I suppose you are listening the Clip with the headphones you got with it.
If you want it louder and want to cancel surrounding noise you could for a start get noise-canceling earbuds with a decent sensitivity - the one with rubber bulbs to push them deeper in the ears. I have an pocket amp (cmoy) for home listening with a big headphones. But when working around the house (cutting, grinding and welding steel or doing other noisy works with saw and big hammer) I don’t want extra stuff in my pocket. So I got some half-decent 50€ Sony earbuds which souns rather good to my surprise (way better then the Clip headphone I must say) and doing nice job to cancel most of the noise from arround. They are also handy when I play games and I want to cancel TV and other surrounding noise.
