When facing the problem: Bluetooth headphones are experiencing a delay while in use. This delay can become especially noticeable when playing games or other activities that require real-time audio. This article describes the causes of the delay and provides workarounds.
Demo environment: AirPods & iPhone 15, iOS 165.1
Solution: Update the Bluetooth driver or replace a Bluetooth device of a higher version.
Bluetooth technology is constantly being upgraded, and new versions often offer better performance and stability. Make sure that both your device and your Bluetooth headset are using the latest Bluetooth version, and you can resolve compatibility issues by updating your device's Bluetooth driver or replacing it with a Bluetooth device that supports a later version.
Workaround: Avoid sources of interference or change the frequency band used.
Other wireless devices, microwave ovens, Wi-Fi signals, etc., can interfere with the Bluetooth signal, causing delays. Try to avoid using Bluetooth headphones in environments with sources of interference, or try changing the frequency band of your Bluetooth device to reduce interference.
Solution: Choose a Bluetooth headset that supports low-latency encoding.
Some Bluetooth headsets support low-latency encoding, such as APTX Low Latency. This encoding can significantly reduce the latency of audio transmission. Make sure your device and headphones support this encoding and enable it when you connect.
Workaround: Replace the device with a higher performance.
Some older or poorer devices may not provide enough computing power to process Bluetooth audio data, resulting in latency. Consider replacing with a more powerful device to increase your audio processing capabilities.
Workaround: Update the system or app and try a different device.
Make sure your operating system and applications are up to date, as updates often fix some issues related to performance and stability. Also, try using different audio generators, some of which may be more efficient at handling Bluetooth audio.
Solution: Make sure the Bluetooth headset has enough power.
A low battery may affect the performance of your Bluetooth headset, including causing audio delays. Make sure your Bluetooth headphones have enough power and charge them if necessary.
1. Use professional audio equipment: Some Bluetooth headsets or adapters designed for audio transmission may provide better performance and reduce latency.
2. Reduce the connection distance: In Bluetooth transmission, the connection distance is too far which may lead to weak signals and increase latency. Try to keep the connection distance between Bluetooth devices as short as possible.
3. Use a wired connection: If the latency problem cannot be solved, consider using a wired connection, especially in scenarios that are very sensitive to audio latency, such as gaming or production.
With the above methods, you should be able to solve the problem of Bluetooth headset delay and improve the audio experience. Try different workarounds on a case-by-case basis to find the one that works best for your device and needs. Hopefully, this article has provided you with effective guidance to solve the Bluetooth headset delay problem.
