Bluetooth HFP 1.9 includes support for LC3 codec for Super Wideband Speech (SWB) in Handsfree mode [1], with 32kbps bitrate. Quality is significantly better than SBC. ETSI has tested this extensively and came to the conclusion that LC3 is better than Opus in some common conditions [2] Quote: LC3 at 32 kbps (LC3 32) provides significantly better audio quality than Opus-CELT at 32 kbps and complexity level 0 (OPUS_v114_c0 and COPUS_v114_c0) So there IS a solution for higher quality, which is LC3-SWB. It's just that both devices need to support HFP 1.9 to make use of better codecs, which will take a while especially on the headset side.
