When a headphone says its X ohms is the whole headphone at the X ohms or is it just the plug, cable and/or drivers etc ?
So what would happen if you put a 150 resistor at the plug? Right before the driver? or Both ? Would you get the same result as a stock 150 ohm headphone ?
The placement of the resistor wouldn't much matter so long as it's in series. Effect would be virtually the same.
The effect would not at all be like having headphones with the greater impedance. It would be more akin to increasing the amp's output impedance (reducing the damping factor and more; see other threads in the subforum). You'd be splitting the power delivered between the resistor and the headphones. For certain headphones this would mostly just reduce the volume; in other cases the sound quality and performance may be somewhat altered too.
What is it that you're trying to accomplish here?
yea, I wouldn't trust $10 soldering stations, I would rather pay for better quality especially if I were to do testing and troubleshoot.
