Translated from the original German article


For large auditoriums there are customised microphone concepts, for individual ears unique headphone are manufactured. The lot size of one becomes a core message at the company’s headquarters in Heilbronn. The maximum of individuality is almost invisible. On request the new DX 120 iE and DX 160 iE are supplied via a voucher for “earmoulds“. Instead of the standard ear tips the hearing aid acoustician will take a moulding of the inner ear. It does not hurt and it does not take long, but it will ensure a perfect fit and the highest sound gain to the eardrum.
