Yeah, Google’s Pixels, latest Samsungs or Sonys are all safe bets. Still, 5.2-5.3 bluetooth phones been out there for some time, along with similarly specced hearing aids, don’t expect them all to be updated, [especially HAs] to be compatible.
Even having android 13 might be not enough as it’s just part of the requirements, there are other variables at play too. I have two A13 phones and they are not LE Audio compatible [and will never be most likely]. While my newer [A13] Xperia is.
