Block out background noise when using the BlueParrott M300-XT Bluetooth headset. You'll have a small compact earpeice to wear for hours and block out 80% of noise callers would otherwise hear. Extended battery talk time up to 14 hours also gives you plenty of time to use the headset for calls and audio without having to recharge the M300-XT. Also, you'll have up to 300 feet of wireless range to walk away from your phone. So, if you leave your mobile phone in the car and step out of your car to deliver a package for example, you'll have plenty of range to keep your conversation going. To avoid using your phone and keep your hands free, you'll be able to mute/unmute from your M300-XT, speed dial your preferred contact or push to talk with coworkers.
