For those wondering, this is the Version 1 of the Zipp (original large).
There is also a version 2,
and a “mini” in both version 1 and 2.
So 4 total versions, and apparently there are large warehouses full of these because they keep coming back!
This is from a farily-high-end company so not the same as the usual crap $20 bluetooth speakers. However the company apparently went out of business, so limited changes of future support or software updates.
