Nope, LDAC won't work on your iPhone with the Sony WF-1000XM6. Not just with these earbuds—it doesn't work with any Bluetooth audio device on iOS. This is an Apple limitation, not a Sony problem.
Let me explain what's actually going on here.
LDAC is Sony's fancy high-resolution Bluetooth codec. It can push audio at up to 990 kbps, which is like three times what normal Bluetooth codecs manage. Great for audiophiles who want the best wireless audio quality possible.
The problem? Apple has never supported LDAC on any of their devices. iPhones, iPads, Macs—they all max out at AAC, which is Apple's preferred codec. So when you connect the WF-1000XM6 to an iPhone, you're getting AAC whether you like it or not.
Here's the silver lining though: AAC actually sounds really good on Apple devices. Apple optimized it for their hardware, and honestly, most people can't tell the difference between AAC and LDAC in a blind test. If you're streaming from Spotify or Apple Music (which are already compressed), you're definitely not going to notice what you're missing.
LDAC really only matters if you're listening to actual high-resolution lossless files—which is a pretty niche use case. Most people just aren't doing that.
If having LDAC is a dealbreaker for you, you'd need to switch to Android. It works great there—some phones might need you to enable it in developer options, but most modern Androids support it right out of the box.
But for iPhone users? Don't stress about it. Your music will still sound excellent.
