Another great review. This one in Positive feedback at:  https://positive-feedback.com/reviews/hardware-reviews/lsa-hp-1-headphones/

They sum with:

"Walter's assault on prices and HiFi norms is becoming more aggressive. He and the small team at Underwood HiFi have a good ear. They are identifying great sounding pieces of equipment and finding ways to deliver them at a fraction of the expected retail price."

"The LSA HP-1 is now my go to under $2000 headphone recommendation. Its performance is peerless at its price point, and its technical performance puts it within spitting distance of some of the best headphones in the world, regardless of price."

"Thank you Walter, these are a gift to anyone who loves HiFi regardless of their ability to spend."



 
See the killer new review in headphone.guru. They say:
"The LSA HP-1 is a spectacular planar design that Walter Liederman had the insight to have developed and made under his own Living Sounds Audio brand."

"Once in a long while, a product comes into the listening room that takes hold of me and does not let go. The HP-1 is such a product and has been in constant use since its arrival."

"If you are looking for a well-balanced sound you need to hear how good the HP-1 sounds. The fact that it is offered for so little money makes this one of the best values in personal audio. Dynamics and musicality are what the LSA HP-1 is all about and one of the best headphones I have heard and worthy of reference status. Highly recommended."


Our first headphone, LSA HP-1 is a typical LSA/Underwood product. It offers superb value coupled with great sonics. We searched the world for a quality phone that could offer at a great price to performance deal and are very excited to present the HP-1. They are a version of a $2200.00 pair of marvelous Kennerton Odin planar phones, made in Russia. However, with our modifications they sould more lie the $2800.00 Thekk.

From the owner of Kennerton:

The difference of HP-1 and Odin:  Actually, HP-1 have more similarities with Thekk than with Odin. Firstly, they have a very similar construction, the same lightned cups of complex form, which negate the emetging in-cup resonances. While Odin has massive cups of simpler form. Secondly, HP-1 and Thekk has light grills of aluminium alloy covered with anti-resonance coating. Notably, the HP-1 grills maximally open, it reminds of a spider web, for more detailed and "airy" sound with wide scene. Odin has grills of very heavy zink alloy for bassy and warm sound.

Thirdly, HP-1 the tuning is completely different due to different acoustic filters.

In short, in common they have only the driver. Nothing more. With Thekk those have more similarities.

We loved their sonics and had them tool our custom aluminum back plates that lower weight by 150 grams over the $2200.00 version. They weigh only 485 grams. We sell them with our Low Overhead Internet Direct model at only $1399.00. Compare them to any under $3000.00 competition that we have heard.

The HP-1 offers the unique sound so much loved by planar headphones enthusiasts! Stunning detail and clarity combined with powerful and beautifully controlled bass.

Here is a customer feedback:

"Good morning Walter!
Just wanted to let you know that I received the package last week. The LSA-1 headphones were stunning right out of the box! I heard details out of my CD’s that I didn’t even know were there!
At this point I have 6 hours in the breakin period. I log numerically the CD I listen to so when I get to 100 I’ll know I’m there. But I have to say that after the 6 hours I am almost hearing a 3D sound. Sometimes I would pull the headphones off because the sound felt like it was coming from ‘outside’ the headphone! Thank you for bringing an incredible headphone (along with an unbelievable price) to the market."

Please note that our phone is significantly lighter and selling for 40% less than the Odin in the reviews above. It also sounds better as it uses the new lighter current upgraded Odin 4 driver. We think a great value.

The HP-1 uses only  high-quality materials – steel, aluminum, genuine leather and precious wood.
 

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. The HP-1 is 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 25-year old planar magnetic technology hasn’t evolved with time.

Our supplier got to the drawing board and started to make their own drivers from scratch. One of their core goals was to minimize internal structure resonances and optimize sound wave patterns, in order to create clear, low-distortion sound. To achieve this, they 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.

The drivers are solely designed and produced in Russia, which involves a facility that also works 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.
  • The driver allows greater sensitivity, thanks to its powerful magnets and low-mass diaphragm. It can therefore be easily driven by portable devices.

We aimed for reliability and durability along with great sound.

LSA HP-2 Ultra
List $1200.00
Our Internet Direct price: $799.00

The new HP-2 Ultra is our breakthrough in an affordable under $1000.00 headphone. It is our version of the Kennerton Gjallarhorn. This new $1200.00 Kennerton phone uses a superb new horn loaded 40 mm driver with a bio-cellulose and paper membrane with a graphene coating. The original Kennerton Magni received great reviews and our new upgraded HP-2 Ultra version is a clear step up.

See William Murdock's, from The headphone Experience, first video pre review at: 
https://www.youtube.com/watch?v=xVtXAQXdgKg&pbjreload=101

The new driver is a compression design, 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 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 requires 75-100 hours of play for full break in. As it plays the suspension softens and gives you the corect bass output. Once broken in the results are superb and make the LP-2 Ultra the best under $1000.00 phone that we have ever heard. The HP-2 Ultra headphone is an easy 33-ohm load and 105dB efficient.

In the first print review Headphone. guru said:

"My first impression was of extreme speed for a dynamic headphone and a neutral tonal balance with a very live bottom end. The timbre of the instruments was excellent and the clarity laudable."
"
Vocals had a natural in-room feel despite the large hall soundstage, as did the acoustic guitars. Paramount over all was the dynamic range, which as one would expect was enhanced by the horn design of the HP-2 Ultra."
"
My first impression was that for the first time I could hear the spittle rattle in Mile’s trumpet for what it was. Though the upright bass cello was a bit more present than one would expect, the sweetness of the horns was magical, and the playback of this track was probably the richest and most musical I have ever heard it."
"
the HP-2 Ultra turned out to be one of the best sounding dynamic headphones I have heard. Fast and dynamic, though the HP-2 is a little hot on the bottom end they are neither boomy nor muffled, as it happens, their clarity of midrange is their most notable characteristic. They are what I think of as a fun headphone, they work well with all forms of music from House to Classical and I would recommend them to fans of any style and genre of music, not something I can often say."
"
They are a headphone fan’s headphone. They offer a vast soundstage with laser-etched imaging" "The build quality is top-flight while the design is simple and elegant, and communicates the look and feel of a much more expensive product."

The LP-2 Ultra uses a steel headband with a minimum of moving parts, which means maximum reliability. The headphone cups are made of real wood that 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.

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

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 a 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.

Our HP-2 Ultra is the same as the
Gjallarhorn with our cosmetic changes. Sonics are exactly the same.
