BT5 offers vast improvements in operating ranges, but aside from that, no upgrades in terms of audio.
Incorrect. The long distance transmission mode restricts actual data rates to between 100kbits/sec and 500kbits/sec. The speed quickly drops as you move away as the transmission method bolsters error correction and connection resliiance while data rate takes a back seat. It was designed for sensors and connected devices, ie all your house appliances.
Currently data rates for audio are like 360kbit for SBC, anywhere from 400-700kbit for AptX depending on the quality mode used, and LDAC can take upwards of 900Kbit. If we want to take advantage of something in the future it would be the double data rate, but you can't just tell older profiles to use higher data rates outside of the range of bluetooth 2.x . We would need a whole new profile, and the moment that happens we will probably utilize direct streaming properly and thus not needs higher bit rates. Currently the future looks like this, Android O will have LDAC support giving android a very high quality streaming codec (but for the mean time, only for sony headphones), and it looks like apple is hooking up their Beats headphones with a way to direct stream AAC music. Its...a start. On the one hand direct streaming AAC means no recompression of your music, and on the other hand LDAC throws a whole lot of bandwidth at recompressing ALL audio, movies, youtube, games. Also I believe LDAC is low latency.
