It's not always easy to find serenity in your office. Especially when Bob is talking louder than a fire truck. With the Kalm, finding peace has never been easier.

You can listen to music or use your smart phone in nearly noiseless comfort. With active noise-canceling technology that blocks up to 90% of surrounding distractions the Kalm lets you focus on what's important. So whether you're on a call with your boss or listening to music, you won't hear the distractions! Plus, with three independent MEMS microphones (2 to cancel outside noise and 1 to hear you even better), you can be sure that you sound amazing.

Of course, there are some situations where you want to hear what's going on. For those moments, the Kalm has a handy button that lets you switch off noise cancellation and tune back into the outside world!

You get 20 hours of powered, noise-canceling use from one AAA battery. Battery dead? No problem. Just set it to passive mode. This lets you use the headset without noise-canceling so you'll never be without your headphones.

Compatible with iOS, Android, Blackberry, and Windows phones.
