Connecting, putting on and using the headphones

  • 1/4" (6.35 mm) stereo jack plug, unbalanced (can also be connected to a 3.5 mm stereo jack socket by using the supplied adapter)
  • *4.4 mm stereo jack plug, balanced (Sennheiser CH 660 P, optional accessory)
  • *XLR-4 connector, balanced (Sennheiser CH 650 S, optional accessory)
• Connect the headphones to your audio source.
• Put on your headphones and then pull the ear cups down until they rest comfortably over the ears. Make sure you wear them the right way round by observing the "R" (right) and "L" (left) markings on the ear cup bands.
  
• For optimum sound quality, ensure that the ear cups are not covered.
  

Replacing the ear pads

For reasons of hygiene, you should replace the ear pads from time to time. Spare parts are available from your Sonova Consumer Hearing partner. To find a partner in your country, search at www.sennheiser-hearing.com/service-support.

• Grasp behind the ear pads and pull them up and away from the ear cups.
• Place the new ear pads onto the ear cups and attach the ear pads by pressing firmly around them.

The headband padding can be replaced by the repair service. Please contact your Sonova Consumer Hearing partner.

Changing the connection cable

• Make sure the "R" (right) and "L" (left) markings on the connectors match the markings on the ear cups. The marking on the connectors must point outward.
• Insert the connector until it locks into place with an audible click.
