To be honest I doubt it. They would advertise it if it had IOS compatibility. It's not the norm. Maybe.It’s a USB sound card, and computers are not only desktop or laptop type. iPad is a computer too, so is an iPhone. If they have implemented properly an USB DAC doesn’t require a separate driver. I am hoping that it will work with an iPad.
Open Spotify and/or Apple Music then enter “88” in the search. See the options offered to me. Can you replicate that functionality on a dedicated streamer?
