HD Bluetooth protocol，LDAC or AAC, aptx, ldac，HWA.
CE can support sbc, and some USB Bluetooth adapter only 3$ and it can support aptx protocal, so ,CE can support it?
I’ve not heard of LHAC.
Do you mean LDAC?
LDAC come from sony,96khz/24bit, max 990kbps.
lhac come from huawei, 96khz/24bit, max 900kbps.
Googling LHAC reveals nothing for me.
Do you have a site link that specifically references it?
sory for some mistake. LHAC may be HWA.
