How is this Possible?
The study shows three primary drivers of productivity provided by headsets:

• Flexibility increases - The employee can move much more freely and has full use of both hands. Furthermore, phone communication becomes a natural part of the other processes in the job like operating the PC. This means that you can solve many more tasks while talking on the phone. The study shows that 8 out of 10 feel more efficient and the feeling of being more efficient is very beneficial for managers and employees' ability to do well and have high self confidence and motivation in the job.

• Work life quality increases - Many have adapted their motion patterns and work routines to the phone handset and its apparent limitations. This results in uncomfortable and often harmful postures that can inflict headaches and pain in the neck and the shoulders, when you try to solve more tasks at the same time, e.g. when the handset is cradled between head and shoulder in order to free both hands for typing. The headset is a known "pattern-breaker" that removes these hazards without introducing new ones. To the user this means a safer and more comfortable work day with less pain and strain and improved ergonomics and raised comfort levels have a positive influence on performance.
In a recent user study focusing on ergono-mics, discomforts diminished significantly for half of the persons who changed from handset to headset and for 1 out of 4, neck and back pains totally disappeared.

• Customer service improves - With a wireless headset you not only free your hands but are also able to get up and move around. This freedom expands task-solving capabilities when you can go and pick up a binder or talk to a colleague for advice. It also allows you to move both the upper and lower body more freely, which is ergonomically beneficial. This paves the way for a more motivated and service-minded work day and a likely reduction in turnover rates.
