Yeah. I know, I was referring to other smartphones and that I don’t understand why they do not use aac as well. Aptx is marketed as something supercool and new but it isn’t. Usually only apple does that. Haha. By the way. Apple notebooks support aptx too. Just iOS doesn’t. https://www.macrumors.com/how-to/enable-aptx-aac-bluetooth-audio-codecs-macos/ Cheers.
