Voyager 4245-M Office is a pleasure to wear-the lightest Bluetooth headset of its kind. Everyone can move freely and collaborate in comfort, all day. Because losing connection with a customer is bad for business, Voyager 4245 has continuous battery life for unlimited talk time. If a battery runs low, it can be swapped out mid-call-so conversations stay on track, and customers stay happy. Three wearing options on a single device keep your teams happy too - and makes for easy ordering and stock control. And we topped it all off with high-quality audio, so you get a headset that delivers an all-around great experience
