Yes plus LE Audio will be backwards compatible with some devices and is true wireless stereo broadcast, this is a game changer for sure, I wouldn’t bother with anything that is 4.2 now. LE Audio is expected to be up to 50% of the market in the next few years, for HAs/hearables it’ll be far more then that.
Phonak tried to get around the limitations of 4.2 by using the “master/slave” set up, too power hungry, dual streaming will minimise power consumption plus latency as well.
I’ve even heard that 5.2 could be “updated” to accept LE Audio as well, so I guess even more devices could be used.
