Important safety instructions

Read this instruction manual carefully and completely before using the product.
Always include these safety instructions when passing the product on to third parties.

Preventing damage to health and accidents

Protect your hearing from high volume levels. Permanent hearing damage may occur when headphones are used at high volume levels for long periods of time. Sennheiser headphones sound exceptionally low and medium volume levels.

The product generates stronger permanent magnetic fields that could cause interference to cardiac pacemakers, implanted defibrillators (ICDs) and other implants. Always maintain a distance of at

least 3.94" (10 cm) between the product component containing the magnet and the cardiac pacemaker, implanted defibrillator or other implant.

• Keep the product, accessories and packaging parts out of reach of children and pets to prevent accidents. Swallowing and choking hazard.
  Do not use the product in an environment that requires your special attention (e.g. in traffic).

Preventing damage to the product and malfunctions

Always keep the product dry and do not expose it to extreme temperatures (hairdryer, heater, extended exposure to sunlight, etc.) to avoid corrosion or deformation.
Do not place your headphones on a glass dummy head, chair armrest or similar objects for long periods as this can widen the headband and reduce the contact pressure of the headphones.
Use only attachments/accessories/spare parts supplied or recommended by Sennheiser.
Clean the product only with a soft, dry cloth.

Intended use/Liability

These open, dynamic headphones have been designed for home use with high-quality audio systems.

It is considered improper use when the product is used for any application not named in the corresponding product documentation.

With powerful bass, seductive timbres and breathtaking clarity, the HD 660S lets you experience the pure joy of music. The Sennheiser HD 660S will inspire you.

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)

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.

For reasons of hygiene, you should replace the ear pads from time to time. Spare parts are available from your Sennheiser partner. To find a Sennheiser partner in your country, search at www.sennheiser.com.

Grasp behind the ear pads and pull them up and away from the ear cups.
