SBC codec, that is default and mandatory suck ass. It was chosen because they didn't want to pay the patent licensing fees of something better.
SBC was made for voice and is acceptable for that. Better codecs like AptX and AAC exists in many devices now, but because of incompabilites SBC is often negotiated anyway.
- GaryNumanVevo 7y agoMy BT headphones will generally use AptX when connected to my macbook, but when it tries to use audio from them, i.e. bluejeans randomly opens, it'll drop to SBC and immediately all my music sounds like junk.
- KozmoNau7 7y agoSBC can be quite good, but only if your devices can agree on a high enough bit rate. BlueZ on Linux can be prodded into negotiating a bit rate that's higher than default, and then it sounds pretty good, certainly good enough for BT speakers. SBC is not a bad codec. It is a low complexity codec (sort of similar to MP2) optimized for low power consumption and quick encoding/decoding, and I think it's been unfairly maligned, due to devices that are way too stingy with bit rates.
- bni 7y agook, you are probably correct. BT music from my iPhone to my car stereo sounds bad. There I cant verify what codec or bitrate is used, but clearly is a difference when comparing to a music file played from an SD card reader on the dashboard. I also have a pair of Sony bluetooth headphones that I use with my MacBook, here the sound is awful, until I use a BT utility to choose aptX instead, that they also supports, but SBC is default selected anyway.
