dampening cups...is that what we want?

I already made a thread, but obviously not in the right section: http://www.head-fi.org/forums/f133/d...e-want-439991/

for those who dampened their closed cans cups...do you think it's the way music/headphones are meant to be listened to?

how do wooden cups sound like? I guess they don't resonate?

dampened sound is much tighter and drier....but aren't headphones supposed to sound like 2 loudspeakers in a home room?

Your ears are not usually inches away from home speakers so the "Back Splash" of boominess from the bass resonance off the the box disipates before reaching our ears. In cans, Especially closed cans, there is nowhere for the backsplash to go except into our ears. the part of the bass reflex we want to keep in wooden cans especially is the actual vibration and "Timbre" of the wood. Dampenning materiels help eliminate the backsplash while still allowing the wood to vibrate and give off timbre.
Many closed cans are considered "Sibilant" "Tubby" "Echo'y" because of thier closed nature so it has become the FOTM to dampen some of the bad boomy bass.

well each time I've dampened my DT770 Premium and Pro, it simply killed the resonance in the mids...the bass wasn't really changed tbh.

w/o dampening it's resonating and the sound is more "hollow", w/ proper dampening the sound is drier and much clearer...but more like in a studio cabin, the sound is not natural at all...it's like the resonances would make up for loudspeakers reverberations over room walls.

I'd say the sound is more natural...I'll try to dampen my DT770/600 again, maybe

the idea is that dampening "breaks" the back-wave resonances, where the stock ABS cups just give it you right "straight" in one piece. Dynamat sells this sort of things to install inside speakers, it "breaks" the back-wave sound : DynaXorb

that's exactly what my dampening solution does for me....but I'm not sure that it's such a good idea to break all inner cup resonances in a pair of headphones

Well, I've always thought a well designed closed-back headphone have backwave resonance in consideration during the R&D...

I've discussed it w/ a PM at beyer, and he told me that the previous company he was working for was indeed dampening the inside of their closed cans cups.

I can assure you that you can drastically kill inner resonances w/ proper dampening...the question remains: is that what we want? resonances seem to make up for the impressions of walls reverberations.

OTOH, when dampened the sound is far less colored and much less bloated.....as haloxt said, I prolly need to find an in-between

like only adding dampening in the middle, and leave the surrounding of the driver untouched(ABS plastic)
