As promised, here's a video with more info on the Vista Pro. Sadly I don't have much in the way of concrete answers on how this got into my hands or what my model actually is, whether it's a limited release or a prototype or what, but I wanted to at least show off the device and talk about it a little.
Bought these off a local seller. Not the eBay listing that was posted a couple days ago. Will make another post later with more details on it, but they present like a clone of the Logitech Zone True Wireless (though I don’t own those so I’m probably wouldn’t pick up on smaller differences) and sound great. They are not recognized by the Jaybird app or the Logitech Tune app
I just came across them on eBay. I’m looking online but there’s no record of a vista pro ever being available.
