Yes, the WF-1000XM6 supports LDAC and is one of the best earbuds out there for high-resolution wireless audio.

LDAC is Sony's codec for transmitting high-quality audio over Bluetooth. It can push up to 24-bit/96kHz audio at 990kbps – about three times more data than regular Bluetooth. In practical terms, that means more detail, better dynamics, and audio quality that gets close to wired connections.

These earbuds are officially certified for Hi-Res Audio Wireless, so if you're streaming from Tidal, Amazon Music HD, or any other high-res source, you'll actually be able to hear the difference.

There's a catch though: LDAC only works on Android. If you have an iPhone, you're stuck with AAC. It's still decent quality, but you won't get the high-res benefits. This is an Apple limitation, not Sony's.

On the Android side, you enable LDAC through the Sony Sound Connect app by going into Sound settings and selecting "Priority on Sound Quality." Just know that using LDAC eats into battery life a bit, and in really crowded wireless environments, you might get some audio stutters. The app lets you switch to "Priority on Stable Connection" if that becomes an issue.

Sony also includes DSEE Extreme, which uses AI to upscale lower-quality audio in real-time. It won't make a 128kbps MP3 sound like a studio master, but it does help fill in some of what's lost in compression.

Bottom line: if you care about audio quality and you're on Android, these deliver.
