Headphone dampening material

Headphone damping material can be used in headphones to tame treble peaks. I found this very good article on it at Diy-audio heaven:

I also found a post on the different materials that can be used as headphone damping material:

  1. Foam
  2. Paper (Including Toilet paper)
  3. Felt
  4. Cotton
  5. Polyester Batting
  6. AcoustaStuf
  7. Asphalt sheets
  8. Dynamat or similar knockoff
  9. Butyl sheets
  10. Transpore tape
  11. Sorbothane

Problem is damping can also add bass distortion as per this article:

So I would like a material that has the smallest impact possible. Then just add layers till the treble is more comfortable. Does anyone know which material is best for this? I cant seem to find anyone selling foam or anything designed specifically for headphones.

Just out of curiosity.
Why damp headphones and not EQ the just treble section (frequency range if needed) what you want?

Of course you would need very good EQ, but anyways it would only change the area you tinker.
Even better if you can measure the changes and tinker at the same time. Make the “curve” like you want.

Basically you damp (or might) both driver, probably not even 100% the same way since 2 installations, meaning other frequency are also effected.

E: Should have read the hole thing… but it was silly. -> In the end was the thingy
In the end there are quite a few possibilities to reduce treble(peaks) in headphones IF it is bothering you.
*When you really like the sound of your headphone as it is and have ‘read’ somewhere that it can be improved by doing this or that you should realise that these alterations MAY or may NOT be an improvement to you.
Only if the treble is bothering you in some way and want it ‘fixed’ I would recommend to look into different ways on how to achieve it. **Not just because person A or guru B tells you your headphone needs it.

Toilet paper and felt can be of help as well as some other materials as cloth and foam, sometimes pads also can be of help.
Unfortunately, not in all cases these materials can be of help as they do not address small bandwidths and only can attenuate fixed amounts above a certain frequency.
In this case targetted EQ may come in handy. This can be digital, active analog or passive.
Which one of the possible ‘fixes’ to choose may depend on the headphone in question and how and where the headphone in question will be used.

Theres a lot of situations where you cant EQ a headphone. Thats where filters become more attractive. if it worked it would make things a lot more easier.

Well could mention like 5 situations?
I would have headphones or gear that you can EQ if needed or would have built in already.

Would imagine most use headphones at home, office etc where you could.
While moving or traveling… treble might not the only thing that’s messing the sound and least of worries.
Might be doing things with wrong gear. Like rowing with a spoon.

I wish they could add some to the CA IO so I don’t get that horrendous 2000Khz spike

i use a semi thick but loose stitched biene cap when i want to tame the treble some on my t60rp’s. far as i can tell it reduces treble only. to me, bass and midrange is the same. not saying you have to wear a biene, just saying you could probably find cloth similar to it or just find a biene and cutt it up. something to try. my vote is cotton as that whats its made out of.

Because system-wide EQ may not be available/easy to install on every source device you have. Especially a problem for people who don’t want to lose warranty by rooting or reflashing their phones. Adding some damping is always system-wide and source-wide. :slight_smile:

I personally despise EQ in most cases. Due to distortion thresholds, many headphones sound like the drizzling shits when you EQ them. I think my Audeze LCD-2F was the only pair that sounded decent with EQ.
