In this case its called over modulation. You could try going into settings, sound, and scroll down to media audio effects, phone speaker. Its set at default to BASS PUNCH. Try putting on something like BALANCED. Its asking alot of a small tweeter to take the boom of some peoples voices. Try this, I'll bet it helps
