Those who spend a lot of time on the phone during their work really appreciate the benefits of a headset. Especially since it leaves their hands free, which is essential for many purposes. But those who wear a headset all day demand high standards when it comes to comfort, safety and sound quality. Which is why Sennheiser Communications has developed headsets for the professional user that place special emphasis on comfort and safety. The 500 series offers the right model for every taste, regardless of whether the user prefers a binaural or monaural solution.
The new CC 515 is a monaural version, which makes it particularly light and comfortable to wear. This solution also allows you to keep in touch with what is going on around you. The headband can be adjusted independently on both sides for a perfect fit to the head and the unique balanced side support system provides additional stability. Unlike the otherwise identical model CC 510, the CC 515 has XL ear caps: 51 mm instead of the usual 42 mm ear caps makes for greatly improved comfort. Like the other models in the high-end series, the CC 515 has an ultra noise-cancelling microphone which filters out ambient noise and thereby ensures optimum clarity.
A unique feature of the Sennheiser Communications headsets in the 500 and 300 series is the ActiveGard? system to help safeguard hearing. The system cuts in before any potentially damaging acoustic burst can reach the ear. It not only reduces the dangerous energy of the sound, but eliminates it completely. As soon as the volume returns to a safe level, ActiveGard? restores the normal working volume and switches back to the monitoring mode.
Tests confirmed by the renowned Norwegian research institute Nemko Comlab show that ActiveGard? is superior to conventional systems. These merely chop off the peak volume without removing the energy of the sound pressure. As a result, the signal retains its dangerous energy, and annoying distortion may occur. Such systems offer considerably less safety than ActiveGard.
