i put cutton in apple earpods, some serious base. i taped the earpod with a sealatape and took a some cotton and compressed it into a ball and put it in the sealatape, and cut a piece of an empty tube from a pen, cut that in two and put it on cutton in earpod between sealatape and taped it to the tube. may be a wider tube is better but i can’t find a wider tube at home. take a ear plug, cut it in half and make a hole in it. which i had before. and put the tube into a hole in the earbud. at higher volume you have better bass, but cutton prevents high volume highs from going through and bass goes through the cotton. the idea is that when you press the earpod to ear you get better bass, and by sealing earpod with a sealatype you make a seal and direct sound to the tube into ear and cushon it and make a seal to the ear with ear plug. some serious base. this is with apple iphone earpod, or may be ipod earpod because this one has no remote. may be ipod touch or ipod nano. not sure if you get this base on other earplugs, probably definitely more base. anyway, this is the mod i made on my apple earpods. which have almost no base on its own. you might get a slightly more base on it’s own on apple earpods if you pug half of earplug in each ear and pug apple earpod on. you put higher volume and get more base.
highs and mids a slightly muffled, may be can get better or something, but who cares it’s good base with nice descent rumble. and does not hurt ear because of cotton reduces the volume and gives nice base.
it probably works the same with fx3x.
