Research & evidence

  • Supported: App-specific study
  • Supported: Randomized app study
  1. Applies to the ReSound Assist remote-help service only: the hearing care professional must enable it, and it is offered in select markets. Basic hearing-aid control needs only compatible hearing aids.
  2. Only for ReSound Assist (remote help, new settings) and the Tinnitus Manager: the hearing care professional must enable these. Direct volume/program control works with paired compatible hearing aids.
  3. Evidence: Introduction > Intended purpose (p. 3).
  4. Required for ReSound Assist (requests, receiving new settings) and hearing-aid software updates; ReSound does not state that direct local control needs a connection.
  5. App data is held on the phone; GN cloud services store access attempts, crashes, erroneous usage and firmware downloads/updates. Cloud communication happens only with user consent and when hearing aids are paired. Evidence: Cybersecurity (pp. 12-13).
  6. Only during a ReSound Assist Live session with the hearing care professional (live audio/video call); ReSound Assist Live is documented for iOS and in selected countries. Evidence: Tinnitus management > Intended purpose (p. 8); ReSound Assist Live (p. 11).
  7. When sending a ReSound Assist request (optional personal message) or chatting during ReSound Assist Live; requires the service to be enabled by the hearing care professional and available in the country. Evidence: ReSound Assist Live > How to fill in your information / How to send your request (p. 10).
  8. By request to GN's Data Protection Officer under GN's general privacy policy; portability depends on applicable law and circumstances. No in-app export is documented. Evidence: 13. Your rights.
  9. GN states the system communicates with its cloud only if the user consents; cloud-dependent services such as ReSound Assist and remote updates need a network connection. Evidence: Cybersecurity (p. 13).
  10. Requires compatible hearing devices and a supported phone. Functions vary with model, firmware and professional configuration.
  11. Sound Enhancer speech focus requires a hearing-aid model and professional fitting that expose the control.
  12. Tinnitus Sound Generator must be supported and enabled by the hearing-care professional. Only where the hearing-care professional has enabled this feature.
  13. Compatible GN hearing aids and phone; adjustments depend on professional fitting. Remote services and updates require supported models and provider/market availability.
  14. Battery status is documented for compatible rechargeable hearing aids only.
  15. Requires compatible hearing devices and a supported phone. Functions vary with model, firmware and professional configuration. Location permissions and a previous connection may be required; last-known location is not live GPS in the hearing aid.
  16. Requires supported hearing aids, an enabled participating hearing-care provider, and service availability in the market.
  17. Requires Made-for-iPhone (MFi) ReSound hearing aids paired in iOS accessibility settings; otherwise a ReSound Phone Clip+ is needed. Streaming is handled by iOS, not by an in-app player.
  18. Direct Android streaming needs Android 10 or later, a phone model whose manufacturer implemented Android Streaming to Hearing Aids, supported hearing-aid firmware (e.g. LiNX Quattro 1.0.43+) and Smart 3D 1.5.0+, with pairing done through the app; otherwise use a Phone Clip+.
  19. Auracast-enabled ReSound Vivia, Enzo IA, Savi or Nexia; supported phone, hearing-aid firmware and app version are required. A local broadcast must be available.
  20. Models named in ReSound's Smart 3D FAQ; ReSound directs users to resound.com/compatibility for the current list, which also lists newer smartphone-compatible families (Sensia, Vivia, Enzo IA, Savi, Nexia, OMNIA).
  21. Remote support and remote fine-tuning (ReSound Assist) depend on the hearing-aid model, the professional enabling them and country availability; ReSound Assist Live is documented for iOS only. Evidence: Introduction > Intended purpose (p. 3).
  22. Direct streaming needs MFi hearing aids on iOS, or Android 10+ phones with Android Streaming to Hearing Aids plus supported firmware; a Phone Clip+ is the alternative.
