🔹 Bluetooth version incompatibility – if your smartphone supports Bluetooth 4.2 and headphones require 5.0+, For example, Redmi Buds 4 Pro are optimized for Bluetooth 5.3, and older devices may experience audio delays.

🔹 Conflict with other devices – if the headphones have previously been paired with another gadget (laptop, tablet), they can automatically try to connect to it, ignoring the new phone).

🔹 Software failures - bugs in the firmware of headphones or phone, Bluetooth module cache, as well as power-saving modes included (MIUI Optimization or Battery Saver often block a stable connection.
