2 User instrucons
Compared to convenonal “on-ear” headphones, “in-ear” headphones are insert-
ed carefully into the auditory canal. In this way the auditory canal is closed from
the outside and thus, disrupve ambient noise is ltered eecvely.
Please rst verify that the ear pads are rmly seated on the headphones. On the
sound body or kink-protecon a label (L, R) indicates the respecve posion of
each headphone. Even though there is hardly any dierence detectable between
the two headphones from the outside, they may dier in the inner life (for exam-
ple by the angle of the installed speakers).
For this reason, it is recommended to insert the respecve headphone into the
correct posion (L- Le, R-Right). The connecon cable should ideally point down-
wards. Slide the headphone now carefully into the ear unl it sits comfortably
and stably. Every ear is dierent depending on the size, therefore please try the
dierent included ear pads, if the headphones with the plugged ear pads do not
yet sit stably and feel comfortable.
