Important safety instructions
To avoid damage to your hearing:
· Set a low volume setting before inserting the earphones!
· Do not use the earphones for long periods of time with a high
volume setting!
To avoid damage to your auditory canals and
eardrum:
· Place suitable pads on the earphones (S, M or L). Never insert
the earphones without pads!
· Always insert and remove the earphones from the auditory
canal slowly and carefully! Do not insert the earphones too
far into the ear!
· Always keep the earphones dry.
To prevent accidents:
Do not use the earphones in environments in which particular
attention must be paid (e.g. on roads or while carrying out ma-
nual work).
Note on sound quality
The sound quality of the earphones, incl. bass performance, de-
pends largely on correct positioning. To achieve the best possib-
le sound results, the accompanying ear pads or earphone covers
should therefore be used.
