How to Improve Headphone Audio Quality Using the LDAC Codec

 


If you want to get the best sound quality from your Bluetooth headphones, you’ll want to make sure you’re using the LDAC codec. LDAC allows you to stream high-resolution audio wirelessly — giving you clearer, richer, and more detailed sound compared to standard Bluetooth codecs like SBC or AAC.

In this guide, I’ll show you how to manually enable the LDAC codec on your headphones and your playback devices (like your smartphone or tablet) so you can enjoy that hi-res audio goodness right away.

What Is LDAC and Why It Matters

LDAC is a Bluetooth audio codec developed by Sony.
Unlike regular Bluetooth, which compresses audio heavily, LDAC can transmit up to 990 kbps — which means less compression and higher sound quality.

It’s especially noticeable when listening to lossless audio files or streaming services that support Hi-Res Audio. The difference? Cleaner vocals, more depth in instruments, and better overall clarity.

Step 1: Check If Your Devices Support LDAC

Before anything else, both your headphones and your source device (like your phone or tablet) must support LDAC.

For this tutorial, I’m using:

  • 🎧 Edifier W830NB Headphones

  • 📱 Google Pixel Phone

  • 💻 Lenovo Xiaoxin Pad Pro 2025

All of these devices are LDAC-compatible. You can usually find this information in your product’s spec sheet or Bluetooth settings.

Step 2: Enable LDAC on Your Headphones

Some headphones automatically use LDAC when it’s available, but others require you to manually enable it through a companion app.

For example, the Edifier W830NB uses the Edifier ConneX app (Android). Here’s how to enable LDAC on it:

  1. Download and install the Edifier ConneX app.

  2. Pair your headphones via Bluetooth.

  3. Open the app and go to Settings → HD Audio Codec.

  4. Choose the highest sampling rate available (usually 96kHz).

  5. Tap Save to apply the changes.

⚠️ Note: Your headphones may reset during this process. If they do, just unpair and re-pair them like you would when connecting a new device.

Step 3: Enable LDAC on Your Playback Device

Some Android phones (like the Google Pixel series) automatically switch to LDAC when supported headphones are connected.

However, on other devices (like the Lenovo Xiaoxin Pad Pro 2025), you may need to manually enable LDAC:

  1. Go to your Bluetooth Settings.

  2. Tap your connected headphones under Device Details.

  3. Look for the option to enable LDAC codec or High-Quality Audio and toggle it on.

💡 Pro Tip: You can also go into Developer Options → Bluetooth Audio Codec and manually select LDAC for even more control.

Step 4: Test Your Connection

Once you’ve enabled LDAC on both devices:

  • Play a high-resolution track from Spotify, Apple Music, or Tidal.

  • You should notice richer sound and improved clarity.

  • Some phones even show “LDAC” in Bluetooth settings or the status bar when it’s active.

Congrats — you’re now streaming in high-resolution audio!

Final Thoughts

Activating LDAC is a quick and effective way to boost your wireless sound quality. Even if you’re not an audiophile, you’ll notice the difference — especially with good headphones and quality audio sources.

So go ahead and try it out. You might be surprised at how much better your favorite songs sound when your Bluetooth connection isn’t holding them back.

Birthday Blues at the Border: My Solo Travel Nightmare at Philippine Immigration

August is my birthday month, and this year, I wanted to do something truly unforgettable: embark on my first-ever solo international trip! Weeks of planning went into my two-week adventure to Vietnam and Singapore. Flights booked, hotels secured – everything seemed to be going smoothly for my post-pandemic return to global exploration. I arrived at Manila airport a solid three hours before departure, a buffer I’d soon be thankful for. The immigration line wasn't too bad, maybe 20th in line. My turn came, and I hoped for a pleasant interaction, but it was clear from the officer’s demeanor that this wouldn’t be the case. Her tone and attitude screamed "power trip," and I had a sinking feeling this wouldn't end well. And it didn’t. I’m not a frequent traveler, and my last trip was way back in 2017 to Hong Kong. My passport was recently renewed, so no stamps to show. I completely understand the Bureau of Immigration (BI) needs to do their job, especially with the Philippi...

eSIM for Travel: Your Best Friend for Staying Connected Abroad

Hey there, fellow travelers! Let me tell you, an eSIM is an absolute game-changer for staying connected to the internet when you're exploring new countries. I'm actually writing this blog post right now from Ho Chi Minh City, Vietnam, and my eSIM has been a lifesaver! Just a couple of days ago, I flew in from Manila, Philippines. I had my trusty Pixel phone with a Globe physical SIM and a Smart eSIM. As soon as I landed at Tan Son Nhat International Airport, both my SIM cards automatically switched to roaming. But guess what? I hadn't purchased any roaming data, so I was completely cut off from the internet. I was relying solely on the airport's free Wi-Fi, which was pretty unreliable – limited coverage and super slow, probably because everyone else was trying to use it too! My eSIM to the Rescue! This is where my eSIM swooped in to save the day. Before my trip, I did my research to find an eSIM with unlimited data. Since I'm working remotely and my stay was for sev...
