If your talking about the Shure RMCE-BT1 adapter then its absolute garbage, just put it back in the box (or the bin). Only the RMCE-BT2 is decent from Shure. Mine just arrived and already done a comparison to the V30+ and compared single to balanced. Already its a keeper for me. Comparing via 3.5mm wired the M11 has more life, body, clarity, bass impact, space, seapration than the V30+ using either my own FLAC/DSD files or listening to Tidal Masters, even though the V30+ does the full hardware unfold. (V30+ does still sound excellent too). I need to do much more listening but even with the easy to drive SE846's I percieve better audio over balanced but even via 3.5mm its superb. Works flawlessly with my Sony BT remote and recognised both my 512GB Samsung EVO microSD's and the music I have on them. Now going to try with my Fiio BTR3 BT adapter over LDAC.
