K 701 above, modded Unipolar below. Though that's an older Unipolar measurement, before I added the moisture guard to the front.
 
There's not much point doing a listening comparison between the two phones since I fundamentally don't like the way the 701 sound. They're inferior to the Unip technically as well - wonkier frequency response, slower decay, and more harmonic distortion. But for the sake of having done it I'll attempt a quick comparison in a day or two.

They got a wonky and plasticky sounding treble range with a hint of brightness. I always found it funny K701 users saying that you need a $1000+ amp to fix the craptacular FR/sound of the K701.

Each to their own. I don't know what kind of music you guys listen to but for me k701 is a superb headphone. There is no point in discussing these different points of view at all.

Nice to see how stereotypes started by Uncle Eric in 2006 still live on this forum. What exactly is that "plasticky" sound of the treble? I thought it was the mids that sounded plasticky.

The K 701 sounded quite good for acoustic guitar, not so much for other types of music I tried.

That the Unipolar are better is not just my personal opinion, however, but a fact supported by measurements. Faster decay, smoother response, and less harmonic distortion. Also, of my vintage headphones, it's not just the Unipolar that are technically better than the K 701.


Yeah, everything was better before. Isn't your purpose on this forum to persuade everybody else that is true?

Yes and Uncle Erics description is the best way of putting it. The treble sounds bright and hollow with certain recordings, like you hear it is there but there is no sense of impact or texture from the treble (especially with vocals) to the ears, just a bright shrilling sounding treb range. People who use to say you need beefy $1k+ amp's to tame down the sound of the K701 is on crack, as amplification can't fix a engineering defect either with the way AKG tuned the drivers or the housing.
 
My blame is on the housing.
