Considering the ergonomic and efficiency benefits, a headset makes all the sense in the world. Our competency in

electronic communication and our commitment to comfort, safety, and quality make Sennheiser Communications an

excellent choice. Yet we believe in coming full circle with our innovations and supporting our customers with

accessories that make sense; like the

Sennheiser Communications Universal Interface box.

A brief description: a UI box works as a connector between your handset and headset. At the

touch of a button, a

passive box will allow you to easily switch back and forth between the handset and headset

or even integrate a PC into the system if you wish. But it doesn’t stop there: you can choose an

active box with

additional features that will regulate different volume levels and improve speech intelligibility – automatically. These

boxes are absolutely user-friendly because they are easier to set up than traditional boxes.

Without a universal interface: the absence of a UI box means that the user has to connect the

headset directly to the telephone. This does not allow for switching between the headset and handset, unless the

phone has a designated headset connection port. In addition, special care has to be taken to ensure that the cables

for connecting phone and headset are correctly matched. To receive additional assistance in choosing the correct

connection, please consult the Headset Selector at www.sennheisercommunications.com.

Comfort

In the UI 750 and UI 740 Dynamic Volume

Control™ raises and lowers the volume of

every incoming phone call to the user’s

preselected personal comfort level. For UI

730 and UI 720 there is an incoming

volume control button for manual volume

adjustment.

Convenience

At the touch of a button the

microphone can be muted for private

side conversations. A second switch

enables changing between handset

and headset.

Sound quality

The Sound Clarity System™ enables the user to significantly

improve speech intelligibility when receiving calls from very

noisy environments, such as a mobile phone in a moving car,

a poor long distance call, a noisy production facility, or a noisy

office environment. Based on the same technology used in

advanced digital hearing aid technology, this function reduces

the background noise and enhances the voice of the person

calling at the same time (includes UI 740).
