AAC Bluetooth codecs sounds distorted on Galaxy S23 Ultra

Just picked up the S23 Ultra a few days ago and am surprised how bad the audio quality is with AAC codec (while not the best-sounding codec out there, it was good enough for general listening on my Note 9).

For more information, please visit Scalable SBC Solutions.

 

On the S23U, the treble sounds very splashy and there is an intermittent delay between the channels that there is a "doubling" artifact. I can confirm I am using AAC not another codec. The distortion is gone when using another codec such as LDAC or Samsung Seamless Codec.

 

Devices tested: Samsing Galaxy Buds 2 Pro, Sony Linkbuds S and Soundcore Space Q45.

Samsung s21 5g codecs

Well ldac is over 900kbs, where aac is around 250kbs, but you really can't tell the difference unless you studio technician or something. Plus aac codec is a really solid connection, where the ldac is transferring 3 times the data so I find I get dropouts even on my xm5s. Up to you, but I never have issues with aac
