The essence of music - only headphones harmonia
From Thomas Scharfenberg on August 29, 2025
It's been a while since I wrote a blog about headphones. This wasn't because there weren't any exciting new products in this area—it was simply due to a lack of time on my part.
Time is still lacking, but in this case or rather with this product I cannot help but take the time to introduce it: The ONLY Headphones Harmonia Headphones.
THE ESSENCE OF MUSIC
That's the motto of NUR Headphones, and when you listen to music with the Harmonia for the first time, it becomes clear after just a few bars why. It's all about emotions and—as the name of the headphones suggests—harmony.
But before I go into detail, I'd like to briefly introduce ONLY Headphones. That is, I'll let the designer and company founder Angelo De Mattia prefer to do it yourself:
_________________________________________
My name is Angelo De Mattia. I'm a designer and painter, and I've always loved music as an essence that can guide us to our innermost being.
A few years ago, I developed a deep love for listening through headphones because they accompanied my meditations. It was during one of my moments of relaxation that a strong desire to develop headphones with the features I value so much manifested within me.
Spatiality, definition, deep and captivating bass, natural mids and vocals, and defined highs that never tire. These were the foundations upon which Nur Harmonia was founded.

Unboxing
The result of Angelo's passion for art and music is sitting on my mind right now as I write this blog, and I'm finding it difficult to concentrate on writing. So let's first take a look at what Angelo has to offer clients...
The Harmonia comes in a compact, stylish cardboard box, clean and simple...
The headphones come in a hard carrying case, which also contains cables and other accessories.
In addition to a greeting card from Angelo, the Harmonia comes with a cable, manual and owner's card with serial number.
There is also something very special:
Angelo's patented "Sound Feeling System" - A set of four felt inserts that allow the Harmonia's frequency response to be adjusted to the owner's personal preferences.
The Harmonia is essentially a planar magnetic headphone and one of the best I've ever heard!
State-of-the-art technology for stunning sound
The Harmonia's frame is a complex combination of innovative materials. The outer shell, manufactured using additive manufacturing technology, utilizes nylon powder with 30 percent carbon content, reducing overall weight and thus improving comfort.
Structural rigidity is ensured by the combination of a steel mesh and the robust billet aluminum structure of the planar driver. Carbonylon allows to create complex structures within the enclosure that can absorb sound reflections, making music reproduction particularly precise and captivating.
Sound check
Enough of the introduction - what does the Hamonia sound like and does it really live up to the bold announcements? I tested with the following setups:- Harmonia + Lotoo Mjolnir
- Harmonia + Auris Audio Headonia 300B + Rockna Wavedream DAC/Rockna Wavedream NET
The Auris/Rockna combo is absolutely high-end—it doesn't get any better than this. I'm using it to test how far I can push the Harmonia.
I plan to test the Harmonia with a DAP (Digital Audio Player) soon to see if a small, compact device can make the Harmonia "sing", because the Harmonia seems to be in contrast to other Planars (hello Susvara👋) to be very frugal.
Total harmony
I won't beat around the bush: Yes, the Harmonia more than deserves its name, because that's exactly what it is: harmonious—headphones for hours of relaxing music listening!
Resolution and detail are by no means neglected. Nothing is "rounded off" or glossed over; everything is there, as it should be.
Harmonia + Lotoo Mjölnir
What immediately strikes you is a wonderful naturalness with plenty of breathing room. Female and male voices are intense and sonorous, and guitar strings resonate realistically.
The channel separation is truly uncanny, and the spatial representation is one of the best I've ever heard from a headphone. The protagonists in the composition are clearly identifiable and distinguishable, yet all the participants play together as one—that's how it should be!
Somehow, Angelo De Mattia has managed to construct a planar headphone that has all the advantages of a typical planar headphone but none of the disadvantages. At least not as far as I can tell.
What I'm saying is, this thing not only delivers great vocals, tons of detail, and a three-dimensional soundstage, but also a wonderfully crisp, deep, satisfying bass that many other Planar speakers lack. I haven't even experimented with the "Sound Feeling System" yet.
Oh yes, I listened to a variety of music styles while testing the Harmonia and would say that it handles pretty much all of them very well – a true all-rounder.
Harmonia + Auris Audio Headonia 300B + Rockna Wavedream DAC/Rockna Wavedream NET
With this absolute high-end combination, the Harmonia goes above and beyond and even poses a threat to much more expensive headphones! 🙌🤩
The stage becomes even bigger, voices more intimate and the bass has a pressure that makes your hair stand on end - at least that's how it was for me.
In short: Everything that the Harmonia already did well with the excellent Mjölnir, it does even better in this monstrous chain, which means nothing other than that the NUR Harmonia continues to scale with better sources and thus offers a lot of potential for the future, should the interested buyer upgrade their amplifier/DAC.
Conclusion
The ONLY Headphones Harmonia is an amazing headphone that, while not cheap, is definitely good value for money, as it performs way above its price range - depending on the connected source.
Headphones that invite you to simply enjoy the music and thus more than live up to their name!
The NUR Harmonia can be tested at home or in our showroom.
