My liberty 4 sounds is hurting me

I bought my soundcore liberty 4 but his signature sound and most of the other presets is too acute/high in my hears, is it normal? The instrument’s sounds are amazing but when the voice singer’s gets in, its a very high-pitched and flat voice, and it end up hurting my ears and I have to listen in a 50/60% maximum volume… can someone please help me with a good configuration for that?
