Happy mid week, music lovers,
Today I bring you an educational article, this time exploring the difference in sound quality between Bluetooth codecs, exploring which one sounds best, why, and also what can you do to have a more stable bluetooth signal and overall experience while using bluetooth headphones / IEMs / receivers

Good write-up, especially for people like me who know relatively little about Bluetooth codecs as a whole.
I do have a query about the section on AAC, though:
>The compression algorithm of psychoacoustics of AAC is similar to MP3, and it cuts out a lot of data, but which the algorithm assumes you won’t hear. For the average listener, the compression is easily audible, with a decent pair of headphones.
Is the Bluetooth AAC codec somehow different and less efficient than the lossy compression AAC codec? Because, if not, this is a serious case of "citation needed".
Apple's lossy AAC encoder is extremely good, and blind tests have shown that the vast majority of people cannot tell between high bitrate AAC and lossless (Source 1 | Source 2) and may even be challenging to discern at bitrates as low as 128kbps.
How were your assessments of which codec sounds better made, exactly? Did you conduct any controlled testing, or were you just basing them on the assumption that high bitrate = sounds better?
