In isolation aptx-hd when operating in aptx-ll mode is low enough latency that it can be used for gaming, however it’s very rare that standard bluetooth headphones will be low enough latency, at the very least I haven’t personally tested any devices that fit the bill when operating in aptx-hd. Im sure some bluetooth headphones will be able to, but none that i’ve come across. LC3Plus might actually be able to change this. IMO running a bluetooth dac is much more likely to get there.
