How secure is the Sennheiser OfficeRunner*

There is some question of how secure the signal is from this type of headset.

DECT technology uses encryption to protect the signal. DECT technology is a standard just like Bluetooth or wi-fi.

The Sennheiser headsets are actually more secure since they requires physical contact to make a connection.

Sennheiser’s wireless headsets meet the same security standards as all other DECT headsets.

However, the official DECT security list is a paid subscription which Sennheiser has not paid to have a listing on, which is why Sennheiser headsets are not currently listed.
