Attention! High volume!

This is a professional pair of headphones. Commercial use is subject to the rules and regulations of the trade association responsible. Sennheiser, as the manufacturer, is therefore obliged to expressly point out possible health risks arising from use.

This system is capable of producing sound pressure exceeding 85dB(A) . 85dB(A) is the sound pressure corresponding to the maximum permissible volume which is by law (in some countries) allowed to affect your hearing for the duration of a working day. It is used as a basis according to the specifications of industrial medicine. Higher volumes or longer durations can damage your hearing. At higher volumes, the duration must be shortened in order to prevent damage.

The following are sure signs that you have been subjected to excessive noise for too long a time:

A You can hear ringing or whistling noise in your ears!
You have the impression (even for a short time only) that you can no longer hear high frequencies!

Adjusting the headband

For good transmission quality and best possible comfort, the headband has to be adjusted to properly fit your head. To do so, adjust the headband via its snap-in locking mechanism.

Folding up the headphones

For space-saving transportation, the headphones can be folded up in three different ways:

1. To fold up the headphones as compact as possible, tuck the earcups between the headband (variant A and B).

Note:

To fold up the headphones as shown in variant B, pull out the headband completely.

1. To fold up the headphones as flat as possible, the earmups can be rotated by 90^ .

Cleaning the headphones

To clean the headphones, use a soft, damp cloth. If necessary, the headphones can be cleaned with soapy water (use a mild cleanser such as washing-up liquid).

Note:

Never use solvent-containing cleansers.

Replacing spare parts

Available accessories and spare parts

• Ear cushions
• Headband padding
• Connecting cable

Replacing the ear cushions

Grasp behind the ear cushions and pull them up and away from the earcups. Slide the new ear cushions onto the earcups.

Replacing the headband padding

Pull the Ziploc type fastening strips of the headband padding apart, as shown in the diagram on the left, and remove the worn headband padding.
Put the new headband padding around the headband.
Pull the two edges of the headband padding together so that the fastening strips slightly overlap.
Join the fastening strips.

Replacing the connecting cable

Replace the connecting cable if it is damaged. To do so, please proceed as follows:

Remove the ear cushion. Grasp behind the ear cushion and pull it up and away from the earcup.
Loosen the screw 1 and remove it.
Remove the cover from the earcup 2.
Pull the connector 3 out of the socket.
Remove the antikink protection of the connecting cable from the holding device 4.
Insert the antikink protection of the new connecting cable into the holding device.
Plug the connector 3 of the new connecting cable into the socket as shown in the diagram on the left.
