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 planar
phones, made in Russia, the Odin, by Kennerton. We loved their sonics and had them tool a
custom aluminum back plate that lowers weight by 90 grams, to 540 grams, as well as doing custom lacquer wood frames for us, over their
standard $2200.00 version. We are selling them with our Low Overhead Internet Direct model at only $1399.00. Save an extra $100.00 during this intro sale. Compare them to any $2000-$2500.00 competition that we have heard.
offers the unique sound so much loved by planar headphones enthusiasts!
Stunning detail and clarity combined with powerful and beautifully
controlled bass. They lean to the warmer side of neutral versus the hyper detail of some other phones. They are great for long listening sessions
The HP-1 uses only high-quality materials – steel, aluminum, genuine leather and precious wood.

WHY PLANAR MAGNETIC?
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.
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.
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 THEY STARTED MAKING THEIR OWN DRIVER FROM SCRATCH.
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.
new 80mm planar-magnetic driver, with every aspect of this technology
being implemented, such as phase coherence, flat impedance and a
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.
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.
driver allows greater sensitivity, thanks to its powerful magnets and
low-mass diaphragm. It can therefore be easily driven by portable
We aimed for reliability and durability along with great sound at an internet direct with no dealer profit cost.
