The MacBook Air's speakers give little "treble" sounds. Even in normal speech (like podcasts) videos, there is a bass in the sound. Or I feel like the "bass" overtakes the "treble" in songs. For example, in songs, the voice of the instrument is heard more than the voice of the singer. Background music in movies is louder than the actor's voice. I don't know if this is the way it should be, but frankly, it sounded strange to me. What are your thoughts?
