What to do if the karaoke Bluetooth headset is delayed?

National Karaoke Bluetooth headset delay can be solved by using a low-latency codec, turning off the system's audio enhancement function, adjusting the application's settings, using wired headphones, and updating the system and applications. Detailed introduction: 1. Use a low-latency codec, such as aptX LL (low latency) encoder; 2. Turn off the system's audio enhancement functions, such as sound effects, equalizer, etc.; 3. Adjust the settings of the application, such as adjusting the audio buffer Area size, select low-latency mode, etc.; 4. Use wired headphones, etc.

The operating system of this tutorial: ios16.6 system, National Karaoke version 8.15.38.278, iphone14 mobile phone.

The delay problem of National Karaoke Bluetooth headsets is a very common situation, mainly due to factors such as the characteristics of Bluetooth transmission and the compatibility between different devices. Before we can fix the latency issue, we need to understand what's causing it. The delay is mainly caused by the following aspects:

1. Signal transmission delay: Bluetooth headsets communicate with mobile phones through Bluetooth protocol. It takes a certain amount of time for the signal to be sent from the mobile phone to the Bluetooth headset. This time is the signal transmission delay. .

2. Encoding and decoding delay: The Bluetooth headset decodes the received audio signal and outputs it. The decoding process also takes a certain amount of time. This time is the encoding and decoding delay.

3. Delay compensation: In order to ensure audio and video synchronization, the system will perform delay compensation on the audio to make the playback time of the audio and video consistent. The delay compensation time will also cause the delay of the Bluetooth headset to increase.

In response to the above reasons for delay, we can try the following methods to solve the delay problem:

1. Use low-latency codecs: Some Bluetooth headsets support the use of low-latency codecs. For example aptX LL (low latency) encoder can significantly reduce the delay time between encoding and decoding. When connecting a Bluetooth headset, you can choose to use a low-latency encoder in your phone's Bluetooth settings.

2. Turn off the audio enhancement function of the system: Some mobile phone systems will provide audio enhancement functions, such as sound effects, equalizers, etc. These functions will process the audio, resulting in increased delay. You can try turning these features off to reduce latency.

3. Adjust application settings: Some applications will provide setting options, such as adjusting the audio buffer size, selecting low-latency mode, etc. You can try adjusting these settings to reduce latency.

4. Use wired headphones: If the delay problem cannot be solved well, you can consider using wired headphones to avoid the delay problem caused by Bluetooth transmission.

5. Update the system and applications: Update the mobile phone system and applications to the latest versions in a timely manner. Sometimes software updates can fix known delay issues.

It should be noted that since the Bluetooth headset delay problem may involve multiple factors, different devices and scenarios may require different solutions. If the above methods cannot solve the delay problem, it is recommended to consult the Bluetooth headset manufacturer or professional technical support staff for more specific solutions.
