Sony YY2959 Appears on Bluetooth SIG (Update WH-G900N)

Another Sony headset has appeared on Bluetooth SIG, the YY2959. So what could this be? At this moment I have no idea, but it seems to only support up to Bluetooth 5.0, which could indicate a lower end model. But more on that later.

Sony YY2950 shows up on the FCC (update)

I decided to group all the information about the YY2950 into one post, rather than have it combined with the Walkman devices post.  The top photo shows the label and outline of the charging case,  confirming we are looking at a WF headset.
