I own an LG V30 smartphone and a Fiio M6 media player both of which are capable of transmitting in Sony's LDAC codec.
What I don't own is a pair of bluetooth head or earphones. I own a variety of IEMs and a selection of headphones including Grado S80s, Philips SHP9500s, Sennheiser HD580s and Monoprice M560s.
I have a Radsone ES100 DAC/Headphone Amp which can handle LDAC. The Radsone is renowned for it's audio quality. I bought it when I had a smartphone without a headphone socket because as a USB DAC it's great. Despite that the sound via aptx-HD or LDAC still doesn't compare to a wired connection.
