I need some advice on how to increase the volume of my music

I’m interested in headphones and not speakers because I can’t turn up the volume very loud when listening to spakers.

Are you referring to Bose speakers or headphones? I know that Bose makes both and I find their speakers very weird because they do not faithfully reproduce stereo sound. Instead they “throw” different instruments to different weird locations in the attempt to make the music sound exciting. But the producers of the music never intended the horns to sound like they are coming from the ceiling (for example) and for that reason, I just find Bose speakers to be very strange. I have never liked them.
