Well, I use my qudelix 5k for that. It is not the same, but it has high audio quality, LDAC, and maybe the best portable EQ ever.Yea, something like Xelentos adapter or FiiO LC-BT1 but high end. Xelentos are outdated and FiiO is nothing special for.. so called - audiophiles
If you can find a short MMCX cable, it's done.
