Luckily I bought both of these items from Aliexpress on sale for cheap or I'd be a little upset. The buds support LHDC and LHDC LL if in game mode. Connecting them was a tad tricky but I managed to get them paired. I wasn't able to achieve 192/24, best was 96/24 and switching to LL it was 48/24 even with Android SRC bypassed by UAPP. Perhaps user error but I'll try on my tablet instead of my DAP tonight.
Despite all the connection hassles the real disappointment was the Ceramic Ultra itself. It's probably the worst tuned buds I've tried and I had to eq the heck out of them to get rid of the tinny sound. Guess I'll be sticking with my Soundpeats H3 and good ole LDAC or APTX Adaptive until I can find better buds for the LHDC One dongle. Keeping in mind YMMV with the buds but to me they are sub par.
Edit: After changing the tips, eqed and putting several hours in on these they have mellowed out quite a bit and sound much better. Not bad at all for the low price. Guess I jumped the gun but out of the box they were not ideal. Must have patience with these buds.
