Comment on Why is Bluetooth sound quality bad on my MacComments−lxgr2yNotably, while SBC is ubiquitous and sounds quite ok for A2DP/"music mode", there's are two possible codecs for HFP:- Uncompressed 8-bit, 8-kHz PCM: Potato quality, equivalent to a legacy digital phone line)- mSBC: A latency optimized version of SBC, offering at least 16 kHz thanks to some level of compression. (Sweet potato quality?)Make sure that your headset supports at least the latter to make HFP mode slightly less unbearable!−dgrcodeOP2yI'm using mSBC, but the quality difference compared with AAC when not using the microphone is wild.

Make sure that your headset supports at least the latter to make HFP mode slightly less unbearable!
