Bluetooth LE headphones issues

I have a pair of Bluetooth LE earbuds (Sony Inzone Buds). Recently, whenever I connect these to my Fairphone 6, I don’t get any audio, and apps that play audio come to a crawl. For instance, youtube suddenly takes ages to load videos, playback is extremely slow, and no audio plays. As soon as I disconnect the headphones, everything returns to normal.

This behaviour does not happen with headphones that use regular bluetooth connection. Only Bluetooth LE. Anyone else have similar problems?
