Cobra headsets excel in quality and innovation while meeting strict handsfree driving law guidelines and regulations. The Cbora Deluxe Plus Bluetooth wireless technology enabled handsfree headset features a professional grade noise-canceling flexible boom microphone that eliminates almost all background noise. Cobra's high quality headset will kieep you talking, working, and/or driving conveniently even in noisy environments. With a talk time of 20 hours and a standby time of a whopping 400 hours, this bluetooth headset will be ready for you whenever you need it the most--for business or personal use. There is a rubber headrest on the side opposing the boom microphone so the headset rests comfortably on your head while still allowing you to hear outside noises if needed, such as sirens or someone calling your name. An easy on/off button allows for efficient answering whenever your hands aren't free to hold up a phone to your ear.
