question
Given their impedance is 60 Ohms (most portable headphones have low impedance - less than 30 ohms), will they sound loud enough from a cell phone?
These headphones are extremely efficient and you will not have problems getting enough power out of them from standard PC headphone jacks, cel phones, etc. They sound great. It will be one of the best headphone purchases you've made under $100. The only thing is that the metal headband easily catches one's hair. So be careful when removing them! I have pulled hairs out!
