So people have been speculating on the Dekoni Blue and what we did to the Stock headphone to make Fostex take notice and agree to make it for us.   We’re the only company who Fostex has agreed to produce a modified T50RP MKiii for and I think that says a lot.  It is said that…


OK Dekoni Fans, Here’s the latest frequency graph of the all-new FOCAL ear pads we just released.  I have these tested on an Elear headphone, just so you know.  You’ll notice, right off the bat, the differences are all very subtle for the most part as you can see from the below graph showing all…


Ok, here it is.  The long-awaited Frequency Comparison charts for the Dekoni Audio HD600 Ear pads.  Careful analysis and hours of listening go into our ear pads and we stand by our models as the best of the best as far as replacement ear pads go.  I’m going to just jump right into it.


I will say, before I continue, that you should always give new pads a few days of listening to get used to them before issuing any judgements for or against.  A pad swap is probably the quickest and most effectual mod you can do to a set of headphones so the difference you hear may be very different from the pads you previously had on the headphones.   That said, sometimes one may equate sounding “different” with sounding “worse” because it’s not the same (which they grew to like and love).  Given a chance though you may find the new pads, once you adjust, actually make a change for the better that you didn’t think was coming.  So always give pads a chance.  You Just might find they’re better than the ones you had and that’s what we do this for.


Also, note that because the Headphones are open back the sound will not change as much as they might with, say, a closed back set as you aren’t changing the inside pressure levels or air flow nearly as much.  You will see that the graphs on the 4 variants are very similar with a few minor differences.  No change is greater than 2-3db between any of the frequencies so everything is fairly subtle.  Nothing drastic happening.


First up is the most popular pad in the line-up.  The HD600 Fenestrated Sheepskin. You will see from the image below there is a fairly equal lifting of the frequency range from the bottom to about 2,000 cycles.   This is representative of the change from a rounded pad to a Squared off one where the inner wall of the pad acts more as a funnel in rather than a diffusor as a rounded pad might.  You will notice this in all the variants and they are all very similar in their response.  The lower frequencies have nowhere to go but inside your ear.  You’ll notice a slight dip then between 2K and 5K on the Fenestrated pad with the frequency response remaining almost identical up to 20K with a slight bump on stock above 15K.  All of this goes to the Dekoni pad, to my ears, sounding a little warmer.  I have felt the HD600 to be missing a little “meat’ in the mid-range and our pads seem to bring it in just enough.  


Next up is the Dekoni Sheepskin Edition.  You’ll notice it looks very similar to the Fenestrated all the way up to about 12.5K where there is a significant amount of the high frequency material that is maintained, instead of lost to the stock Velour pads.  To my ears, this pad cuts the frequencies in the “conchal bowl” enough that they sound more neutral in this configuration.  Instead of seeing a boost in the low and boost in the high, picture if you increased the amplitude of the Sheepskin pad graph and it would invert to a slight dip between 3K and 10K, where our ears are most sensitive.  This is due, again, to the sheepskin surface directing all the frequency material from the speakers into your ears instead of the loss you experience into the pads.


The Hybrid pad is very similar to the others in the sub 2K range but above that it is almost an exact frequency match with the Stock pads.  These sound a little louder than stock (less material loss) with a slight screen on the high end which seems to even out the tone of the headphones.

Now, on to the Elite Velour model which matches very similarly to the Fenestrated Sheepskin as well with not quite as much of a rise above the 2K Range but some is still present.  These pads are extremely comfortable and seem to maintain a lot of the Primary characteristics of the HD600.

That Folks, is one opinion of many but it is mine and I’ll stand by it!  Thanks for reading an I hope that we have made a pad for the HD600 that people will see as an upgrade and an update to the stock pads.  If you want to discuss further please feel free to reach out to me personally at the email here.

So here we are in the middle of another run of the X00 Pad from us, Dekoni Audio on Massdrop  I wanted to personally reach out again and Show some frequency graphs of some comparing I did.  I’ve been testing and tweaking as we design in our lab and we have some really great things coming.  I wanted to show the sonic differences in between the options here as they appear in an objective (as close as we can get anyway) testing scenario.  We have designed a special testing “head” mic that is designed to mimic the human head and auditory system as closely as we can.  It’s not perfect but for the purpose of comparing it works fantastically.  We run Pink noise though the headphones and use specially calibrated microphones on each side of the head mic to gather the data.  For those of you that do not know what Pink noise is, it is every frequency from 20-20,000HZ (the human hearing range) played at the same time and at the same volume, or amplitude.  What this allows us to do with specially designed software is measure each and every frequency and how the headphones play the sound.  Headphones don’t play all frequencies at the same volume and this is due to a variety of factors I won’t get into here.  The graphs below all show the X and Y axis.  The X axis is the frequency range from 20hz-20,000HZ and the Y axis is amplitude, or volume.  So the “higher” the graph along the frequency range, the “louder” that frequency was in the testing.  Also note that for every 6db in Sound pressure level increase/or decrease, you are effectively doubling, or cutting in half-depending on which way it goes, the volume.  for example, 85dB is twice as loud as 79dB and only half as loud as 91dB.  SO now off to the graphs.  FYI, All ear pads were tested with the test material at the same level so as to provide accurate comparison.

The first one here is all the iterations of the X00 pad.  You’ll notice the biggest differences come in the lower frequencies (below 500hz).  From the testing I did it seems that the attenuation ring does bring the low end up a decent amount though no increase is more than 3db (which is half the volume).  There is also a boost, however slight, in the upper registers too whoch contributes to the clarity of the headphone.  The pad that tested closest to stock is the Sheepskin with no ring but there is a fairly noticeable dip around the 500hz-1khz octave that may attribute to people saying they like the mid-range better on the Dekoni Pads. Those frequencies are the “nasal” frequencies and they can be harsh to some.

The Graph ABOVE Shows the Stock pad vs the Sheepskin Pad with the attenuation ring.  In the sub-bass frequencies (where the headphone sounds nice as it is) you find a pretty good bump and that helps bring those sub frequencies out which, IMHO, really makes the headphone shine.  There is also a bit of brightness and clarity that comes with the Sheepskin pad with the ring that you don’t get with the stock pad.

Next up is the Sheepskin pad with the ring and without.  It’s a very similar response as with the above measurement.  The bass is given a small boost as are the higher frequencies.  Again, it’s all very slight but noticeable to some people and not so much to others.


Down below 500hz, where most of the change in the sonic signature between the pads originates, is highlighted below.  You can see that each pad is fairly consistent in it’s amplitude difference compared to the others which I found to be interesting.  Again, the addition of the Attenuation ring seems to funnel the low frequencies somewhat and bring them to the fore.

The Final Graph in this series is one that highlights the differences between the ear pad configurations above 2khz.  Around 2.5Khz we have a convergence where they all show roughly the same response and then the attenuation ring containing configuration become more dominant again.  I’ll note the difference looks large but between the upper and lower lines the difference is only about 2db.  It’s just enough I think to bring a little shine out of the headphones as others have said.


That is all for now.  I see that people are interested in the TH900 pad and how it works with the Fostex X00.  I can run the comparisons on those too.  To my ears, the TH900 Sheepskin pad we sell opens the headphones up quite a lot.  It’s definitely different- and when there’s a difference, some people will like it and some won’t.  one thing I always keep in the back of my head is that ALL of this is subjective to what you’re listening to.  Our tests are run with pink noise but no one in their right mind listens to pink noise so with other material that are heavier in certain ranges the different pads might have the headphones reacting in a different manner.  It all depends. I just thought the community would like to see some evidence and then judge for themselves.   If anyone has any further questions or comments feel free to hit me up.

Ear pads are the difference between comfortable and un-comfortable headphones.  They can make or break a decision and trump other merits such as sound quality and brand preference.  Dekoni Audio Ear Pads are made to be the most comfortable ear pads available and the use of quality protein leather and memory foam we feel our…
