Sound is low and faint
I have just been given a set of Sony headphones model number MDR-XB450AP. When plug them into my computer and my iPod touch they work fine but when I plug the extension cable that I have the volume on headphone is low and faint. I know the extension cable work alright with other heads.
Here are the photos that you wanted. Photo 1 is of the Sony headphones. Photo 2 is of the Sony headphone plug. Photo 3 is of the other headphones that work. Photo 4 is of the plug from the other headphones that work. Photo 5 and 6 is of the extension cable.
