The Concierge is a very comfortable coiled tube earpiece that is comfortable durable and secure. The Push-To-Talk is conveniently located in line with the earpiece. The single-wire design is excellent for casinos, hotels, event management, offices, and other applications where discretion is not as important, especially where the earpiece will be worn outside of the clothing because it has less wires to manage than a two-wire kit. These are very durable and feature a one-year no questions asked warranty.
