LDAC is Sony’s own Bluetooth audio codec, and unlike the usual SBC or AAC you find on most wireless headphones, LDAC actually gives you a real shot at hearing your Hi‑Res tracks the way they were meant to sound. It can stream up to 32-bit/96 kHz audio at bitrates reaching 990 kbps — which is around three times more data than standard Bluetooth audio can handle through SBC.

When I first saw those numbers, I was skeptical. “Bluetooth and Hi‑Res audio?” I’d been burned before by big claims on wireless performance. But then I tried a pair of Sony WH‑1000XM4s connected to a phone with LDAC turned on, playing FLACs through USB Audio Player Pro, and it genuinely sounded fuller than the same tracks over AAC. There was more air between instruments, vocals had more texture, and overall it just felt more hi-fi.
It’s not lossless, technically speaking — we’ll get into that — but it gets very close, and for most ears in most environments, it’s hard to beat unless you’re wired.
How Does LDAC Work?
At its core, LDAC works by transmitting audio using more efficient compression and packet handling than what SBC or AAC typically allow. It offers three bitrate settings: 330 kbps, 660 kbps, and 990 kbps. Some phones and devices will automatically adjust between them depending on connection quality, while others let you manually select the bitrate through developer options.
I keep mine locked at 990 kbps on my Pixel 7 Pro. If the connection drops, it’s rare, and I’d rather have better sound quality than a more stable stream with lower fidelity. That said, when I tested LDAC on an older budget Android tablet, forcing the highest bitrate made the connection skip constantly — especially if I moved more than 5 metres away from the earbuds.
So LDAC is smart enough to adapt, but if your gear can handle it, you can force the top setting and enjoy some of the best Bluetooth audio currently available.
LDAC vs Other Bluetooth Codecs
Bluetooth codecs are a mess to compare because they each aim for slightly different goals. AAC is tuned for Apple devices, aptX Adaptive balances quality and stability, and SBC is just… there. It’s the default everyone has to include.
LDAC stands out by offering the highest available bitrate among mainstream codecs. It reaches 990 kbps, while aptX HD taps out at 576 kbps. That means, on paper, LDAC can carry more audio data and preserve more of the original detail.
In practice, I’ve found LDAC to consistently sound better than SBC and AAC, especially when listening to well‑recorded lossless tracks. Compared to aptX HD, it’s closer, but I still hear a difference in spatial detail — like the decay of a cymbal or background harmonies in acoustic tracks. It’s subtle, but it’s there.
The only issue is reliability. aptX Adaptive tends to be more stable when walking through crowded areas or switching rooms, while LDAC at max bitrate can cut out if your signal path isn’t clean.
Real-World Sound Quality
Here’s where things get more subjective, but also more exciting.
LDAC doesn’t just measure better — it actually sounds better. Reddit threads are full of users saying LDAC gives them “fuller audio” and “cleaner treble,” and I’d agree. I’ve used LDAC with both over-ear headphones and true wireless earbuds, and in both cases, music just felt more layered.
On my Sony WF‑1000XM5s, switching from AAC to LDAC made a noticeable difference on guitar-heavy tracks. Chords had more texture, and vocals were easier to separate from the mix. It wasn’t just louder or brighter — it was more refined.
SoundGuys did a blind comparison of codecs a while back, and LDAC consistently scored highest among listeners using premium headphones. It’s not always dramatic, but if you’re used to regular Bluetooth, the jump is easy to notice.
Even movies and games sound better. I tried playing Hellblade with LDAC active, and some of the whispered voices sounded sharper, clearer, and a bit more unnerving. That subtle clarity makes a real difference in immersive content.
Pros and Cons of Using LDAC
Pros
The biggest strength of LDAC is the audio quality. It supports up to 24-bit/96 kHz playback, and when set to 990 kbps, it carries almost three times the data of a standard SBC connection. That translates to better detail retrieval, wider soundstage, and less compression artifacting.
I’ve tested it across different devices — Sony XM4s, the newer Creative Zen Hybrid Pro, and a pair of FiiO wireless IEMs — and every time LDAC sounded more “open” than the same gear running AAC or SBC. On jazz tracks, the room reverb came through more clearly, and on electronic music, the synths had more texture.
Another thing I appreciate: it’s built into Android. Since Android 8.0, LDAC is natively supported, so you don’t need any special app or modded firmware to use it — just a phone and headphones that support it.
Cons
LDAC isn’t perfect. The first issue I ran into was stability. At the maximum bitrate, it can struggle with signal drops — especially if you’re moving around a lot or using it in a crowded RF environment. In a packed gym, I had to drop it down to 660 kbps to avoid cutouts.
Battery life also takes a small hit. It’s not a huge drain, but when I used LDAC at 990 kbps all day with my WF‑1000XM5s, I lost about 30–40 minutes of battery compared to AAC.
And then there’s compatibility. Apple devices don’t support LDAC at all. iPhones use AAC, and there’s no native way to change that. So if you’re in the Apple ecosystem, LDAC isn’t even an option. Even on Android, some budget phones might support it in theory but don’t give access to bitrate settings, which limits the experience.
LDAC Compatibility and Requirements
You’ll find LDAC support in most modern Sony headphones, including the WH‑1000XM3, XM4, XM5, WF‑1000XM4/5, and LinkBuds S. Many Android phones — especially from Sony, Google, Samsung, and OnePlus — also include LDAC in their Bluetooth stack.
To use it properly, you need both a source and receiver that support LDAC. If one side doesn’t, it defaults to something else, usually SBC or AAC.
There’s also a setting buried in Android’s developer options that lets you manually adjust the bitrate. I always go in and lock mine to 990 kbps. On the Pixel, it’s just:
Settings → About Phone → Tap Build Number 7 times → Developer Options → Bluetooth Audio Codec → LDAC → Bitrate: 990 kbps
It takes two minutes, and it makes a noticeable difference.
LDAC also works with select DAPs (digital audio players) and some dongles like the FiiO BTR5 or Shanling UP5. Not all true wireless earbuds support LDAC, so always check before buying — some brands advertise “Hi‑Res” but don’t include LDAC support at all.
Is LDAC Worth It for Gaming?
It depends on how you game.
If you play single-player titles or immersive third-person games, LDAC can add a lot to the experience. The wider soundstage, the cleaner highs — they help place environmental sounds in a way that feels more natural. When I used it for Spider-Man: Miles Morales on PS Remote Play, city ambience and voice lines popped more.
But for competitive gaming? Not ideal. LDAC has slightly higher latency than aptX Low Latency or wired connections. If you’re playing something like Valorant or COD Mobile and rely on pinpoint timing for footstep detection, LDAC might be a step behind.
I tested it with Game Mode off and on, and while it was fine for casual matches in Fortnite or Apex, there was a small but noticeable lag in fast-action sequences. For me, it’s not a deal-breaker, but if you’re ultra-competitive, aptX LL or a wired headset is still the better bet.
How to Enable and Optimize LDAC
If your phone runs Android 8.0 or later and your headphones support LDAC, enabling it is simple.
- Pair your headphones as usual via Bluetooth.
- Go to Android Settings → Developer Options.
- Find Bluetooth Audio Codec, select LDAC.
- Then set the LDAC audio quality to 990 kbps (Best Effort).
If the Developer Options menu isn’t visible:
- Go to Settings → About Phone.
- Tap Build Number seven times until you see a message saying Developer Mode is enabled.
Some devices default to “adaptive” bitrate for better stability, which is fine — but if you want the best quality, it’s worth locking it to the highest setting.
Also, use a proper media player. Apps like USB Audio Player Pro or Poweramp have better Hi‑Res support than Spotify or YouTube, which compress the source audio anyway.
Final Take: Should You Use LDAC?
If you care about sound quality and have a phone and headphones that support LDAC, there’s no real reason not to use it.
It delivers noticeably better clarity and depth than the usual Bluetooth codecs, and while it’s not perfect — especially in terms of latency and stability — it’s about as close to wired Hi‑Res sound as you’ll get over Bluetooth.
For Android users, LDAC is one of those features that makes a bigger difference than you’d expect. It won’t make bad recordings sound amazing, but if you already listen to FLACs or high-bitrate files, you’ll notice the improvement.
For gamers, it’s more of a mixed bag. Great for immersion, less great for competitive twitch shooters.
Overall, LDAC is worth enabling — just make sure you’ve got the right setup, and spend a few minutes tweaking the bitrate settings. The results speak for themselves.
FAQs About LDAC
Is LDAC truly lossless?
No. LDAC is lossy, but it’s very high-bitrate lossy. At 990 kbps, it preserves much more of the original signal than SBC or AAC. You won’t get bit-perfect audio like you would over USB, but it’s close enough for most listeners.
Can I use LDAC with iPhones?
Unfortunately not. iOS doesn’t support LDAC. If you’re on iPhone, your best Bluetooth option is AAC.
Does LDAC use more battery?
Slightly. Due to the higher bitrate, it consumes more power — both on the phone and on the headphones — but not by much. I usually lose about 5–10% faster battery drain compared to AAC on the same gear.
What happens if my connection is weak?
LDAC will auto-adjust to 660 kbps or 330 kbps to keep the stream stable. Some players let you override this and force 990 kbps — but expect skips if the Bluetooth signal isn’t solid.
Is LDAC better than aptX HD or Adaptive?
In most cases, yes. LDAC carries more data and sounds cleaner. But aptX Adaptive tends to be more stable and has lower latency. For pure music listening, I’d pick LDAC. For gaming or inconsistent environments, aptX might win.
