The new MicroCom PMC-HS900XRS Wireless Headset Single-Ear (All-in-One) combines the great sound quality, excellent range, and budget-friendly price point of MicroCom XR with the comfortable fit, exceptional noise isolation, and flip-up microphone muting technology of the SmartBoom PRO headset, but without the wire. The Single-Ear model features an internal antenna and field replaceable battery with an operating time of 7 hours. Compatible with the popular two-channel MicroCom 900XR beltpacks, users can mix and use a combination of MicroCom XR wireless all-in-one headsets and traditional MicroCom XR beltpacks as part of the same system to meet the needs of different applications. A lightweight and adjustable design allows for comfortable all-day wear and the headsets collapse for easy storage and travel when your work is done. Also available with the new MicroCom headset is the industry's first drop-in charger for an all-in-one style headset. The entire headset can be placed on the charger without having to remove the battery or plug in a cord. Six additional batteries (sold separately) can also be dropped in for simultaneous headset and spare battery charging capabilities.
