The Baha System includes accessories that allow you to customise your sound processor to fit your personality.

DAI Accessories for your Baha Sound Processor

Europin Direct Audio Input (DAI)

Baha Europin

The DAI is a standard accessory connector, allowing you to connect a wide range of accessories such as FM receivers from leading manufacturers, or the Cochlear™ Baha® audio adapter to your sound processor.

To connect an approved accessory to the DAI, match the accessory connector with the sound processor's DAI connector and gently push the accessory connector into the DAI port.

Make sure you switch your sound processor to the DAI program.

Audio adapter

Baha Audio adapter

The Cochlear Baha audio adapter allows you to enjoy direct input sound from stereo systems, computers, MP3 players or any sound system with a sound output. This gives you an enhanced listening experience when enjoying music and films. Always use the Baha audio adapter to connect your sound processor to any electrical or battery-operated equipment. Available with a short or long cable.


Baha Telecoil

The Cochlear Baha telecoil gives you better hearing when using a phone or in buildings supplied with loop facilities, such as churches, theatres and airports. The telecoil sends the signal directly to your Baha.

FM receiver

Baha FM receiver

Using an FM receiver makes listening easier in noisy environments such as classrooms. FM receivers can be specific in terms of how they connect to your Baha sound processor. Consult a hearing care specialist to determine the FM receiver that is best for you.

Battery doors

Coloured battery doors

Baha coloured battery doors

You can easily change the battery doors on your sound processor. Match your mood and style with a battery door design of your choice. Select from a wide range of colours for both standard and tamper-proof battery doors. Children can also customise their sound processor further with a range of fun battery door stickers.

Tamper-proof battery doors

Baha Tamper proof doors

To prevent the user from accidentally opening the battery door and exposing the battery, an optional tamper-proof battery door is available. This is particularly useful for children. The tamper-proof battery door should only be locked and unlocked using the specially designed tool included in the tamper-proof battery door kit to avoid accidental damage to the door. Contact your hearing care professional for tamper-proof battery doors.

To use the tamper-proof battery door:

  1. Make sure the screw slot is positioned vertically.
  2. Attach the battery door and slide it to its closed position.
  3. Turn the screw a quarter-turn clockwise to lock the battery door in the horizontal position.
  4. To unlock the battery door, turn the screw a quarter-turn anti-clockwise to vertical. The battery door can now be removed.
