From the Manufacturer:
Gets your message through clearly
Sennheiser’s ultra noise-cancelling microphone on the SC 668 has been improved to optimize speech transmission and intelligibility in busy contact center and office environments by reducing unwanted background noise.
Stunning looks. Stunning sound.
With a comfortable fit that lasts all day and a solid sense of quality, the SC 668 is built to sound superb, look stunning and outlast the competition - in even the toughest contact center or office environment. It’s a headset that says you put your people and customers first.
Adjustable and lightweight for all-day use
SC 668 is designed for long-hours use throughout a working day – and that means everything focuses on wearing comfort: from the large leatherette ear-pads to the unibody headband construction for maximum strength at stress points to ensure a truly comfortable communications experience.
Sennheiser’s Easy Disconnect plugs are ideal for contact centers and hot desking offices, where users frequently change shifts or switch between workstations.
With their simple, quick release mechanism, durable Easy Disconnect plugs are designed to withstand the repetitive plugging and unplugging of shift changes.
