Cochlear™ Baha® systems

Cochlear Baha 5 Family

The Baha System; a small, smart and powerful bone conduction hearing solution.

There are three primary components of the Baha Bone Conduction System: The external sound processor, an abutment or a magnetic connection which links the sound processor to the titanium implant, and the titanium implant that is implanted in the bone and osseointegrates in the bone behind the ear.

Baha Attract

  1. A sound processor detects sound and transforms it to vibrations.

  2. Sound Processor magnet transfers the vibrations from the sound processor through the skin.

  3. The Implant magnet receives the vibration and transmits it to the implant.

  4. The implant transfers sound vibrations to the cochlea.

Baha Connect

  1. A sound processor detects sound and transforms it to vibrations.

  2. DermaLock™ Abutment connects the sound processor to the implant.

  3. Implant transfers sound vibrations directly to the cochlea.


Baha Attract System

The Baha Attract System transmits sound vibrations to the inner ear through a magnetic connection between the sound processor magnet and a magnet attached to the implant under the skin. The benefit is that there is no skin penetrating abutment, providing a good aesthetic outcome with no need for daily skin care.






The Baha Sound Processor magnets are available in different strengths to suit individual patients and lifestyles. Skin thickness and other factors such as hair thickness and skin compression will impact required magnet strength. Choosing a sound processor magnet that provides firm retention while ensuring wearing comfort is important to ensure good hearing outcomes.

SoftWear™ Pad

The unique Baha SoftWear™ Pad used on the Sound Processor Magnets is designed for both comfort and reliable retention. Unlike a rigid plate, the memory foam adapts to the head and distributes pressure evenly over the entire surface. Minimized pressure and maximized contact with the skin are important for optimal outcomes with a magnetic bone conduction implant system.



Baha Connect System

The Baha Connect System transmits vibrations through an abutment which connects the sound processor to the implant. When using the DermaLock™ technology, the skin is left intact round the abutment. The major benefit is the efficient transmission of vibrations, providing maximum amplification.





BIA400 Abutment

The BIA400 abutment is specifically designed and FDA-cleared for soft tissue preservation. With a unique surface coating and a concave shape, DermaLock™ Technology delivers advanced stability in soft tissue. Compared with titanium, the hydroxyapatite surface coating of the DermaLock abutment promotes soft tissue integration by allowing more cell binding proteins to bind to the surface, orienting them in a way that makes it easier for cells to attach.1,2
