Motorola HK100 headset delivers hands-free phone calls and plays music stored on your smartphone with stunning audio performance. With noise cancellation capabilities, callers will hear only you, and with a wide roaming range your phone can stay in one room while you roam freely throughout the house or yard. Voice prompts help you make the most of up to 12 hours of talk time on a single charge. The device will tell you when you’re connected, remaining talk time, and if mute is on. Motorola's TrueComfort design helps redistributes weight to make long conversations light and comfortable for your ear.
