The Nighthawk’s 12 hours of talk time is more than double that of most in-ear Bluetooth devices that provide 5.5 hours on average. Don’t trust a Bluetooth earpiece that runs out before you do. With the Nighthawk worn on the chest area, the microphone is in the direction of the mouth, reducing ambient noise which enables transmission to be heard clearly. A preamp is also introduced inside the Nighthawk allowing optimal speaker output. Even in the loudest environment one can hear quality communication without a problem. The acoustic airtube earpiece reduces the user’s risk of radiation and allows for all day comfort and supreme sound quality.
