Settings for best sound
To achieve the best possible Bluetooth® sound with
your in-ear headphones, please observe the following
practical tips:
1. Set the volume to minimum on the in-ear headphones
and to maximum on the playback device.
2. Then adjust the volume only on the in-ear headphones,
not on the playback device.
This applies only to playback devices that do not
automatically synchronise the volume. On playback
devices that automatically synchronise the volume
(e.g. iPhone, iPad and various Android smartphones), the
headphone volume is always identical to the volume of
the playback device.
3. Deactivate any audio effects that may be present in
the software of the playback device.
