Getting started/operation
In order to prevent distortions or mismatches that might damage the headset, plug the
product only into a proper headset connector.
If your audio device does not have a suitable jack to connect to the headset, please use
suitable adapters (not included).
• Switch off the audio device to which the headset is to be connected.
• Turn the volume control on the audio device all the way down.
• Connect the included connection cable to the connector (4) on the bottom side of the left ear
piece (note label "L" on the inner side of the carrying handle).
• Connect the plug (6) to the audio connector of your audio player (e.g., the port for a headset on
a tablet computer or mobile phone).
• Switch on your audio device.
• Use the "+" button or the "-" button on the control unit (5) to adjust the volume for audio play-
back (you may want to initially turn up the volume on the audio device). Audio playback can be
paused and resumed via the middle button.
On the back of the small housing is the microphone (a small hole in the housing). Do not
cover this.
Whether the buttons function with your tablet-computer or mobile phone depends on
the device.
• Three positions on the headset can be adjusted, so that the ear pieces of the headset fit properly.
1 = moving the carrying handle
2 = swivelling the ear pieces inward/outward
3 = turning the ear pieces forward/back
• Always wear the headset properly.
The left ear piece (with the connecting cable) is marked with "L", the right one with "R"
(respectively located on the inside of the carrying handle).
