There are 32 ohm headphones that need a strong amplifier to be driven. Ohms are only one factor in the equation of why a headphone needs to be driven. It typically works well for headphones under 150, but after that they're all over the place and shouldn't be trusted alone.

I never said very well. I said pretty well. Obviously an amp would be beneficial, but an MP3 player should be able to drive a Q701 quite a bit better than a K701.

MP3 player doesn't drive anything. A soundcard doesn't drive anything unless it has a standalone amp attached.

You can listen to the Q701s on an mp3 player, but that doesn't mean it's being driven in any manner.

I've yet to see any measurements confirming either case.

I think you dont understand what 'driven' means here. Driven just means you can plug it in and play music through it. This does not mean it sounds good by any means, but its still driven

Don't all soundcards have output opamps anyway?

There is generally some line output driver op amp like a NE5532 (in large quantities, a ~$0.30 part or so) or some such, probably a resistor after that to increase the output impedance to a level typical for most line outputs—100 ohms or so maybe.

Modern cheap audio op amps can have very good performance, but if it's just intended as a line output, they will not use a high-current output part. Great performance connected to an amplifier does not mean there will be great performance driving headphones directly. It may not be suited at all for driving low-impedance loads like headphones, though some should manage okay, particularly if you're not maxing out the volume. Then again, sticking a big resistor on the output is not really suitable for a lot of headphones either.

Do you consider that to be "driven" or not?
post #12239 of 38154
Yeah, I'm with the previous posters here. How exactly do you define a headphone as being "driven?" On a related note, at what point do you consider it to be "driven properly/adequately?"

I wouldn't say getting sound from a headphone is being driven. I would say allowing a headphone to reach it's optimal state through amping would be driven.

I consider headphones producing sound, even without an amp being "run." You can run DT8880s on an mp3 player, but that doesn't mean the MP3 player is DRIVING the headphone. It's simply allowing it to run.
