So far the worst thing about them is that certain songs do have some crackling sounds at least on LDAC, and there's literally nothing that I know of that can predict which songs would have this or not, but I'm not that bothered by it honestly, it's slightly annoying but it's not common enough to make me want to not use the earbuds.
Battery life on LDAC isn't amazing, but it's also not that much worse than my Galaxy Buds Pros on AAC for an example.
For me the fit is good, the L eartips and the preinstalled wingtips are fine, even if my right ear possibly would want the largest wingtip, but I can't bear them looking different from each other lol.
ANC is slightly better than OK, but it seems very inconsistent even when I keep it locked at "high", sometimes it blocks sounds that I wouldn't expect it to, and sometimes it lets through sounds that I thought for sure would be more diminished with the ANC.
