Plantronics designs and manufactures a wide range of corded and wireless headsets for the office and mobile communcations market.
With the ubiquity of mobile headsets today, people now are accustomed to approaching someone talking that is wearing a visible headset. The person wearing the headset is likely talking to someone on a call, and not to anyone standing around him.
The Firefly Headset was an early attempt, before BT headsets were commonplace, to give observers a visual indication that the wearer was on a call. Our assignment was to retrofit an existing headset model (the m170) with a blinking light at the microphone boom tip. An equal challenge for ID, ME, EE, AE and MFG.
My contribution was the Mechanical Engineering of the new boom tip assembly and modified plastic parts.
