I will say however, the combination of this Anker adapter and my iPhone 6S on iOS 10 beta has the lowest Bluetooth latency I've ever experience. When pausing there is only a fraction of a second delay, not the getting-on-for 1 second delay I've seen in the past.

Still laggy enough to be annoying though.

I did try out the new Bluetooth version of the Bose noise cancelling headphones, the delay on those was over half a second, very annoying.

I realise this lag probably isn't even noticed by some people
