if that's all you have, than that's all you have, and just make the best of it. i personally know what its like to not have any nice equipment, and to have to just use what's available. if you have the option to get some nice speakers, that might be a better option, but if you'd rather have headphones, i'd try to get some better quality headphones than iphone headphones (also not go ear buds, but over-the-ear headphones can sometimes be much better). these are just ideas and everyone hears things different, and everyone has their own preferences. if you like the iphone headphones and can get a sound you like, i say go for it!
