C.A.I. BC series | C.A.I. BC series AX

Unique system

With *C.A.I. BC 800 series and C.A.I. BC  800 AX series  bruckhoff hannover presented the  first bone conduction system, which can be worn with a simple ring earpiece and a flexible connection. 

Both devices are the simple and brilliant answer to the problems of people with conductive hearing loss or single side deafness (SSD). In case of single side deafness (SSD) the sound goes from the deaf side without surgery, wires or radio waves through the cranial bone into the normal hearing ear. The client does not receive internal noises from the instrument, the acoustic shadow effect is eliminated and the client gets all acoustic informations from the deaf side.


The C.A.I. is a self supporting system and requires no carrier such as glasses,  headbands or surgery for  fixing. It uses a conventional ring-ear piece for open fitting and is worn like a modern bluetooth device.
C.A.I. BC 800 and C.A.I. BC 800 AX series differ in, that in C.A.I.  BC 800 AX  series is used an external microphone for power improvement.

*C.A.I. is the abbreviation for Concha Anchored Instrument.
