A few phones are designed to be driven at 120 ohms, so they will sound as intended out of a 120 ohm jack. Most modern component headphone outs are 32 ohms, pretty close to a 0 ohm jack. Older high-end receivers or amps may have higher impedence jacks. I have an old NAD receiver with a 220 ohm headphone jack.

But if that same source is connected to an amplifier or a receiver with a lot of extra juice behind it, then your necessary impedance balance needs to match that perfectly. As a general rule of thumb, traditional headphone jack impedances are pegged pretty much between 0.1 ohms and 24 ohms.

Mac can detect the impedance of the connected device and will adapt its output for low- and high-impedance headphones, as well as for line-level audio devices. When connected headphones with an impedance of less than 150 ohms, the headphone jack provides up to 1.25 volts RMS. For headphones with an impedance of 150 to 1k ohms, the headphone ...
Speaker Impedance Explained - Ohms

A 4 ohm, an 8 ohm and a 16 ohm cabinet all connected to the same amplifier (1V out) would draw currents of 1/4, 1/8 and 1/16 amperes, for a total current of 0.4375 amperes. Impedance is 1/0.4375, or 2.286 ohms. (Using a calculator with a 1/x key makes this really simple.

But anyway if you look at the graphs which I assume are correct, you can see that in the audio frequency range most headphones have a fairly small reactance compared to their resistance. And most headphones have an impedance around 16-32 Ohms with some crazy "audiophile" headphones having higher impedance (e.g. 300 Ohms).

You could check the TV output and the wiring at the pot to see where the signal is being lost. Click to expand... thanks, i will get a spare speaker at work and connect up a short 3.5m audio jack, plug it into the tv and see what happens. i will also check settings on the tv. C.

it doesnt work that way. ohms is a measure of resistance, or impedance which is used on headphones along with sensitivity to show how hard headphones are to power. while ohms generally get used for headphones to describe what headphones an amplifier can handle the often left out part is sensitivity which can affect the outcome as well. for simplicities sake …
[SOLVED] Impedance of earphone jack on standard PC?

Audio gets picked out of the hdmi at the projector, and sent back to the sound system. For translations, we will require sound on my pc jack: 1. A low impedance Earphone feed AND. 2. a feed to the auxiliary room for an amplifier AND. 3. A feed to the sound system (for the bits the guys do not translate).

80 ohms is fine on PC. 250 ohms requires more power to drive so it'll sound quiet or not work off the motherboard audio jack. Need a external DAC / AMP to drive a 250ohm headphones. 1. level 1. silkandsewer. · 11m. You need an amp for the 250. Get the 80 instead. 1.
