Gjallarhorn GH50 JM Edition Mk2 Stabilized Turquoise Karelian Birch Mini XLR V2
This one is in stock - as shown! Usuallywhen custom ordering could take 3-10 weeks after order.
Utilizing Patent pending multilayer JM Proprietary Fractal Fiberglass Mesh Technology (TM).
Horn-type headphones are musicality, integrity of perception, overall harmony, natural sound and the ability to completely capture the listener.
Extremely hard Janka hardness rating of 1,450 lbf will provide excellent sound and highly desirable sound pitch.
JM Edition is an acoustic modification of Gjallarhorn headphones, which was made by John Massaria
, 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. You can read in depth about the modifiacion from the first hand, from the author himself.The main differences touched the bullhorn form and change of phase inverter. It did significantly changed the accent of the sound of the headphones without dropping any quality at all.We named the model after the author, JM Edition.
NOTE: Price includes headphone, mods and shipping within the Contiguous US.

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.

RETURN & REFUND POLICY
I stand 100% behind my mods and how they stack up against the original unmodded sound - and I test each and every single mod before we put our seal on the right ear cup ensuring it met our requirements for sound and its appropriate mod. If a user is not 100% satisfied with the modded sound they can return the item by shipping it back to have us retune it so it is more custom to what the user wants (add bass or reduce higher frequencies) or we can return the item back to original tuning. We guarantee our mods are free from defects or issues for a period of one year for all purchases. As far as comfort on the head - we get it not evey band is going to meet your needs- we offer headband upgrades for our customers- just ship the headphone back to us and we accommodate your requests of changing the mod or headband. The headband does cost us time and money- E-mail us at massriaj@yahoo.com for more details or specific questions before you buy. PEACE OF MIND: If a product fails for an original owner- we stand behind it for an entire year and will repair or replace if need be. This does not cover abuse like dropping it or misuse. Overblown drivers from excessive amplitude will not be covered. We want our customers to be happy customers! Now and in the future.
