The Jabra Enhance Pro 20 is the Nexia. It’s rebranded because for eg Resound doesn’t want Costco’s pricing model to undermine the perceived premium value of the Resound brand everywhere. But we know that the Resound fitting software sees a Jabra Enhance Pro 20 and announces it as a Nexia as it connects.
Edit: If you head over to the LE Audio thread in this Forum, you will be able to read a Jabra press release that specifically says that the Enhance Pro 20 does support LE Audio and Auracast.
