Adjusting the volume

High volume levels and long listening times
can permanently damage your hearing.
Because in-ear headphones are placed
directly in the ear canal, they can become
6–9 dB louder than conventional headphones, and this
increases the risk of hearing damage.
► Before inserting the earphones, set the volume to
minimum. Only increase the volume after inserting the
earphones.
► Do not use the in-ear headphones at high volume for
a long time. When listening and speaking normally
with in-ear headphones, your own voice should still be
perceptible.
► In case of tinnitus, reduce the volume. If necessary,
consult a doctor.
You can personalise your Bluetooth® headphones with
the beyerdynamic MIY app. The app's "Statistics" function
records the sound pressure your ears are exposed to
over time. However, it only refers to the sound pressure
generated through the headphones' speakers and not to
that from external sources of noise.

Reducing perception of ambient noise

In-ear headphones drastically reduce perception of
ambient noise. Using in-ear headphones in road traffic
can be potentially dangerous. The user's hearing must
not be impaired to the extent that it causes road safety
risks.
Blue BYRD
► Do not use the in-ear headphones within the action
area of potentially dangerous machines and tools.
► Avoid using in-ear headphones in situations where
hearing must not be impaired – particularly in
road traffic, when crossing a level crossing or on a
construction site.

Changed acoustic perception

For many people, wearing in-ear headphones takes some
getting used to because the acoustic perception of their
own voice and body as well as the inner ear sounds that
occur while walking is different from the "normal" situation
without in-ear headphones. However, this initially strange
sensation usually diminishes after wearing them for a
while.

Cleaning

Dirt on the eartips and the formation of a warm and
humid climate in the ear canal can cause an increased
level of germs, which can increase the risk of an ear canal
infection.
► Regularly clean the eartips.

Risk of swallowing

► Keep small parts, such as product, packaging and
accessories, away from children and pets. They
constitute a choking hazard if swallowed!

Using the batteries

Danger from heat, water and mechanical stress
Excessive heat, water and mechanical stress may
cause explosion, heat, fire, smoke or fumes. Injuries and

► Do not expose the battery (battery pack or integrated

► Do not open the housing or disassemble the battery.
► Do not use the battery if there is a risk it has come into
contact with water.
► Only use a USB 2.0/3.0-standard-compliant 5 V power
supply unit to charge the battery via the integrated
USB socket type C (current consumption is max. 0.5 A).
Storing the battery
► If the battery is not going to be used for an extended
