Why Does LDAC Keep Stuttering? How to Fix Unstable Bluetooth Audio
LDAC keeps stuttering is a problem that some Android users may experience, especially when using LDAC at higher bitrates such as 660 or 990 kbps. You may notice the music cutting out, skipping, or briefly dropping audio even though the headphones appear to be connected normally.
Many users immediately assume that their headphones are defective or that Bluetooth is malfunctioning. However, the problem can be caused by several factors, including Bluetooth bandwidth, wireless interference, distance between devices, obstacles, and LDAC settings.
The good news is that this does not necessarily mean LDAC is unreliable or that you need to replace your headphones. In many situations, adjusting the LDAC settings and improving the Bluetooth environment can significantly improve stability.
Why Can LDAC Stutter More at Higher Bitrates?
The key factor is the amount of data being transmitted over Bluetooth.
LDAC can operate at higher transmission bitrates than many traditional Bluetooth audio codecs. This allows more audio data to be transmitted, but it can also make the connection more sensitive to challenging wireless conditions.
Think of Bluetooth as a road:
- Lower bitrate = less data traffic and an easier connection.
- Higher bitrate = more data needs to be transmitted.
- Wireless interference = additional obstacles affecting the connection.
When the wireless environment becomes difficult, using LDAC at a high bitrate may result in audio stuttering, interruptions, or temporary dropouts.
This is why the highest available LDAC bitrate is not always the best setting for every situation.
Why Does LDAC Keep Stuttering?
1. The LDAC Bitrate May Be Too High for Your Environment
This is one of the first things you should check.
LDAC can operate at different bitrate levels, commonly around 330, 660, and 990 kbps. Higher settings provide more bandwidth for audio transmission, but they may require a cleaner and more stable wireless environment.
Therefore, if LDAC works poorly at 990 kbps, it does not necessarily mean that 990 kbps is a bad feature or that your headphones are defective.
Try lowering the setting to 660 kbps. If the connection becomes stable, you have identified an important factor affecting the problem.
In some environments, 660 kbps can provide a better balance between sound quality and connection stability.
2. Wireless Interference Can Affect LDAC Stability
Bluetooth operates in a radio-frequency environment where other wireless devices may also be active.
Depending on your location, nearby Wi-Fi networks, Bluetooth devices, smartphones, and other wireless equipment can contribute to a more challenging RF environment.
You may notice LDAC stuttering more frequently in places such as:
- Train stations
- Shopping malls
- Airports
- Crowded cafés
- Busy offices
- Public areas with many wireless devices
If LDAC works perfectly at home but starts cutting out in crowded public areas, the wireless environment may be an important part of the problem.
3. Your Smartphone and Headphones Are Too Far Apart
Bluetooth range is not determined by distance alone.
Walls, furniture, clothing, bags, and even the position of your body can affect wireless performance.
For example, if your smartphone is inside a pocket on one side of your body while one earbud is positioned on the opposite side, the signal path may be less favorable.
Try placing your smartphone closer to the headphones and play the same track again.
If the stuttering disappears, distance or physical obstacles may have contributed to the problem.
4. Multiple Bluetooth Devices Are Connected
Your smartphone may be connected to several Bluetooth devices at the same time, such as a smartwatch, keyboard, mouse, car system, or other accessories.
Although modern smartphones are designed to manage multiple Bluetooth connections, additional wireless activity can make troubleshooting more complicated.
Try disconnecting Bluetooth devices that you are not currently using and test LDAC again.
5. Headphone Firmware or Smartphone Software May Be the Problem
Bluetooth audio performance depends on both hardware and software.
Headphone firmware, Android system software, Bluetooth drivers, and manufacturer-specific audio implementations can all affect how Bluetooth audio behaves.
If LDAC suddenly starts stuttering after a software change or has behaved strangely since a recent update, check for:
- Android system updates
- Headphone firmware updates
- Manufacturer headphone apps
- Bluetooth settings
Keeping both the smartphone and headphones updated can help eliminate software-related issues.
How to Fix LDAC Stuttering
Method 1: Lower LDAC from 990 kbps to 660 kbps
If you are currently using 990 kbps and experiencing audio interruptions, try switching to 660 kbps.
This is one of the most practical solutions because it allows you to continue using LDAC while reducing the amount of data that needs to be transmitted over the wireless connection.
For many users, 660 kbps can be a useful middle ground between high audio quality and connection stability.
Method 2: Try 330 kbps if 660 kbps Still Stutters
If the connection remains unstable at 660 kbps, try reducing it further to 330 kbps.
Although the transmission bitrate is lower, the reduced bandwidth requirement can make the Bluetooth connection more tolerant of difficult wireless conditions.
If the stuttering disappears immediately after lowering the bitrate, this is a strong indication that the problem may be related to wireless conditions rather than defective headphones.
Method 3: Keep Your Smartphone Closer to Your Headphones
For troubleshooting, place your smartphone close to the headphones.
Play the same track using the same LDAC setting and observe whether the audio remains stable.
If the connection becomes stable, gradually increase the distance to determine how the connection behaves under different conditions.
Method 4: Avoid Areas with Heavy Wireless Interference
If LDAC only stutters in certain locations, you may not need to permanently lower the bitrate.
For example, you could use a higher LDAC bitrate when listening at home and switch to a lower setting when travelling through crowded areas.
This gives you a more flexible setup instead of forcing one LDAC setting for every environment.
Method 5: Reconnect Bluetooth
If the Bluetooth connection appears to be behaving abnormally, try reconnecting it.
- Pause the music.
- Turn Bluetooth off.
- Wait a few seconds.
- Turn Bluetooth back on.
- Reconnect your headphones.
- Check the active Bluetooth codec again.
If the problem continues, you can also try removing the headphones from your Bluetooth device list and pairing them again.
LDAC 330 vs 660 vs 990 kbps: Which Should You Choose?
| LDAC Mode | Main Advantage | Connection Stability | Recommended Use |
|---|---|---|---|
| 330 kbps | Lower bandwidth requirement | Generally more tolerant of challenging environments | Traveling / crowded areas |
| 660 kbps | Good balance between quality and stability | Good | Everyday music streaming |
| 990 kbps | Highest LDAC transmission bitrate | More dependent on a favorable wireless environment | High-quality listening in stable environments |
Remember: 990 kbps does not automatically mean better sound in every situation.
If 990 kbps causes frequent interruptions while 660 kbps plays continuously, 660 kbps may actually provide the better real-world listening experience.

What If LDAC Only Stutters with Spotify or YouTube Music?
If the problem happens only with one music app, do not immediately assume that LDAC itself is the problem.
Try playing music from another service or from a local audio file stored on your smartphone.
For example, test:
- Spotify
- Apple Music
- YouTube Music
- Local music files
If every source stutters, the problem may be related to the Bluetooth connection, smartphone, or headphones.
However, if only one application causes the problem, check that app's settings, streaming quality, battery restrictions, and background behavior.
Does Hi-Res Music Cause LDAC to Stutter?
Not necessarily.
Music source quality and LDAC transmission bitrate are two different parts of the audio chain.
A Hi-Res source does not automatically cause Bluetooth stuttering, and a lower-quality source does not guarantee a perfectly stable connection.
Audio stuttering is primarily related to the stability and capacity of the wireless transmission under the current conditions.
Therefore, using LDAC at 990 kbps with a high-quality music source may still result in interruptions if the Bluetooth environment is unstable.
Do You Need to Use LDAC 990 kbps All the Time?
No.
This is one of the most common misunderstandings about LDAC.
Choosing the highest available bitrate does not mean that it is always the optimal setting.
If you are listening at home with a stable Bluetooth connection, 990 kbps may be a reasonable choice.
However, if you are travelling, using public transportation, or surrounded by many wireless devices, lowering the bitrate may provide a more stable listening experience.
Recommended LDAC Settings for Different Situations
| Situation | Recommended Setting |
|---|---|
| Listening at home | 660 or 990 kbps if the connection is stable |
| Traveling | 330 or 660 kbps |
| Shopping malls / train stations | 330 or 660 kbps |
| Experiencing audio stuttering | Lower the bitrate by one level |
| Maximum connection stability | 330 kbps |
| High-quality listening in a stable environment | 990 kbps |
Does LDAC Stuttering Mean You Need New Headphones?
Not necessarily.
Before buying a new pair of headphones, try adjusting the LDAC bitrate first.
If changing from 990 kbps to 660 kbps eliminates the stuttering, the problem may be related to wireless conditions or connection stability rather than a hardware defect.
If the headphones continue to disconnect or stutter even at 330 kbps, test the headphones with another compatible smartphone if possible.
This can help determine whether the issue is coming from the headphones or the original smartphone.
How to Check Whether Android Is Actually Using LDAC
On compatible Android devices, you can check the active Bluetooth audio codec through Developer Options.
After connecting your headphones, look for the Bluetooth Audio Codec setting.
If Android is using another codec instead of LDAC, changing an LDAC-related setting may not have the effect you expect.
The exact menu names and locations can vary depending on the smartphone manufacturer and Android version.

Conclusion: How Do You Fix LDAC Stuttering?
If LDAC keeps stuttering, do not immediately assume that your headphones are defective. The cause may be related to a high bitrate, wireless interference, device distance, multiple Bluetooth connections, or software and firmware issues.
Try these solutions in order:
- Lower LDAC from 990 to 660 kbps.
- If the problem continues, try 660 to 330 kbps.
- Move your smartphone closer to the headphones.
- Avoid areas with heavy wireless interference.
- Disconnect Bluetooth devices that you are not using.
- Update your smartphone and headphone firmware.
- Remove and pair the headphones again if necessary.
The most important point is that LDAC 990 kbps is not automatically the best setting for every situation.
If 660 kbps gives you stable, uninterrupted playback, it may be a better choice than 990 kbps for everyday listening.
Ultimately, good Bluetooth audio is not only about using the highest bitrateit is also about maintaining a stable connection and uninterrupted playback.
