I`ve got a slide volume control on my headphones cord (right at the point that the two ear wires form the y). My personal walkman also has a volume control (analog) in the form of a dial. I keep the dial at about the three quarters level. The slide control on the headphones cord is adjusted according to background noise and comfort, but usually kept at about a quarter of its potential. The walkman is pumping out the volume at three quarters power and the slide control is knocking it down to about a quarter of that.
The question is; How is the battery consumption affected by this?
I sense that it is not the most efficient way to use the thing, am I right?
Or, are the batteries working as if I am listening at three quarters level all the time? Or is it somewhere in the middle?
I`m thinking that there is some power loss through the slide level.
Don`t be afraid to get into series and series parallel circuiting in your explanation.
