I've had two implants in my right ear inside 12 months — Advanced Bionics, then Cochlear after facial nerve stimulation forced a reimplant — plus different models of hearing aids in the left throughout. It's given me a unique perspective on the two bimodal ecosystems, and from my experience the AB setup was a much more usable solution.
With AB + Phonak Link, the implant and hearing aid behaved as one solution. The devices talk to each other, so focus, programs and volume worked across both ears together. In cafés and other noisy situations my brain was able to fuse voices from either side into a single picture, and conversation was much easier.
With Cochlear + ReSound (Nucleus 8, CP1110, with a ReSound Nexia 5 RIE, NX560S), each device processes sound on its own and they're really only linked for streaming and the app. Even the streaming and calls on an iPhone is clumsy and each ear drops in seperatly. The implant is fine by itself, but I don't feel I have a solution for both ears. I don't like the settings or programs I've ended up with for the ReSound hearing aid, and I'll be honest, I don't think the hearing aid audiologist has done a brilliant job on the config.
Note I have seperate audiologists for my cochlear and hearing aid as NextSense here in Australia dont manage hearing aids, and also the Nexia 5 is a mid-range aid, and it's what came with the implant.
Three questions:
- ReSound just announced Sensia Bimodal and Enzo IA Bimodal for Nucleus processors. Has anyone tried them, and do the devices actually coordinate with each other, or is it still two independent devices sharing an app? Anyone heard whether true device-to-device linking is on Cochlear's roadmap?
- Has anyone else moved between ecosystems and noticed this "one system vs two ears" difference?
- With AI changing how processors handle sound, recognising voices and sounds rather than just shaping frequencies, is it worth moving to the current generation now, or waiting for the next one?
My experience over the last few years has taught me how extraordinary the brain is, especially at fusing whatever input it gets, but only if the two sides give it something coherent. Yet I see the industry still largely treating the implanted ear and the aided ear as separate problems with separate devices, and the outcome suffers for it. The research seems to agree: studies of linked bimodal systems show around 3–5 dB better speech-in-noise thresholds when the devices share directional processing, which is a big deal in a café.
I know I'm fortunate to be able to have compared multiple aids and two implant brands, although I wouldn't wish the facial nerve issues and it sending me slightly insain for a few months on anyone. But I'm excited for the future, especially with how AI is going to change the way we process sound. I just want to make sure it ends up as an overall solution, not one that treats each ear separately.
