Just regular music. Yes with the bass switch the sound is warmer and I can hear a tonal change overall. With the presence switch on itself, bass felt punchier and less prominent.
With both switches on though, is sounds just like the switches off and just louder. There are some minor differences in the treble region that I can hear but the difference is quite small. I A/Bed about 15 songs and volume matched in middle of a song and to my ears it just sounds like the switches off and 1 click higher in volume.
Maybe I just don't know how to listen to the differences, I felt most of the treble region is brought forward equally just like the mids. I remembered Alf saying that the presence is everything from 5,3KHz and above.
