When will direct audio streaming from Android be available for the LiNX Quattro hearing aids?

Without having a crystal ball, there is no way to calculate a release date for "direct to Android" connectivity to the Quattro.  Trust me, we all keep asking!   We do know that it will be possible sometime in the future as Google is working with Resound to make this happen.

The current Resound Linx Quattro Hearing aids require the Phone Clip Plus streamer to stream from an Android device. The Phonak Audeo B Direct will stream (phone calls only) from an Android to only one hearing aid at a time. There are several hearing aids that will stream any audio signal to both hearing aids from an iPhone.

Currently, it is slated for 2019 but no firm date has been set yet.

The first phone thought to have the capability is the Google Pixel 3 with other phones to follow later.

Insider news says that Resound is working directly with Google on developing Android streaming capabilities (Resound partnered with Apple to do this before the low power bluetooth chip was released). The news I have read also mentioned that Resound will be the first hearing aid company to have a product that allows streaming from an Android device. This hints at an arrangement between Resound and Google, which is certainly not surprising.

The real answer to your question, though, is unknown. I have not seen a release date or even a confirmation that direct audio streaming will be in the next major Android release, even though that seems to be the general assumption at this point. When that will be is unkown. Android 9.0 (codenamed "Pie") is in release right now, so the next major release will likely be a ways in the future.

Since Android doesn't have a uniform operating system, and each brand of phone has its own capabilities, streaming to all Android phones is nearly impossible.  Unitron has a very limited stream to all Androids, but only one ear and only phone calls.  Due to the very limited ability of stanard Bluetooth, it can only go to one device so therefore one aid.  

Hearing Aid Manufacturers are working with a select few Android Phone Manufacturers to resolve the issues of direct to phone streaming.  So eventually there will be some, but only limited to certain models and brands.  My feeling is that it will happen in the next couple of years. 

I was told that it is in the works and it is up to Android when it will be released.  It will only be for the Quattro products from my limited understanding.  I expect that there will be a firmware update that will allow it to happen.  No specific date has been announced.
