The Concierge is a very comfortable coiled tube earpiece that is very durable and secure. The Push-To-Talk is conveniently located in line with the earpiece. The single-wire design is excellent for event management, hotels, offices, and other applications where discretion is not as important. In these types of settings there is the option to wear the earpiece outside of the clothing because it has fewer wires than the two-wire kit, making it easier to manage. These feature a one-year, no questions asked warranty.
