Got it in the middle of May 2019 I have used a bluetooth DAC from AFiio called Btr3 for over six months now. The reason I got it was because the experience of using a lightning to jack dongle while having my iPhone in a pocket was a miserable nightmare of disconnections all the time. And I did not want a pair with bluetooth built in because the options are limited and expensive. Also because if the bluetooth break, you have to replace the whole thing. The total price is about the same as the flagship headphones from Sony or Bose. But I think you can get much better headphones. And you can replace the bluetooth unit or the headphone unit independently. The experience is a little bit worse. But I think the whole package is better.
