Baha® 4 Connect System

The Baha® 4 Connect System* has an abutment that offers a direct connection between the Baha sound processor and the implant for maximised hearing performance. The system includes a range of innovative and intuitive new features, including wireless technology, to offer you more possibilities for a lifetime of better hearing.


Unmatched implant performance

The Baha 4 Connect System is built around the feature-packed Baha 4 Sound Processor with wireless technology. The DermaLock™ Abutment with proven performance1 provides a direct connection between the implant and the sound processors and shortens time in surgery with improved outcomes.

It has been approved for shorter time to fitting compared with conventional solutions. You can enjoy better hearing sooner thanks to the unique Baha implant technology that lets you wear your sound processor as soon as two weeks after surgery.

How does it work?

Baha 4 Sound Processor features

Smarter hearing

At the heart of the Baha 4 Sound Processor lies the powerful new Ardium™ platform. It is three times faster, and has eight times the on-board memory compared with previous generations.

And we don’t let the power go to waste. Our intelligent classifier (Baha PureSound™ iQ) improves your hearing and your listening experience – wherever you are and whenever you need it.

True wireless freedom

For the first time, our bone conduction hearing system includes wireless technology with sound streamed directly to your sound processor.

The range of easy to use accessories let you hear better in challenging situations, while providing you with a robust connection to some of your favourite electronic devices (such as your mobile phone, computer and TV).

A strong foundation

The latest Baha Implant serves as the foundation for both Baha 4 Systems and is more stable than previous Baha implants. It takes advantage of the latest TiOblast™ surface technology, which benefits are documented in numerous clinical studies some of which have now run for over 3 years.

The stability of the implant positively affects its predictability and reliability. With higher predictability, the Baha Implant is the superior choice in bone conduction.
