Your HD 660S

The HD 660S retains all the virtues of its legendary predecessor, the HD 650, but also represents a decisive step forward technology-wise. Thanks to advanced simulation possibilities, our engineers were able to further optimize the magnet system and the shape of the diaphragm.  In terms of sound, the HD 660S sets a new benchmark in its class and masters the balancing act between perfect control and fascinating musicality in a playful way.

A: Connecting the headphones

• Select the suitable connection cable and, if necessary, an adapter for your audio source to which you want to connect the headphones, and change the connection cable as described in section C:
• 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
• XLR-4, balanced (Sennheiser CH 650 S, optional accessory) Connect the headphones to your audio source.

B: Putting on the headphones and using them

• 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.

C: 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.
