The correct order appears to be:

HP1: LCD2r2
HP2: K701
HP3: Bose QC15
HP4: K550
HP5: Beats Studio
HP6: Crossfade

 

Taking the perceived spectral balance plots into account some listeners had problems getting proper seal with the AKG cans. This would also explain how some reviewers say their K701 has enough bass ("bass-heavy" version*) and others say it is lacking bass.

*) The old "explanation" was that there are huge manufacturing variations leading to bass-heavy and light versions..

 

Yes, I think the paper shows that bass leakage was more of a problem on certain headphones than others. See slides 34 to 39.  HP2, HP4 and HP6 tended to have more variation in measured in-ear response across subjects due to headphone  fit / air leaks.  You see the same variance in listener preference for different IE monitors if they don't have a good seal. 

 

Once people are presented the same signals at their ear drums, they will agree more on what headphones they prefer. Easier said than done.

Yeah, in case of IEMs the lack of seal can completely destroy the sound quality.

 

Btw, was the Crossfade the "LP" model?

That's a good bet since the rest are cirumaural and the M100 didn't come out until after the study. Certainly not the best showing from V-moda, even on the bassy front.

 

I was somewhat surprised by the lack of Senn's 5x8 or 6xx models as they seem to be natural competitors to the K701 and offer admirable measured performance.

+1 on that.  I'd love to see how the HD 600 fares.
