RAA measurements (artificial head)

Other Kennerton Thekk measurement (flat baffle).


For all those who would think that the Thekk lacks bass and extension in the sub-bass, here are my own measurements of the Kennerton Thekk versus the Thror and the Odin mk2, measured on the same measuring platform, a flat baffle consisting of the leather seat of my sofa and the use of a professional portable measuring microphone PHONIC PAA3: dynamic range: 30 to 90 dB SPL; each horizontal line corresponds to a sound level difference of 10 dB SPL (floor at 30 dB SPL).
The left-most vertical bar corresponds to the global SPL (all frequency) and reflects the difference in average sensitivity of the 3 headphones listened to on the same amplifier (pink noise) with the same volume position of the amplifier knob for the 3 headphones (Nb: the Odin being the headphone with the highest average measured sensitivity: 97.5 dB SPL; the Thror, having the lowest sensitivity measured: 93 db SPL).
The measurement trough at 6 KHz is probably a measurement artifact; on the other hand, the frequency peak around 9-10 KHz is well present.
To obtain a good seal of the pads on the measuring rod, I exerted a rather strong pressure on the pads, as you can see on the pictures.

EDIT: 3 new measurements of the same Kennerton headphones (Odin mk2/Thror/Thekk), with a pink noise level 10 dB SPL higher than in the first measurements above, to further improve the signal-to-noise ratio, especially in the sub-bass.
(NB: Measured frequencies: 20 Hz/25 Hz/31.5 Hz/40 Hz/50 Hz/63 Hz/80 Hz/100 Hz/125 Hz/160 Hz/200 Hz/250 Hz/315 Hz/400 Hz/500 Hz/ 630 Hz/ 800 Hz/ 1 Khz ... etc.).

I visited the Fischer Audio workshop today and once again enjoyed the atmosphere of creativity. What a smell there!

I also bought these incredible headphones. This is not a review, but simply first impressions. This is just the best I've ever heard! Incredible sensations of space and live sound. It seems like you can even touch sound with your fingers. I will write my full review later. I want to burn in them and add a balanced cable

Congratulations! :)

This headphones is gorgeous!
And the sound is wonderful too.

Along with the Magni, the Thekk is Kennerton's greatest achievement!

Congratulations to the team! :)

PS: Good burn-in with your new Thekk.
This morning, I just put mine (my Thekk) in burn-in for a week ... In the meantime, I'm listening to the Thror.

Congratulations! :)

Thank you!

Good burn-in with your new Thekk.

BTW guys did not recommend burning-in without listening on the head. The membrane should have a feedback (back push effect) from some kind of obstruction (your ear for example). If this does not happen, then it is not very good for the membrane

Thanks for the advice ; I just created an artificial head for the burn-in of my Thekk : pink noise measured at 87-88 dB SPL ; let's go for 1 week ...

Yes this should work fine

BTW today I personally made sure that burning-in affects the sound quality. I first listened to burned-in Thekk and then a brand new Thekk. And I immediately noticed changes in the sound and even asked Pavel why the sound is different. The sound was less weighty and a little quieter on the new headphones

Good morning, everyone.

Here's a very interesting YouTube video of the Kennerton Thekk compared to the Thror.
Very well constructed video; you can use the subtitles translated from French to English (or any other language) for comments.

For the reviewer, Pierre Paya, the Kennerton Thekk is the most beautiful achievement of the Kennerton brand to date.

Hi all.

Pierre Paya, the author of this first YouTube video (below) of the Kennerton Thekk, wrote, in the French forum, about the Thekk.
(after translation into English)



"Hello Eric,

Yes, good screenshot!
Thekk is going to be a success I think, at least, it deserves to be.

For me it is not only Kennerton's biggest success to date, but it is also, right after the Susvara, the best orthodynamic headphones available today."

Good morning, everyone.

I've just translated, into English, the French text made by Pierre Paya about the first YouTube video of Thekk compared to the Thror, taken as a reference headphones.

At the end of this long translation of the text of this french video (in spoiler) you will also find some comments from me about the Thekk.




" Good morning, everyone.

Today, I'm going to share with you my listening impressions on a product from the latest generation of Kennerton headphones, you know that brand made in St Petersburg, Russia that you are now familiar with.
Well this headphone is the Thekk; here is the Thekk, well, we'll listen to it together.

Here is this Thekk, with the new headband that Kennerton is putting in place on his headphones; a new system of suspension on the head, by elastic, very simple, but much more efficient (practical) than what Kennerton proposed before.
So afterwards, the aesthetics are similar to the Thror or Odin, although there are some differences, even in the machining of the wooden cups; see here, for example, with the junction of the pads there (for the cups), there is no thickness at all; it's very thin; whereas if you take the Thor, you see there's an extra thickness of wood here ; so there are small differences that make the wooden cups (of Thekk) thinner in fact.
The grid, also here, which protects the external side of the drivers (of the Thekk), is quite different (from the Thror).
The internal damping system (of the Thekk) is a little bit different from the Thror's as well.
And then the pads too; so, pads like this, externally seem to be the same (as those of the Thror), but in fact, the perforations (of the Thekk) are of a larger diameter than the perforations you can find on the Thror's pads and even the pads of the New Odin.
So, all these are small differences, which will make this Thekk sound different from other Kennerton headphones, even though it has the same drivers as the Thror: we have a honeycomb structure membrane and the frame between which the membrane is stretched is made of carbon fiber, just like on the Thror.
In terms of weight, this Thekk is very very light: 350 g against 480 g for the Thror.
The impedance is the same, 35 Ohm; so of course, for both: we have the same drivers; and the sensitivity is the same, at 100 dB / 1 mW.

Here is the system I used for this presentation of the Thekk; so as a source, and to stream Qobuz directly connected to the Internet, the Fidelio network/dac player from Liedson, then I chose the Viva 2A3 amplifier, and as a reference the Kennerton Thror headphones.


After nearly 200 recordings of Antonio Vivaldi's Four Seasons, here is the work of the red-haired priest reworked by Max Richter, and performed on the violin by Fenela Hamfrey. So as long as we accept this great difference that takes us away from the original writing, well, this album is a real treat. Here, the first part of the Winter, on the album Winter One. (music)

I listened to this music with a maximum peak level of 75 dB at 2'50.
So I perceive the first violin better centered with the Thekk than with the Thror. At the same time, this violin is a bit less biting, a bit less a bit less prickly with the Thekk as well; it's actually more elegant, more graceful, more subtle. The Thekk's treble is a little more open; I can hear it well on the introductory harpsichord.
And then something bothers me with the Thror, in fact; a little coloration in the upper midds; a kind of cardboard sound, a bit like the upper midds of the violin, well, it goes through a little cardboard cone; uh, I hadn't perceived this little coloration (of the Thror), but direct comparison with the Thekk allows me to identify it.
Continuing with the Thekk, I hear a freer sound and freed of some small resonances that I perceive in the low register with the Thror.
Well, so nothing really annoying, the comparison with a reference, here with the Thror, just makes me right, once again, that it proves its relevance.

Well, so nothing really annoying, the comparison with a reference, here with the Thror, just makes me right, once again, that it proves its relevance. But it's true that without a direct comparison, I can listen to the Thror, and I don't think that these resonances (of the Thror) are really disturbing.
In fact, in analogy with the photo, I'd say that the Thekk makes a more precise focusing on the orchestra, and that with it, the violin stands out better from the ensemble; whereas it blends more with the mass with the Thror.



An album of gypsy jazz, called GIPSY VIOLIN, and I chose the track l'Ora du Berger.
I listened to this music with a maximum peak level of 72 dB at 0'30. (music)

The violin is here centered slightly to the left, and I can see this clearly with the two headphones; but here again, it is more precisely drawn in space, for me reproduced by the Thekk. The violin, again, is more velvety, with the Thekk as well.
In fact, the direct comparison makes me hear that the Thror's treble is a bit rougher, precisely compared to the delicacy of the Thekk's, and that it's also a bit less open. I also have a better notion of rhythm with the Thekk.
So it's not a question of dynamic range, which would be less extended with the Thror; no, no, the Thror is just as dynamic as the Thekk.
This better perception of rhythm (with Thekk), I think, is due to the fact that Thekk better separates each note, each desk, and gives me a better overall reading of the whole; a better representation, in fact, of each musician's playing. I can then more easily follow the rhythm that each performer instills in his or her own instrument. For example, the double bass pizzicati are more frank with the Thekk, and the double bass is always more incisive; I can perceive the plucking of its strings more acutely.
So here are some little things that contribute, for me, to a better perception of the rhythm, quite simply (with the Thekk).
Another thing, the double bass goes a bit lower as well, and it's a bit less round with the Thekk.
On the other hand, the overall opening is the same on both headphones.



A completely splendid song from Dana Winner's album PUUR.
So PUUR means pure in Dutch; so, you see, it's easy Dutch. This song has been performed many times by various artists; we all know it; but never, in my opinion, has it been sublimated as much as by Dana Winner. In fact, well by her involvement and the quality of her singing, she immerses me in the deeply charged, deeply charged with meaning of this magnificent text. "One Moment in Time". (music)

So, I listened to this music with a maximum peak level of 81 dB at 4'35.
The first piano notes, at the very beginning, are a little less scathing with the Thekk; let's say I feel a better balance with it. The Thror gives the piano a nice sparkle, though, but I'm actually wondering if it's not a bit too much.
The voice is softer, more precise and better centered, too, by the Thekk.
So yes, it's not the strong point of the orthodynamic headphones, with their very large emissive membrane, to center the sources well, and I can see it here, with the Thror; but the Thekk still draws the contours better.
Dana Winner's voice, well, it's also freer (with the Thekk), as if free of a little veil, a kind of very light filter that takes away a bit of her presence when she's sung by the Thror, with which, by the way, she seems a bit pinched to me in fact.
Ah, and yes, the Thekk here gives me more pleasure anyway; it's neat. With it, my mind focuses on the intensity of the text carried by the beautiful melody, itself raised by the lyricism of Dana Winner; so, it's very personal, but the whole thing moves me deeply (with the Thekk), while listening to the Thror, well, I realize that I'm not diving but rather trying to understand why and to identify what's hindering my immersion. Thekk makes the work occupy the time and space that are mine at the precise moment of listening; nothing more and nothing less; I am just and simply, with it, touched.



Bob Marley and his album LEGEND.
From this album which has been remastered in high resolution 24 bit 96 KHz, I chose track 12 " Redemption Song ".
I listened to this music with a maximum peak level of 68 dB at 0'40. (music)

Here, I prefer the Thekk as well, but then definitely the Thekk.
And yes, it introduces me to Bob Marley, the musicians who accompany him (on the album), the stage on which they all perform, all in a clear and intelligible way.
The Thror disappoints me a little bit here, unfortunately, because I lose with it this beautiful painting with these characters well integrated in the atmosphere of the concert. I also lose with him a little bit of hindsight. The Thror, always, produces some resonances, as we saw, by the way, listening to Vivaldi's Winter of the Four Seasons ... and these resonances come to blur, alter the clarity and precision of the message, simply because they are superimposed on it.
The reading is cleaner and definitely more credible with the Thekk, even if, it must be said, listened to alone, the Thror would fully satisfy me, I'm sure of it.


Well, it's true that with this Thekk, we're still far from the first generation of Kennerton headphones that arrived on the French market in June 2015, with the Odin; Odin that here, the very first, the very first Odin manufactured by Kennerton; it was therefore in 2015; it was then posted on their website to present the brand, to present the product, and it doesn't even have a serial number.

So, it's true that over time the brand's engineers have evolved the products towards more rightness, more precision, and also to reduce the weight; so the new generation which is composed of the Magni, the new Odin and the Thekk, benefits from the new suspension system with this soft and less rigid headband than the one we have here (the one of the Odin) and that you all know well now.
The Thekk also benefits from the weight reduction, that's it; like the Thror in terms of weight, it's much lighter, but it has the added advantage of combining the light weight with this new headband.

So, it's true, if I consider its price which is lower than the Thror's, if I consider its comfort, clearly improved, its weight reduced, and then what it gives me to listen to; well for me, it's clear and I don't hesitate to classify it, and to say that it's the most beautiful realization, so far, of the Kennerton brand.

So of course, as you all know, I've been the importer of the Kennerton brand in France for more than 5 years now, and rest assured that in this type of video, I try to avoid as much as possible, of course, the conflict of interest, and that what you hear from me, well, in this video, justly, is the sincere transmission of my feelings.

Thank you.

If you feel like it, you can find us on our forum " Musique-O-Casque.com ".


NOTE: I would like to make a few clarifications: Pierre Paya distributes and sells all the headphones, dacs and amplifiers seen in this video.


Otherwise, Pierre Paya, systematically burn-in all the headphones he presents in his videos for 150 hours; one can believe, as one can not believe in burning-in process, but it is an important fact to specify.

Finally, Pierre Paya, in the French forum, positions the Thekk in relation to the other orthodynmic headphones he knows well (Audeze, Hifiman, Meeze, Kennerton, JPS ABYSS), for his appreciation, which of course may differ from ours, with this little sentence, but which, for me, says a lot :

Quote (Pierre Paya in the french forum):
"The Thekk is going to be a success, I think, or at least it deserves to be.

For me it is not only Kennerton's biggest success to date, but it is also, right after the Susvara, the best ortho available today. »


For my part, at the present time, with my equipment, the Thekk is the best headphones listened to from a long list of high-end headphones (in chronological order of listening : Stax SR-007 mk2; Stax 009; Audeze LCD-X, Audeze LCD-3F; Sennheiser HD-800; Kennerton Odin mk1; Odin mk2; Odin Thridi; Meze Empyrean, Audeze MX4, Focal Utopia, Focal Stellia; Kennerton Thror).

I think I'm going to live very happily with my Thekk ! :)

One last remark; you will follow it or not, according to your beliefs or even simply if you are curious or not, the Thekk, just like the Thror, "imperatively" require for me a sufficient break-in procedure (for me 150 hours of burning-in, with pink noise, at an SPL level of 87-88 dB) to free the headphones and give them their full potential. Once this burning-in (for me in this way), the Thekk goes from a charming headphones to a wonderful and superlative headphones.

Then, if you want to have better than the Thekk, for even more finesse, maybe you should consider the Hifiman Susvara, but it's not the same price, it's not the same quality of manufacturing, it's not the same degree of customization, and it's not the same amplification needs ...

Good morning, everyone.

The Kennerton Thekk sounds almost as good as the Hifiman Susvara; according to Pierre Paya, the Thekk is the second best ortho technology headphones for sound quality, right after the Hifiman Susvara ...

However, here are three good reasons to buy a Kennerton Thekk headphones instead of a Hifiman Susvara headphones.

1 - the price: 3 K$ versus 6 K$ (and in France: 2 850 € TTC versus 6 500 € TTC).

2- amplification requirements: Thekk sensitivity: 100 dB/mW @40 Ohm versus 83 dB/mW @60 Ohm for the HFM Susvara.
In practice, at Pierre's, the Susvara is best driven by a loudspeaker amplifier, the Viva Solista (2 x 25 W) (price in France 17.400 € TTC) while the Thekk is satisfied with the power of the sublime Viva Egoista 2A3 (2 x 3 W) (price in France 8.700 € TTC) (Note: my Viva 2A3 amp was bought half as expensive, second hand).

3- the manufacturing quality, the durability of the pads, the beauty and the originality.
The Susvara is made (manufacturing) like a toy (very very expensive): these few pictures speak for themselves ...
