Why Might You Consider Headsets an Important Component of your Phone System?

Avoid or Reverse Workplace Injury
"Scrunching" the phone between your shoulder and ear leads to neck pain and headaches. If you want to be able to multi-task safely, consider using a headset.

Improve Productivity
Studies suggest that headset use increases employee productivity dramatically. Normally time-intensive tasks like checking reference materials while on the phone were performed more rapidly and proficiently with headset usage.

Road Safety
While studies have show that the real danger of using cel phones while driving is the distraction of a driver's attention to the road, many states have outlawed using a cel phone while driving unless you are using a hands-free device, such as a headset.

We offer new headsets from GN Netcom, Inter-Tel and Plantronics.
