Gjallarhorn JM Edition
“When the sound completely captures you”
Kennerton Gjallarhorn – the first in the world horn-loaded headphones!
Horn-type headphones are musicality, integrity of perception, overall harmony, natural sound and the ability to completely capture the listener.
We named the model after the author, JM Edition.

Kennerton Gjallarhorn “JM Edition” – A triumph for innovation, a victory of concept design.
– Outstanding timbre and dynamism rendition.
– Accuracy: notes stop and start when they should, which creates an incredibly realistic sound, specially in live recordings.
– Soundstage and depth unheard of in closed-back cans. Music meant to be played in big theaters or audiences in general is unbeatable (classical, some jazz recordings, soundtracks, etc…).
– Perfect balance between detail and musicality. Instrument separation is unreal, yet it never ends up being too analytical.
– Vocals: Quoting John Massaria “liquid, intimate when recordings call for it, wet when recordings reveal such wetness”. And throwing in my two cents: explosive & vibrant when recordings call for it as well, such as in soprano and operatic voices in general.
– Unique, non fatiguing, immersive, addictive sound signature.
– Comfortable for long periods, (upgraded soft ear pads made of lambskin).
– Aesthetically gorgeous: heirloom wood finish, hand-crafted, laser engraved logo.
The most important advantage of horn headphones is the ability to develop a 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.
Horn-type headphones are musicality, integrity of perception, overall harmony, natural sound and the ability to completely capture the listener.
HIGH PERFORMING GRAPHENE MEMBRANES
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 is exceeding 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, 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 partners 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.
HIGH QUALITY 2 METERS OFC CABLE
WITH 3.5 MM RHODIUM PLATED CONNECTORS AND GOLD PLATED 6.3 TRS CONNECTOR.
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.
LAMBSKIN LEATHER CUSHIONS
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.
The Gjallarhorn is one of the more unusual headphones in the high-end space, offering a darker tuning thanks to an attenuated treble section. In stark contrast to its smooth highs, the Gjallarhorn presents one of the more-captivating and potent bass sections in the contemporary space. Thankfully, the company avoids the pitfalls of an overly-bloated bass section by tweaking the low-end to provide just the right amount of bass. Couple that with a world-beating presentation, replete with gobs of texture, and you’ve got one heck of an enjoyable basshead headphone.
It’s not all bass, bass, bass, though, as the Gjallarhorn offers a solid rendition of a lush and weighty vocal response. With decent-to-good levels of technical finesse, the Kennerton headphone produces instruments and voices in a well-defined stage.
The Gjallarhorn may not be a horn-shaped 2-channel speaker, but it brings the joys of listening to one into a distilled, portable, and personal audio space. Try it, you may just fall in love with Heimdallr’s horn. This is certainly a basshead headphone that’s crafted well.
The GH 50 JM is quite the experience. If Kennerton wasn’t a name you originally recognized, it should mean something now. This headphone is so carefully constructed in its build, and that’s completely reflected in the sound signature. It might take some major break-in to get used to the feeling of the GH 50, but once that’s done, you should experience one of the lightest and most comfortable headphones available today. For the price, it’s worth looking into, especially if you’re itching for an audiophile headphone with some personality.
