Important safety instructions

Read this instruction manual carefully and completely before 
using the product.

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

Do not use the product if it is obviously defective or makes loud, 
unusual (whistling or beeping) noise. 

Only use the product in environments where Bluetooth wireless 
transmission is permitted.

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 good at low and medium volume 
levels.

The product generates stronger permanent magnetic 
fields that could cause interference with cardiac pace-
makers, 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.

Do not insert the earphones too deep into your ears and never 
insert them without ear adapters. Always remove the earphones 
slowly and carefully from your ears.

Keep the product, accessories and packaging parts out of reach 
of children and pets to prevent accidents. Swallowing and chok-
ing hazard.

Do not use the product in an environment that requires your spe-
cial attention (e.g. in traffic or when performing skilled jobs).

Preventing damage to the product and malfunctions

Always keep the product dry and do not expose it to extreme tem-
peratures (hairdryer, heater, extended exposure to sunlight, etc.) 
to avoid corrosion or deformation.

Use only attachments/accessories/spare parts supplied or rec-
ommended by Sennheiser.

Clean the product only with a soft, dry cloth.

WARNING

If abused or misused, the rechargeable batteries may leak. 
In extreme cases, they may even present a risk of:

• explosion,

• fire development,

• heat generation,

• smoke  or  gas  development.
