I think the issue is well known in the industry. Traditional bluetooth/wifi headphones could get away with it because L and R speakers are wired even if there was no wire for the audio source. There is a standard[0] being worked on but AFAIK currently there is no wireless version. Bluetooth is really a joke for audio. The reason why it is used on so many speakers today it's because most(if not all) of them don't work in a multi-channel configurations(i.e. stereo pairs) so they just allocate a big buffer to make up for the poor connectivity. The issue in multi-channel configurations is that you need to re-sync all the speakers constantly(i.e. every 0.5s) so the big buffer approach is not good enough anymore. Most of the bluetooth systems also convert the audio source to a more lossy format to reduce the bandwidth requirements. Shortly said bluetooth is not the future of wireless audio. At least not as it is today. Today it's rubbish compared with wired versions. Apple just packed a flawed technology in a nice package.
