I thought I saw it here.
EDIT Google turned up an article with thus quote. They may have been mistaken though.
At the time of this writing, Oticon is the only manufacturer with an LE Audio-equipped Bluetooth hearing aid on the market, the Oticon More.
I found the reference here that linked to a press release saying the More is ready for LE Audio.
In addition to superior audiological performance, Oticon More™ features state-of-the-art direct streaming from both iOS and compatible Android™ devices and is prepared for the next generation of connectivity based on the upcoming Bluetooth LE Audio standard.
