This makes it incredibly versatile for a wide range of applications.

A: Yes. Because it supports a full suite of codecs including SBC, AAC, aptX, aptX-AD, and LC3, it is compatible with the vast majority of Bluetooth headphones, earbuds, and speakers on the market — not just LE Audio-enabled devices.
