|   Impedence question | dtrachtman
Jan 8, 2003 9:35 AM | | I am not an audiophile by any means, but I wanted a really good pair of headphones for my ipod and computer. After some research, I determined that the AKG K240
headphones were the best for my needs. BUT, I was told
that they would be too hard to drive from my ipod (they
have a 600ohm impedence). Then I heard about the AKG
K240S which is supposed to be just like the former,
but specially designed with a low impedence so that it
can be easily driven (only 75ohms). Do you think this
means the sound quality will be decreased? If the
answer is no, why dont all headphones have a lower
impedence so they can be used anywhere?
thanks,

You always want to match the impedance. I don't know what the output impedance of your ipod is, but you want to match that with whatever headphone you choose. The 600ohms AKG K240 phones were meant to be used with a 600ohm source. |

Jan 8, 2003 11:17 AM | | ok, but is a higher impedence *better* than a lower one in terms of sound quality? |

Jan 8, 2003 3:56 PM | | It is not a matter of sound quality. It is a matter of efficient transfer of electrical power. If you get way off, either you will be underdriving your speakers( they won't have enough juice to light up the room, but your receiver will run cool), or you will be over drive your reciever(too much juice pass through it causing it to heat up). |
