s hand that allows him or her to activate the microphone inconspicuously.
