I've got AirPods and a Beats headset so they both support AAC and to my ear sound great. Keep in mind I went to a lot of concerts in my 20s without earplugs so my hearing isn't necessarily the greatest anymore. AFAIK Android's AAC quality isn't that great so aptX and LDAC are the only real high quality options for Android and headphones. It's a shame as a lot of streaming is actually AAC bitstreams and can be passed directly through to headphones with no intermediate lossy re-encode. Like I said though, to get Opus support in A2DP a BT SIG member would really have to be in love with it. Qualcomm and Sony have put forward aptX and LDAC respectively in order to get licensing money on decoders. Since no one is going to get Opus royalties there's not much incentive for anyone to push for its inclusion in A2DP.
