Get earphones with the rubber tips (not the old style ear buds which frankly don't seat properly). Make sure you use the correct size rubber tips (S, M, L) & make sure you get a proper seal with them or the bass will be out.
Get some closed cans (sealed headphones, not the ones with vents on the outside those are open cans & will annoy everyone near you).
Listen to music that has some bass.
Watch your hearing!
