Audio Lag with Avantree Transmitters

Audio Delay with Avantree Transmitters

Audio lag can occur if your Avantree transmitter and receiving device don’t both support low-latency Bluetooth technologies like aptX Adaptive, aptX Low Latency, or Auracast. Using compatible devices ensures minimal delay and a smooth audio experience.

Quick Check:

✅ Make sure your headphones or speakers support aptX Adaptive, aptX Low Latency, or Auracast.

✅Check transmitter indicators

● Verify the transmitter shows the correct low-latency codec indicator (model dependent).

✅Reduce interference

● Move the transmitter closer to your headphones and keep it away from Wi-Fi routers or other Bluetooth devices.Use certified products

✅Use Bluetooth SIG certified devices that specifically list aptX Adaptive, aptX LL, or Auracast support.

Why It Sometimes Doesn’t Work

1.  Headphones lack low-latency codecs

● If the headphones only support standard Bluetooth audio (SBC or AAC), some delay is expected.

2.  Apple device limitations

● Current Apple headphones (such as AirPods) do not support aptX Adaptive, aptX Low Latency, or Auracast, which can cause noticeable delay.

3.  Incorrect codec connection

● Some headphones support multiple codecs but may default to a standard one if not paired properly.

4.  Wireless interference

● Nearby Bluetooth devices, Wi-Fi routers, or long distances can increase latency

●  Older or incompatible devices

Some older Bluetooth devices do not support modern low-latency technologies.

✅ To ensure optimal performance, we recommend using Bluetooth SIG-certified products that support these technologies. You can find compatible products from certified websites:

● Products | aptX

● Find an Auracast™ Product | Bluetooth® Technology Website

💡 Please note that current Apple products do not support these specific technologies, which may result in latency issues for AirPods users.

Our newer models, such as Voyager, C82, and DG60R, also feature LE Audio Auracast technology, enhancing audio quality while minimizing latency.
