I have Bluesound system comprising Powernod 2, Node 2i and Pulse flex 2i. They are non-grouped and thus act as solitary speakers. On all these systems I experience a terrible audio latency when connected by Bluetooth to an iMac. For Powernod 2 it is in the range of 350-400 ms. For Node 2i it is in the range of 300-350 ms. It is just the same audio latency if I uses my iPhone 12 as a Bluetooth audio source.
As you say there will always be a slight delay with Bluetooth. But what do you mean by "slight"? According to Bluetooth there can be an audio latency of 35 ms in the system. Most bluetooth speaker have an audio latency of about 50 ms but never more than 100 ms. So, what is Bluesound doing to provide a delay of up to 400 ms? This is not a delay. This is not even an echo. This is two separate occasions. One occasion when you see the lips moving on a TV or a computer. And one occasion when you hear the sound in the Bluesound system.
Such a delay is absolutely unacceptable. What is the purpose with the Bluetooth facility on Bluesound? What version of Bluetooth is used in Bluesound equipments? And finally - what are you going to do about it.
