Question: Acceptable range of headphone impedances for iPod amps?
Question:
Anyone know the acceptable range of headphone impedances for modern personal iPod-type MP3 players & walkman-type CD players? My understanding (not positive) is modern headphones range about 24 ohms up to 400 ohms for pro DJ models. I want use 1970 stereo headphones which are 8 ohms impedance, and want to know just how reckless that would be, or if that's close to within the acceptable range. Thanks, - Goodmusic |

You should be using headphones of greater than 40 ohms for your iPod
player. The higher the impedance, the better for it. If you use the 8 ohm headphones, most likely the sound will be very low in volume from being loaded. Also, the batteries will probably run down much quicker. -- Jerry G. "Good Music" wrote in message ...

Some of the more intelligent driver chips might even interperet 8 ohms as "shorted" and shut down to protect itself. |

Some of the more intelligent driver chips might even interperet 8 ohms as "shorted" and shut down to protect itself. Thanks all for your responses. I was going to put an 8 ohm resistor in series with each channel headphone to bring it up to 16 ohms, though that would halve the voltage (& presumably volume) the phones would get, but now I'm worried even 16 ohms may be too low... I've heard of "impedance matching" but don't really know anything about it, I'm posting a new query asking how to make an impedance matching headphone adapter (hopefully can make it just using a small audio transformer installed in each of the large old-style earcups...)

You're wasting your time. A couple of good quality audio transformers will cost vastly more than a new pair of headphones. Look at Sennheiser and Beyer btw. Graham |

Oh, for goodness' sake! Plug them in and try. If they don't sound good buy different headphones. |

The amount of complete and utter drivel any number of ppl have written about this begs belief ! Graham |
