The Plantronics CS55 Wireless Office Headset System brings the ultimate in mobility and sound quality for hands-free conversations to your phone. Totally wireless, the CS55 gives you up to ten hours talk time and the wireless convenience to roam up to 300 feet while having secure conversations. The new 1.9GHz DECT frequency means less interference with other wireless devices. The headset continuously charges in the cradle, and when in use, taking or ending a call is as simple as pressing a button. The optional HL10 automated handset lifter allows calls to be answered remotely.

Compatible with typical corded office or PBX-based phones, the CS55 headset can be worn on either ear or over-the-head for maximum, long wearing comfort.

• Walk and talk up to 300 feet away from your desk
• Ten-hour continuous talk time, then recharge 80% in 1.5 hours
• Clearer calls, and less interference from 1.9GHz DECT
• Convertible headset can be worn on either ear and quickly converts between over-the-ear and over-the-head wearing. Behind-the-neck headband option available for extra stability during fast head movement

• 64-bit digitally-encrypted signal. Nobody can listen in on your calls
