"As a dental office manager it is important to keep abreast of what's going on with patients and staff at all times. These radios are the best thing ever! Not only do they work well but they are comfortable to wear. I have left the office many times still wearing my radio and headset! Thanks for providing superior customer service as well as an excellent product!"

Coiled Tube Color


The Sentinel features less wire than other 2-wire kits. One wire leaves the radio and runs to a microphone push-to talk unit; the earpiece wire attaches at the microphone/push to talk unit near the lapel and runs under the shoulder to the back of the neck. The audio quality for the Sentinel High Noise Earpiece is excellent in extreme sound pressures. The Sentinel features a large PTT which lies flat; this means it is easy to find and that you can simply push on it rather than having to grab the entire PTT unit. A step saved you'll be thankful for when your hand and your mind are engaged by an unruly guest!

With this earpiece you can talk into your radio at a conversational tone and have crystal clear communication even if you can't hear yourself talk. The Sentinel HN uses Kevlar-reinforced wiring and top quality strain reliefs. It was designed for those in a high noise environment, so it will survive in even the roughest work environment.
