How do you control the Anker Soundcore Liberty 4 NC?
The factory firmware of your earbuds does not include LDAC support. Therefore, it is necessary to update the firmware as per the provided guidelines. It's important to note that there may be a slight delay when using Bluetooth headphones, which is a common limitation of Bluetooth technology. In most cases, this delay is minimal and should not impact your experience. However, it's worth mentioning that the delay can be influenced by various factors such as the Bluetooth headphones themselves, the connected device, the audio source, the specific application being used, and even the network conditions.
