Technology is such an integral part of our lives, and it just keeps getting better, easier and more accessible. Cochlear is constantly innovating to improve your hearing solution for performance and usability.

Not sure which device you have? There are a couple places to look to find your serial number. If you have a Nucleus device, it will be located on the inside of the curved piece that goes on your ear. Kanso Sound Processors have a serial number printed underneath the battery cover on the backside of the sound processor. If you have a Baha Sound Processor, look on the backside of the processor, below the snap coupling. On older devices, the serial number is typically found in the battery compartment. Once you have located your serial number, you will be able to follow the guide below to determine which device you have.

  • Serial numbers starting with [101] - Nucleus® and Kanso® Sound Processors
  • Serial numbers starting with [301] - Baha® Sound Processor portfolio
  • Serial numbers starting with the letter [O] - Divino® and Cordelle® Sound Processor portfolio.
