That is unfortunate. It does look like they went out of business. I did own a Wren back in the day, and it was much better sounding than the HomePod. They probably did not have an Airplay2 speaker, but the Airplay1 was excellent.I'll have to take your word on the sound quality as I have never seen/heard one.
Is the company even still around, their website seems to be broken, and many places that sell them say discontinued or out of stock?
Are any of them Airplay 2 compatible? Everything I saw just mentions Airplay, which I assume means just the first generation technology.
The Airplay models I did see for sale in stock were the same price or higher than the Airpod.
The speakers themselves were very natural and did not sound artificial like Bose/HomePod.
