The Headset
The QuietComfort headset is attached to its control unit by a two-wire cable connected to both ear cups. The length of this cable is about 97cm (38") long so even if you are very tall, it's long enough for the control unit to be hooked up to the belt or placed inside a pocket. In fact, this cable actually extends right down to my knees!
From the control unit, a separate 37cm (15") single-wire cable extends out to a gold plated 3.5mm stereo plug. This is more than enough for most purposes. I found that with the control unit hooked to my belt, I can easily attach the plug to a Pocket PC in my shirt pocket!
The headset and its control unit
The headset itself was designed for absolute comfort. The large ear cups come with soft and very comfortable cushions and the headband is even padded! Although it looks heavy, the headset actually feels very light. You won't get a sore neck with this one! ;)
The headband at its maximum extension
At its shortest, the headband (above) is about 40.5cm (16") long from the center of one ear cup to another. It can be extended by an additional 7.5cm (3") for a maximum length of 48cm (19"). That is more then enough to fit everyone on the planet, big head or not.
