- Audio Delay / Lag - Visual Not Synced with Audio, Echo with TV Speaker
Audio latency is, essentially, the time it takes for audio data to move from your audio source to your headphones. Wired headphones produce an imperceptible amount of lag—about 5-10ms worth. Within this 5-10ms window, your phone or computer processes the digital audio data, converts said data to an analog audio signal, and then streams the signal through your headphones or speakers.
Bluetooth devices spend a lot more time to do this “processing”. The source device compresses the data and wirelessly transmits it. Then the headphones or speakers receive the data and decompresses it.
The wireless communication program is called a “Codec”. It acts like a specific language that the sender and the receiver agree to communicate with. Different codecs lead to different audio delay times.
Bluetooth Audio Codec
Audio delay
aptX™ HD
≥ 250ms
aptX™ Low Latency
~ 40ms
aptX™
~ 70ms
FastStream
~ 40ms
SBC (Sub Band Codec)
~ 220ms
To benefit from the lowest amount of audio delay, BOTH the sender and the receiver must support either the aptX Low Latency or the Fast Stream Codec. If only one side supports aptX Low Latency but the other side does not, the streaming will use the next available codec supported by both devices, such as SBC or aptX. You will find that your Bluetooth audio and TV speaker audio are not in sync.
How do you confirm whether your Bluetooth headphones support the aptX Low Latency or FastStream codec? Simply check its specifications in its product listing or manual. Apple Headphones and nearly all true wireless earbuds do not support aptX Low Latency. Some headphones claim that they do, unless they are a reputable brand, you still need to double check from Certified aptX Low Latency device list from www.aptx.com.
There is another factor that you need to keep in mind regarding audio delay, which is Codec priority. Many Bluetooth devices have a Codec "priority" list, meaning that it prioritizes using some Codecs over others when connecting to other devices. For example, the DG80 Dongle's Codec priority goes like this: 1.FastStream, 2.aptX low latency, 3.aptX, 4.SBC. When connecting with other devices, the dongle will go through these codecs one by one until it finds one that is supported by the device it's connecting to.
Where this gets tricky is if you are connecting multiple devices to each other. Bluetooth devices will use the lowest common denominator supported by all devices, not necessarily the fastest codec. This can result to a slower codec being used, even though your headphones support a faster codec. Read more here.
If you suspect that this is an issue, a fix is to factory reset / clear the pairing history of the devices experiencing audio delay. This may fix the issue.
What if my headphone is not low latency supported? You have the following options:
1. Change to a Low Latency supported headphone;
2. Get a headphone / transmitter Set. We have plenty of options HERE.
3. Live with the slight lip sync delay.

Back to Top - How to get My Avantree TV Headphones / Transmitters work well with my Samsung Smart TV?
If you're using one of the latest Samsung Smart TVs, you could encounter an issue when using Bluetooth Transmitters or Headphones. The issue is due to the fact that Samsung Smart TVs tend to pair with any Bluetooth devices it can find unless you manually deny the connection.
This could lead to odd behaviors on your Samsung TV such as no picture, Blue / Black Screen with an error message, TV headphones and base not reconnecting, no sound on TV headphones, transmitter cannot pair to headphones, etc.
Bear in mind when using Samsung Smart TVs:
- If your headphones / transmitters suddenly stopped working with your TV, it may be because your Smart TV performed an automatic update and reset all of its settings to its original form. Smart TVs also do automatic updates because they are connected to your Wi-Fi, just like a computer. Even though you didn't do anything, the TV changed itself. In these cases, follow the steps from the beginning to troubleshoot the issue.
- The TV remote control does NOT turn TV off. It only puts the TV into standby mode. The TV will still perform its "Smart" functions in standby mode. For example, the Samsung TV will still aggresively connect to all devices it finds. The best way to turn the TV OFF is to physically switch it OFF or to pull the plug.
Here is the FIX for the above issue with Avantree TV headphones and transmitters.
- REMOVE / DENY the Avantree Device from Samsung TV's "External Device List."
- Keep the TV OFF (Not in Standby) if you have any issues reconnecting the headphones and the base.
DENY the Device:
When the Samsung Smart TV detects your Avantree Device, a popup will appear on the screen, asking you to Allow or Deny the device to connect to the TV. You MUST DENY the device from connecting, otherwise it will not be able to connect with the other device in its set.
REMOVE the Device:
If you did allow the device to connect to your TV, or if your device connected to your TV automatically, you will need to remove the device from within your TV's settings.
Settings >> General >> External Device Manager >> Device Connection Manager >> Device list - >> Edit >> Select all Avantree Device >> Delete
After removing / denying the Avantree device from the Samsung TV's external device list, your Avantree devices should work properly now. If not, you might need to re-pair & lock the headphones with the base again. Here is how to do it:
1. Turn OFF your Samsung Smart TV. Either flip the physical switch on the TV, or pull the plug from power. If you cannot physically turn OFF your TV, an alternate method to try is to press and hold the power button on your TV remote for 6 seconds until the TV turns off.
2. Turn on your Headphones and Transmitter. It is recommended to have your transmitter plugged into a wall outlet, not your TV, as the TV should be off at this point.
3. Get the Headphones and Transmitter into pairing mode (rapidly flashing RED & BLUE). For more information, please refer to your devices' user manual or support site.
4. If your Headphones and Transmitter have a LOCK function, please LOCK the headphones and the transmitter together. For more information, please refer to your devices' user manual or support site.
Now, the headphones and transmitter will be locked together, so that the next time you use them they should automatically re-connect with each other and show solid BLUE on the headphone. NO need to re-pair them each time.
