A stylized, lightweight behind-the-ear design is not only discreet, it is comfortable enough to be worn all day. A superior microphone and earpiece create a high-performance headset yielding great results for both traditional phone lines and IP telephony systems. The CS70N offers wireless freedom with no compromises. Includes the Plantronics HL10 handset lifter for remote call answer/end capability.
