- Adults aged 18 or older
- People who have had a Cochlear Baha BI300 implant fitted together with a Cochlear Baha BA300 Abutment (known as the Baha Connect System)
- People who have a type of hearing loss — either mixed or conductive — in the ear where the Baha Connect System is fitted
- People whose bone conduction hearing test results in the implanted ear fall within a specific range (a PTA4 score of 55 dB HL or better — confirm with trial site if unsure what this means for a specific case)
- People who have been using the Baha Connect System for at least 6 months
- People whom the trial doctor has assessed as being unhappy with their current Baha Connect System due to medical problems, such as repeated skin reactions around the device, and who are considered likely to benefit from switching to an Osia System
- People who are fluent speakers in the language being used to test hearing and speech understanding during the trial
- People who are willing and able to sign a written consent form
- People who have medical records going back to when their Baha Connect System was implanted, and where the trial site is authorised to review those records
Who may not be able to join:
- People who are deaf in one ear but have normal or near-normal hearing in the other ear (specifically, an air conduction PTA4 score of 20 dB HL or better in the good ear — confirm with trial site)
- People who have an active, severe skin infection at the implant site at the time of their initial screening appointment
- People who, in the trial doctor's judgement, are unable or unwilling to follow the requirements of the trial
- People who work at the trial site and are directly involved in running this study, or their immediate family members (spouse, parent, child, or sibling)

- People who are currently taking part in another clinical trial involving an experimental drug or device, or who have done so in the past 30 days (unless the other trial is also run by Cochlear and the trial doctor or Cochlear determines there is no conflict)
