If you have to compete with wind, vehicles, loud machinery or other people when you make a call, this headset will solve your problem. The company crossed their own proprietary knowledge with military-grade “noise shield” technology approved by DARPA (Defense Advanced Research Projects Agency), the U.S. Department of Defense’s independent research branch.
The headset interprets the frequency of distracting sounds and emits sound waves that are a nearly exact negative frequency, effectively canceling out the interference.

The Jawbone Bluetooth headset gives you about 6 hours of talk time or 120 hours of standby time between charges. It comes with a battery strength indicator so you won’t be taken by surprise.
The unusual layout of the buttons takes some time getting acclimated to, but once you get the hang of it, this headset gives you great results. It retails around $120, but it’s well worth it if you often find yourself making phone calls in noisy environments.
