Audio46's Opinion

If you want an open back soundstage from a closed back headphone, that’s a kind of ridiculous request, isn't it? Well, somehow, Kennerton manages to pull it off. The GH50 may have one of the widest soundstages on a closed back model, and other Kennerton closed backs share a similar width. The GH50 is extremely airy, allowing for a much more surround sound feel than a closed back is typically thought to be capable of. The sound never feels to be pushing up against the headphone’s walls, it always has extra room to breathe. The same goes for the depth, which never seems to lack the space to accommodate and bring to life even the most atypical and extreme compositions.

“When the sound completely captures you”

Kennerton Gjallarhorn – the first in the world horn-loaded headphones!

Horn-type headphones have musicality, integrity of perception, overall harmony, natural sound, and the ability to completely capture the listener.

Note: Due to the specific nature of every piece of wood each pair of wood cups can not correspond precisely to the photo on the website.


JM Edition is an acoustic modification of Gjallarhorn headphones, which was tuned by one of the first owners of Gjallarhorns.

We considered it quite worth to be a separate model and now we are offering you the official Kennerton workshop version of it.

The main differences touched the bullhorn form and change of phase inverter. It did significantly change the accent of the sound of the headphones without dropping any quality at all.

We named the model after the author, JM Edition.


The most important advantage of horn headphones is the ability to develop good sound pressure and give excellent dynamics from the first milliwatts with minimal distortions.

Horn Headphones reproduce the most subtle musical nuances and most fully and accurately convey the emotions of performers.

The horn in the headphones creates a full presence effect, gives outstanding micro-macro dynamics and a wide directional pattern in the horizontal plane.

High and medium frequencies played through a horn have a completely different energy and transparency. Low frequencies, reproduced through a horn, have a natural fullness and power.


It all started with the development of a new high-tech material called “Graphene”.

Graphene – if to explain in simple terms, is a two-dimensional sheet of carbon that is only one atom thick. Its physical properties are truly unique:

  • It is 300 times stronger than steel
  • It has no internal resistance
  • It is incredibly light

As currently the production of pure graphene membrane is very hard and time-consuming and can cost a fortune, we decided to create a hybrid of mylar and powdered graphene applied by thermal method. Thus, we were able to significantly improve the characteristics of the classic dynamic driver, such as the strength of the membrane, its rigidity and the absorption of parasitic resonances. This high-tech membrane required the corresponding uncompromising “engine”. Therefore, we have equipped the speaker with an ultra-light aluminum voice coil (CCAW), covered with a very thin layer of copper to increase its conductivity. And the coil is set in action by a powerful magnet made of NdFeB alloy, which in size and power of the magnetic field exceeds 3-4 times the magnets of similar speakers from competitors. All these engineering solutions gave the speaker a high dynamic range, stunning detailing of sound, and very low distortion, and brought the sound quality of the speaker close to the representatives of the planar-magnetic technology.

Over the past year, we have created several promising headphone prototypes based on these developments, and one of them was even released for one of our partner's projects. But it was only through long research and experimentation that we were able to get the concept of sound, which we have been pursuing for a long time and which fits most fully into the framework of Kennerton products.

Our new driver is a compression type system, i.e., its membrane has an extremely soft suspension and additionally relies on the elasticity of the air volume of the acoustic chamber, represented by the earphone cup.

This is done in order to lower the resonant frequency of the dynamics, and accordingly the depth of reproduced low frequencies. This feature makes the speaker extremely responsive to any slightest change in acoustic design, its volume and filling. In addition, the membrane “warms up” (it enters the nominal mode of operation, gets rid of internal stresses, gets softer in places of suspension bending) for quite a long time – at least 72 hours of work according to the results of our tests. And for a complete “warm-up” it usually takes up to a week of the total time the headphones should work. All this made our engineers work very hard, but everyone who could listen to the headphones sound finally was amazed by the great result.

We were able to achieve high compatibility both with hi-end systems and with low-end devices, while maintaining a consistently high level of sound, limited by the capabilities of the source, rather than the headphones themselves.

For Kennerton Gjallarhorn, we use a steel headband with a minimum of moving parts, which means maximum reliability. Headphone cups made of precious wood are not only beautiful and just pleasant to touch, but also bring warm and natural notes to the sound of the headphones, eliminating the intrusive “plastic” overtones of competitors’ models. Lightweight design, self-adapting to the user’s head and genuine leather ear cushions provide the highest comfort for long-time listening.



Ear cushions are hand-made from soft lambskin from a remote highland region in Northern Caucasus. All spares are genuine Kennerton products and match the quality and craftsmanship that embodies Kennerton.


Soft ear cushions for maximum comfort. The design places driver at optimum distance from ear, improves soundstage/imaging, and musical coherence.

Kennerton Gjallarhorn is a new level in its segment – classic design solutions with the spirit of “old school”, the best natural materials and modern high technologies make this model an outstanding one to be highly appreciated both by audiophiles and professional audio industry.

The kit includes a comfortable eco-leather case for a safe storing and carrying the headphones.

Product Reviews


Kennerton Gjallarhorn GH 40 vs GH 50 JM 

Although both headphone models are similar in weight, the GH 50 definitely feels like a more luxurious wear. On the flip side, the GH 40 has more effective natural sound isolation. The GH 50 is vastly more spacious, producing a much greater sense of distance than the comparatively intimate stage of the GH 40. However, because the GH 40 has more closed feel, the mid-bass is often displays greater in-your-face punch. Perhaps because the GH 50 is a more open headphone, the GH 40 sometimes presents a warmer, and once again, more intimate sound in the mids. Vocals on the GH 40 in the highs sound fleshy and velvety, while the GH 50 delivers more buoyant and delicate feel.
