Don't Believe The Hype. Don't Let Them Fool You!

Today there are many claims being made about headphones. Many brands offer expensive in-ear solutions with multiple drivers. Did you know those multiple drivers are actually very limited?

While you pay a lot of money for so-called superior sound quality, you are actually paying for technology that is masking its own shortcomings.

All those great stories you read are simply not true. With multiple drivers you get unavoidable frequency overlaps. The more drivers, the more troubles.

This is caused by a phenomena called crossover distortion.
It is in all those expensive earbuds.
And you pay for it. Big time!

That is horrible, right? It is simply not fair.

What if we tell you that in nature all sounds come from single sources. Therefore the most natural sound comes from one single driver.

It completely blocks the possibility of interference and distortion. Therewith it completely eliminates phase distortion.

Something you consider as normal in those expensive multi-driver headphones you own. It is time to change the way you think about audio.

Let us show you what we’ve got to offer!

One single full range driver is as a dream come true for all audio professionals and audiophiles!

We’ve completely stripped the wired in-ear headphone. And improved what is absolutely relevant for you. Now you can experience sound as it intended to be. Not only because of our unparalleled technology but mainly because of our unmatched price.

Our revolutionary single driver technology is a game-changer for professional creators and music lovers. That is why we sold 200.000 units in 18 months in South Korea. That is how our wired earbuds became the #1 reference in-ear headphone for K-Pop fans & artists with a 70% market share.

The secret is in one full range single driver technology.

#1 headphone chosen by 

K-POP fans & artists

This is why direm E3 became the market leader in South-Korea and sold 200.000 units!

HARMAN Wired Earphone Preference Prediction Score

Listen inc. Sound Check V.17 - Harman Predictive Model for In-Ear Headphones

Harman is the leading company behind brands such as JBL, AKG, Infinity, HarmanKardon and Bowers & Wilkins. In other words, they know what high quality audio is all about. Harman’s Target Score is seen as the most important reference for headphones.

This measurement was performed using Audio Precision’s APX555 and GRAS’s international standard ear simulators. Depending on the depth of wearing and type of ear tip, the degree of matching may vary.

Actually, the Harman score is excellent for hifi. In the first test we scored 91%. We then refined the direm E3 with the Genelec 8050B studio monitors as a reference in the studio.

That is why they sound like professional monitor speakers.
We deliver you the best of both worlds.

“I thought it was impossible to achieve such a high score with a single driver.”

– Dr. Sean Olive, Senior Research Fellow of Harman International

Dr. Sean Olive, Senior Research Fellow of Harman International (JBL) and considered the world’s foremost acoustics expert, praised the direm E3 headphones. The direm E3 received the highest score in the world, even compared to the headphones developed by HARMAN itself.

“The best parts make the best sound.”

Dr. Sinlyul Lee is the head of direm E3 development and the leading inventor behind the SF driver. In addition, he is the head of the audio equipment division in the Acoustical Society of Korea and the Korean representative for International Electrotechnical Commission (IEC) Audio Division.

He serves as a sound technology advisor to Samsung, LG and Hyundai and provides technical advice to world-class R&D equipment manufacturers. His work for direm E3 and especially the SF-Driver deliver an unmatched listening experience with a full dedication on realistic sound reproduction.

“Sound quality is the most important design criteria in wired headphones.“

- Dr. Sinlyul Lee, Ph.D. Sound Engineering, National University in Korea.


Let us share our deepest secrets with you!

With direm E3 we combine advanced technology with the best parts and components available. As a result, we deliver an unparalleled listening experience. What is even more surprising is the unmatched price.

All components that make up the 3rd generation SF-DRIVER™ and the Automatic Pressure Control System (APAS) are manufactured with extremely high precision and reliability.

Let us tell you how this will benefit you!

3. Generation SF-DRIVER™ (made in Korea)

The 3rd generation SF-DRIVER™ combines the advantages of balanced armature (BA) drivers and dynamic drivers (DD). It is specially developed by Dr. Sinlyuyl Lee in Korea and is the new standard for ultra-high quality drivers.

The toroidal neodymium magnet applied to the dynamic driver provides a stronger driving force than your regular BA driver, as known from those expensive earbuds. Our 3rd gen SF-DRIVER™ provides full control over the non-metallic triple-layer diaphragms.

The 3rd generation SF-DRIVER™ in the direm E3 is applied through the improvement of the ultra-precision acoustic damper and magnetic structure, resulting in higher Harman target matching and lower distortion.

Automatic Pressure Control System (APAS)

The self-developed Automatic Pressure Adjusting System (APAS) removes the discomfort by removing the pressure generated when using the earphone out of the ear, while at the same time trapping the original sound inside the earphone and blocking the external unwanted noise.

The world’s first use of this technology was in high-precision acoustic measurement equipment. It is now applied to the direm E3 earphones so that the eardrum is not pressed or cannot hear the diaphragm distortion.

In addition, APAS is automatically adjusted to atmospheric pressure, so the pressure does not cause the eardrum to be pulled or pushed. Therefore, it can be used in aircraft, in the mountains, on high-rise elevators, etc.

High Precision Acoustic Damper 

(made in Italy)

For ultra-high sound reproduction, the direm E3 uses the highest precision acoustic damper from SAATI in Italy, the world’s leading damper manufacturer.

The five (5) nanometer-precise acoustic dampers not only achieve ultra-high sound quality but also helps to reduce acoustic tolerance between components.

The non-metallic triple layer diaphragm was developed using the latest acoustic measurement and analysis equipment. It fundamentally eliminates split vibration and enables ultra-high quality audio reproduction.

Passive Noise Cancellation

With our APAS technology, direm E3 provides greater sound isolation than active noise-canceling earphones. This is measured using the GRAS international standard ear simulator and pink noise source. The sound isolation rate may vary depending on the depth of the ear and the size of the ear tip.

Since the direm E3 is manufactured based on a completely enclosed design, it provides higher sound isolation than normal Feed Forward (FF) active noise-canceling earphones. They provide -40 dB at high frequencies and -20 dB at low frequencies so that you can enjoy a safe and comfortable listening experience even in a noisy space.

What’s Even More Surprising Is The Price!

With the direm E3 you get unparalleled technology against an unmatched price.
Together with our ultra high-fidelity 3rd generation SF-Driver™ you are now able to experience sound as it should be.

Our full range single driver enables smooth sound reproduction from 10 Hz to 35kHz. It reduces the distortion rate and totally eliminates phase distortion.

This results in a more consistent frequency response compared to its competitors, as proven by the highest Harman score ever measured for wired earbuds.

Its excellence was recognized by 200.000 direm E3 headphone users in South-Korea.

Due to its natural sound, it is a safe choice for young kids and people who protect their ears against high-level outputs.

Direm E3 is the #1 wired in-ear headphone for high-quality audio playback and monitoring. Therewith it is highly recommended for people that demand high-quality audio such as for ASMR, audiobooks, podcasts, music, and gaming.

Also, it comes with a high-performance microphone and nano-coated waterproof cable. Now you can get the most honest, natural sound against an entry-level price.

You will get a high-quality in-ear reference headphone that easily outperformance expensive professional headphones and wireless earpods worth over 500€.

All those gadgets and multi-band drivers they try to sell you, are just to fool you. That is why we focus completely on delivering you the best sound reproduction possible.

Our present for you: you will get a free carbon case + free shipping in every EU country until New Year by ordering direm E3 now.
