K701 vs Q701? Take a look at this graph.

Could this fix some users complaints about bass? I wonder which sounds more neutral.

 

Yet, the K701 is still priced $100+ under the Q701. But this is still interesting.

looks like the Q have more mid bass, maybe 3 to 4db more ...

I'd take all their graphs with a grain of salt though. For example, their KRK KNS-8400 graph make them look like a bass monster like the 750DJ, when it barely has more bass than the SRH-440.

I think many of their graphs are just way off, but no big deal.

Later K701s are supposedly bassier, so if this is between an early K and a Q, then that would make sense to me. The graphs are pretty close, though.

Very true, not as close as this though:

I think the differences may just be the fact that the headphones aren't perfectly placed on the dummy head they use. I doubt you could tell a difference if you listened to both. You never know, of course.

Ah, that clears things up. Maybe just a bit of random variance? I certainly wouldn't buy a Q over a K, though.

Looks like the Quincy's have the same mid-bass hump as the HD650s:

... the more I compare headphones and check the graphs at headroom I get the feeling that they just alter their graphs to sell newer iterations of the same can.

(I don't wanna say they're getting paid for doing this or anything...)

 

Plus if you measure the same phone twice you won't get the same results, they differ a bit (positioning of the cans/.etc).

This said no can of the same series is identical (although 99.x% similarity) which produces slightly variations while testing.

 

There has been gossiping about different drivers/damping/interior of the K70X/Q701 but that's it.

It would surprise me if there was any official note from AKG, hell there aren't even any Mails floating around the net stating this.

Just some reading as you've made some very valid points:

There's no difference between the K701 and Q701 from 10khz to 20khz, which makes sense of the notion that foam is probably the main difference. Oh, and the Q701 has replaceable cables.

post #12 of 45

I've read enough stories of different K701s sounding radically different that I wouldn't read anything into those graphs.  People posting their HD-800 and LCD-2 graphs proved the considerable variation that occurs during manufacture.

post #13 of 45

Actually Audeze pointed out that most of the variation in their graphs is from the testing equipment, not variation in the headphones themselves.

post #14 of 45

Thanks for that. I wonder what the story is with the HD-800 measurements then.

post #15 of 45

Has anyone yet directly compared the K701 to the Q701?

 

At the very least, the newest 701's seems to have more bass according to some, and the graph up above agrees with that.  So ...  could be some truth there.
