PLANAR MAGNETIC CLOSED BACK OVER-EAR HEADPHONES
HIGH-FIDELITY HEADPHONES FOR PROFESSIONALS AND AUDIOPHILES
Kennerton Rognir is the first planar-magnetic closed-type headphones of our company, which sound on a par with the best open-type models!
For a very long time we could not make a decision to take this step – to release planar-magnetic headphones of a closed type.
We’ve done a lot of experiments and created a lot of prototypes. But we still did not dare to release this model. Why? Because we didn’t want our new model, which we put so much work and efforts into, to be talked about in the same way that many audiophiles talk about the vast majority of headphones of this type. Here is one example:
“The day I discovered the sound of headphones in an open design I realized that I would never return to a closed design, because everything that suited me in them, in practice, turned out to be a negligible compromise! Planars have the right to exist only in an open performance!”
Isn’t that a very familiar mood of the review?
We wanted to get closed-type planar headphones, which would not be a compromise option for replacing open planars, but a wholesome alternative to them!
And after almost 2 years of efforts, we are ready to show this model to you!

WHAT’S IN THE BOX
PLANAR MAGNETIC HEADPHONES
Kennerton Rognir is the first planar-magnetic closed-type headphones of our company, which sound on a par with the best open-type models!
CUSTOM LITZ CABLE 2 X MINI-XLR
In order to achieve the highest possible sound level, each pair of Rognir headphones is equipped with a custom hand-woven cable specially designed for it from a limited stock of vintage litzendrat of a special series produced in the 40s of the 20th century. Never before has Rognir sounded as expressive and transparent as in the Novel version!
You can now choose whether you want standard 6.3 mm or 4-Pin Balanced XLR!
COMFORTABLE ECO-LEATHER CASE
A case is designed to protect and make your headphones easy to transport.
Keep your headphones safe from damage and easily portable with the Full Sized Headphone Case.
It gives you durable protection. The shell and the inside has a soft lining that keeps your headphones safe from scratching and damage.
WHY PLANAR MAGNETIC?
In our eyes, we see the perfect headphone as a cross-breed of the dynamic and electrostatic technologies combined into one. Whereby taking the airy and extremely detailed sound of an electrostatic driver, and combining it with the power and impact of a dynamic transducers. This enables us to achieve a sound that’s both natural and engaging.
When we looked at the market to see what our competitors have been producing in the last couple of years, we were surprised to find that the most recent planar magnetic headphones all had the same design and thus also shared the same flaws. This indicated to us that the 35-year old planar magnetic technology hasn’t evolved with time.
We got to the drawing board and started to make our own drivers from scratch. One of our core goals was to minimize internal structure resonances and optimize sound wave patterns, in order to create a clear, low-distortion sound frequency. To achieve this, we created several patent-pending core innovations. Its magnetic structure is designed to eliminate both unwanted resonances, and unify magnetic field distribution over the total frequency range.
SO WE STARTED MAKING OUR OWN DRIVER FROM SCRATCH.
Our drivers are solely designed and produced in Russia, which involves a facility that also work for the aerospace and military industries, which ensures the highest quality and durability of our headphones.
- A new 80mm planar-magnetic driver, with every aspect of this technology being implemented, such as phase coherence, flat impedance and a low-mass diaphragm.
- Multi-layer 10µm polyimide film diaphragm, tested to have the highest reliability and longevity in the most extreme environmental conditions.
- FEM-Optimized Magnet System with 10 neodymium magnets arranged in symmetric push-pull configuration.
- Unique semicircular bar magnets.
- A semicircular form therefore has many advantages over the ordinary rectangular shaped bar magnets: It gives a more uniform magnetic field, greatly reduces internal resonances and produces an optimal sound.
- Our driver allows greater sensitivity, thanks to its powerful magnets and low-mass diaphragm. It can therefore be easily driven by portable devices.
- The driver is made of super strong and light material – Carbon.
We aim for reliability and durability, and so used simple but functional construction. Aerospace grade aluminum and steel used. Quality wooden ear cups.
THE MANUFACTURING PROCESS OF STANDARD WOODEN CUPS
1. All wood types used for making the headphones’ assembly and cups always undergo multiple different processes. We use drying and coating methods which have antibacterial substances making the cups pleasant to look at and resistant against environmental factors.
2. Our wooden cups are made by a specific in-house developed procedure. The wood types and geometry of acoustic design, influences the sound and we therefore take this into account when producing and designing our cups.
3. Cups are manufactured by a 3D model on a computer controlled by a precision machine; the machines have extreme processing quality and geometric shape repeatability.
4. After the milling operation, the cups are sanded and polished by hand.
5. After sanding, wood is coated by using special oils to protect it from humidity and prevent it from deteriorating.
6. After that, the work pieces are processed with microwaves for several minutes in order for the oils on the cups to avoid deterioration.
7. After that, the cups are covered by hot bee-wax and dried in a special drying chamber for about 1.5 hours. Temperatures may reach 74 degrees centigrade (where it varies from 60 to 74 degrees centigrade depending on the type of wood).
8. Drying is followed by the cups being cooled at room temperature for at least 6 hours. The work piece is ground for the second time, hot wax is again applied; which is again followed by drying the cups at the same temperature 74 degrees, for about 8 hours.
9. The closing stage of the work includes thorough polishing of the cup, laser engraving of the logo and other elements as per the design. In some cases, patina forming treatment is applied for a decorative finish that makes the surface look perfect.
Note: Due to specific nature of every piece of wood each pair of wood cups can not correspond precisely to the photo on the website.
