The Xiaomi 14T Pro uses stereo dual speakers, which will have a stereo-centering effect when the mobile phone is placed horizontally. The up speaker uses a combination of speaker and earpiece. The down speaker is an asymmetric design with a separate BOX. If you feel that the volume of the up and down speakers is inconsistent, please first exclude whether the protective film and leather case of the mobile phone has blocked the earpiece, and then confirm whether the speaker position of the mobile phone is dirty. You can try to use a dust-free cloth to gently wipe and remove it. If you are not satisfied with the stereo centering effect on horizontal and vertical screens, you can adjust the audio equalizer in settings to optimize the sound effect.
