The wooden earcups have 3D printed waveguide cups, which make the listener's ears the focal point.

Im not super technically inclined, but I think that making them closed-back made the bass more prominent while not sacrificing soundstage as much as a traditional closed back would.

Very interesting experiment. Does it super increase soundstage?

Going closed back inherently narrows the soundstage. In this case though, Im assuming that it doesn't narrow it quite as much with the amount of room the wide earcups allow.

Is that always true? I am honestly asking, because I feel my DT770's have wider soundstage than the 6XX's I just sold to a friend. But I have never done a modification like you did to an open back to see the difference with closing them off.

You're in luck, I also have both the DT770's on hand as well as the DT990's. I just spent the last 20 minutes scrutinizing all 3, and I would say the 990's are a teensy bit wider than my 6XX, but the 770 is a bit narrower than my modded 6XX. (No EQ or Crossfeed)

I would add though, that in my possibly biased opinion, my 6XX's now respond well to crossfeed in the L and R channels. I've sometimes played sound in them thinking my monitor speakers were on instead!

Nice. Thanks for the comparison!

Closing the same design narrows the stage. DT990 is bigger than DT770, which has a rather big stage for a closed back.

6xx have a tiny soundstage even compared to closed backs, this mod would do nothing but make it smaller unless there is zero damping and the cups are giving off resonances and harmonic distortion all over the place.

DT770s are an anomaly for closed back Soundstage

Gotcha. Thanks. I pretty much only wear open backs except for two closed backs in rare circumstances. ☺️

Do you actually prefer the 770 pro?

FKSSR t1_j9hzzt5 wrote

Yes. I am one of the weirdos that prefers headphones with a bright presentation. My favorite headphones are the 800s and DT1990's. I sold the 6XX's, because they were too dark for me. I prefer the 560s to the 6XX, personally. :)

There are no weirdos here, just different tastes. In my case my tastes are completely opposite haha.

I have the 6xx, hd599, AKG k371, akg 702, Audiotechnica mx50, etc. Dt770 is the best of the best to me. I stopped following the audiophile community and started listening to my own ears

How much of the sound profile is from the weight crushing the cups into the side of the head? Ergonomics affects sound.
