Is there anything stopping us from using LE Audio right now?

The Sony Linkbuds S claim:

"These earbuds are ready for LE Audio, a next generation Bluetooth audio that enables ultra low latency - ideal for gaming."

The Intel AX211 card claims:

"On top of existing features, Bluetooth® 5.3 includes an Isochronous Channel feature, which lays the foundation for implementation of the next generation of Bluetooth® Audio – Low Energy Audio."

Intel's product description is less than explicit, but I'm guessing that means they support LE Audio.

If I were to buy both of these devices right now, is there anything stopping me from actually using LE Audio? Also has anyone heard if LE Audio will work on Windows 10?
