You must first ensure your headphone's sound quality. It should be in good performance. That means you hear clear words, clear sounds, and heart-pounding bass that you wouldn't stop dancing to. Next is the comfort that it gives. How comfortable is it? Is it irritating or too hard for your ears? Last is the matter of price. Is it affordable? Or, if it's expensive -- is it worthy of the price? Choose only the right headphones for your delicate ears.
