Using the headset
Connect the audio cable to the 2.5 mm jack socket 8 on the control unit I and to the corresponding jack socket on your mobile telephone.
You can adjust the volume of the mobile telephone via the headset’s control unit. However, the functions of the mobile telephone cannot be controlled via the headset’s control unit.
Operate your mobile telephone as usual and observe the instructions of the manufacturer.
The latest list of compatible mobile telephones is available on our website at www.sennheiser.com.
Connecting an additional audio player
The 3.5 mm jack socket 6 allows you to connect and listen to an audio player (not supplied) through the headset. For this purpose, the NoiseGard™ active noise compensation must be switched on.
CAUTION
Danger of accident due to reduced attention!
Listening to music or operating an audio device limits your attention and may cause accidents.
During flight operation, do not use the headset for listening to additional audio sources!
