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. Head-

phones of the Sennheiser brand sound exceptionally good even at

low and medium volume levels.

▷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.

▷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 (earbuds

and charging case) 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 chok-

ing hazard.

▷Do not use the product in an environment that requires your spe-

cial attention (e.g. in traffic). Especially the product’s active noise

cancellation can make ambient noise inaudible or drastically

change the perception of acoustic warning signals.

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. The normal operating tempera-

ture is from 0 °C to 40 °C/32 °F to 104 °F.

▷To avoid loud, unusual (whistling or beeping) noise and to ensure

proper noise cancellation, do not cover the microphone openings

of the active noise cancellation circuitry located on the outside of

the earbuds.

▷Use only attachments/accessories/spare parts supplied or rec-

ommended by Sonova Consumer Hearing.

▷Clean the product only with a soft, dry cloth.

Safety instructions for lithium-ion rechargeable batteries

Notes on the ingress protection rating of the earbuds

The earbuds feature an IPX4 ingress protection rating which means

they are protected from the ingress of water (protection class

according to International Protection Marking (IP code), IEC standard

60529, tested under laboratory conditions).

The earbuds can be used in the rain, for example. However, they are

not suitable for immersion in water or for wearing in the shower. In

case of permanent moisture/wetness, the ingress protection can be

reduced and the product can be damaged.

Do not charge wet earbuds. Completely dry wet earbuds with a dry

cloth before charging them.

extreme cases, they may even present a risk of:
