Important safety instructions

X Read this instruction manual carefully and completely before using the

product.

X Always include this instruction manual when passing the product on to third

parties.

X Do not use an obviously defective product.

Preventing damage to health and accidents

X 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 good at low and me-

dium volume levels.

X Keep the headphones at least 10 cm/3.94” from cardiac pacemakers or im-

planted defibrillators. The headphones contain magnets that generate a

magnetic field which could cause interference with cardiac pacemakers and

implanted defibrillators.

X Keep the product, accessories and packaging parts out of reach of children

and pets to prevent accidents and choking hazards.

X Do not use the product in situations which require special attention (e.g. in

traffic or when performing skilled jobs).

Sennheiser.
