Will the One work with my smartphone-connected hearing aids?

The short answer is, no. Your smart phone cannot be used as a streaming device for Thinklabs One.

Some new hearing aid systems, such as Oticon OPN and Resound LINX, are designed to work only via Bluetooth with Android and iOS smartphones. These systems have no streamer accessories. All of the accessories that exist for other hearing aids have been eliminated. Therefore, they do not work with anything other than a smartphone. There is no way to connect any other external sound source - Thinklabs One or any audio devices - to these models. Thus, the ONLY way to use the stethoscope with these models is with headphones worn over the hearing aids.
