Honestly, I've been having excellent experience with BT (and headphones) with modern devices.
For example, my Lenovo T14s (2023 AMD version running the latest kernel) connects to my (5.2 version of BT) headphones really well. Similarly, my android phone connects to the same headphones and whatever device sends data, that's what I hear.
Similarly, my Steam Deck connects to two of the headphones I'm using (Sennheiser and Apple Airpods) seamlessly.
