but there is absolutely no need to worry about formats, like Apt-X and LDAC variations, because you are not going to hear any difference between SBC (A2DP) and the higher ones..
Heavily implies you did not try the other codecs and you are saying it doest matter as there is no difference....
Then there is clearly something wrong with your hardware or device you are using if you are not hearing any difference.There is a statement that BTR3's electronics is on a level that you cannot hear difference between the SBC and higher quality codecs
The difference should be night and day between SBC and LDAC.
Are you certain that the device and app you are using is actually using and outputting in the correct format each time you test, via looking at the HCI log?
What is the player device that u are using to play your music with? If is an Apple device, I believe those only do SBC/AAC. (I do not use Apple) .
My Pixel 3 (and my old 1st gen Pixel XL) u can toggele the BT codec used in the Dev settings and when u do so, the change is instant, but I do have to restart my player app, PowerAmpv3 and confirm that it is outputting in the correct format.
Also, what app are you using if you are using a smartphone....many apps do not support Hi-Res Output hardware output or the better BT codecs. I have noticed that some app, or stock player apps, they seem to force output to the lower codecs, even though the system and the BTR3 indicate the use of AptX or LDAC. However, when i read the BT HCI log output, it shows the use of SBC when that app plays music, and LDAC when I use PowerAmp (configured correctly)
