Method for realizing earphone return of Bluetooth earphone and related device

The embodiment of the invention provides a method for realizing headset return of a Bluetooth headset and a related device. In the embodiment of the invention, the terminal equipment can increase the size value of the cache region when the state of the terminal equipment is not good so as to reduce the load of the terminal equipment, and can reduce the size value of the cache region when the state of the terminal equipment is good so as to reduce the time delay of earphone return playing, dynamically adjust the size value of the cache region and realize low-delay earphone return. 本申请实施例提供了一种实现蓝牙耳机耳返的方法及相关装置。在本申请实施例中，终端设备能够在终端设备状态不好时增加缓存区大小值，来降低终端设备的负载，在终端设备状态较好时减小缓存区大小值，来降低耳返播放的时延，动态调整缓存区大小值，实现低延迟耳返。
