●Amplify sound source up to 32bit/384kHz. Reproduces sound quality six times that of a CD.

●Reinforced coated pure copper cable minimizes noise generation.

●You can enjoy the high-resolution experience not only on Android smartphones, but also on PCs and mobile games.

Many people enjoy listening to music on their smartphones while commuting to work or school.

Recently, there are more and more services that allow you to listen to your favorite music on a monthly basis, so music on your smartphone is becoming more and more familiar.

However, smartphones are originally communication items.

The sound quality is far from portable audio players.

On smartphones, which have limited data capacity, the sound source is rewritten and compressed into data called coding, and then digitally processed and played back, so the sound quality is actually inferior to that of a CD.

On the other hand, portable audio players dedicated to music are mainly high-resolution sound sources with overwhelming sound reproduction.

However, high-resolution has a large amount of data, and smartphones with multi-functions can quickly run out of data.

Although there are smartphones that support high resolution, the reality is that they are expensive and out of reach. On the other hand, portable audio players dedicated to music mainly use high-resolution sound sources with overwhelming sound reproduction.

However, high-resolution has a large amount of data, and smartphones with multi-functions can quickly run out of data.

Although there are smartphones that support high resolution, the reality is that they are expensive and out of reach.

This [DAC Earphone Amplifier Pro] is the world's smallest class digital amplifier that amplifies the sound source data of the smartphone to a high-resolution sound source with its own technology and reproduces overwhelmingly realistic sound quality.

Easy to operate, just attach it between your smartphone and earphones.

There is no difficult operation.

Of course, cheap smartphones or cheap earphones that came with your smartphone are fine.

* Not all iPhone models are supported.

By simply attaching the [DAC Earphone Amplifier Pro], you can easily experience the ultimate sound that rivals the master recording sound quality of a studio.

No special preparations or difficult operations are required to set up the [DAC Earphone Amplifier Pro].

Simply connect the [DAC Earphone Amplifier Pro] between your smartphone or other digital device and wire-type earphones, and you can immediately experience high-resolution, immersive sound.

The volume can also be adjusted with the volume button on the smartphone or earphone side, so you can use it as if you were listening to music on your smartphone.

Power is supplied from the smartphone, so charging is not required.

So even those who are not good at machines can use it easily.

The [DAC Earphone Amplifier Pro] is 10.3cm long and weighs 12g, so it won't get in the way even if you attach it to a wire earphone.

Of course, it is a super compact size that fits perfectly in your pocket.

Don't worry about your phone.

Smartphones and computers have a built-in machine called a sound card equipped with a DAC (digital-to-analog converter) that converts digital sound sources into analog signals and transmits them to speakers.

Commercial PCs and smartphones often use low-performance sound cards, and even if the sound source is good, the sound quality is disappointing at the stage of transmitting analog signals to earphones.

[DAC Earphone Amplifier Pro] has an ultra-compact and high-performance DAC decoding chip built into the tip.

As one of the world's smallest class external sound cards, it functions as an alternative to smartphones and PC sound cards.

Therefore, the high-performance microchip of the [DAC Earphone Amplifier Pro] digitally processes the sound source data on the smartphone or PC side as a high-resolution sound source and transmits it to the speaker on the earphone side as an analog signal.

So you can easily experience high-resolution sound quality even with a cheap smartphone by using [DAC Earphone Amplifier Pro].

When digitizing a sound source, the quantization (bit) of the sound and the frequency (Hz) representing the pitch of the sound are digitized.

The wavelengths of natural sounds that we normally hear are very similar to waves, but in data conversion, the waves are divided into small pieces and digitized.

However, if the natural sound is converted into data as it is, the data volume will be enormous, so the deep bass and high frequencies that cannot be recognized by hearing are thinned out and digitized.

By the way, CDs are 16bit/44.1kHz, which means that one second of sound is fragmented into 44100 times and converted into 16bit data.

The reason why music enthusiasts say that CDs lack the sense of reality compared to analog records is that they cannot reproduce the deep bass and high frequencies that people feel with their bodies.

High resolution can record a huge amount of sound source data, so it can reproduce sound with a sense of realism.

On the other hand, the amount of data in sound sources used in smartphones is smaller than that of CDs, and when played back as is, the sound quality is disappointing, lower than that of CDs.

[DAC Earphone Amplifier Pro] restores the thinned data with a high-performance DAC decoding chip using its own PCM (Pulse Code Modulation) and amplifies it to a maximum of 32bit/384kHz.

Rebuild as a high resolution class sound source.

This is equivalent to 6 times the amount of data of the sound quality of a CD, and the sound is as close to natural sound as possible.

That's why even streaming sound sources with a small amount of data can be reproduced with dynamic sound quality just like a live performance.

You can enjoy clear and powerful HiFi sound.

Then, how much difference in sound quality is there before and after attaching [DAC Earphone Amplifier Pro]?

Mr. Masayoshi Oishi (Kemono Friends, Daiya no A), Mr. Nakayama (Professional Musician & Producer Review & BGM Production), Mr. Kojima (Recording Engineer Professional Magazine Review) actually experienced it.

I tried using the "pro spec" on my iPad Pro, but sounds that I couldn't hear before, such as the breath of vocals and the noises of electric guitars, were expressed with incredible resolution. I was surprised.

In addition to the extension of the treble, I was grateful that the bass, which would have been boomy and broken in a conventional listening environment, could be heard clearly.

I thought it would be a big advantage in listening to music with a wide frequency range, which is trending recently. The "Normal spec" is also lightweight and stylish, which makes it easy to handle.

I'm really excited to think that 32bit/384kHz specs like two generations ago are realized in such an ultra-compact driver chip. The future was already here.

I was blown away when I connected this DAC earphone amp between my usual earphone and my PC to make a sound! What's inside such a small part?

I never thought I could hear such an exciting sound coming out of my usual earphones. I didn't expect it at that time, and I couldn't help but scream.

In my line of work, I make music in a variety of environments, and I perform in a variety of environments as well.

"I want to listen to music with a cool sound!"

"I want to get a situation that is as close to my usual work environment as possible in a compact and easy way."

This feeling is for those who aspire to music. Also, those who want to enjoy music casually with good sound. I believe that all music fans have the same feeling, and this earphone amplifier fulfills that thought.

Please get it and experience this excitement.

The usual earphones will be reborn.

And this time, I compared this earphone amplifier at the site where I usually make it.

■Normal Spec

This naturally expands the overall volume feeling without difficulty.

It sounds like when you turn the audio volume knob to the right, it doesn't smell like compression, and the sound image is very natural.

I was surprised that the sound quality was so good.

■ Pro Spec

This is completely different from the standard, and the lows are comfortably raised, and the highs are extended to create a sense of space and depth. I could feel it.

However, there is no peculiarity of compression, and it is reborn as a very natural and exciting sound.

I think this will shine more in EDM and electro-sounding music.

Both are Hi-Fi, high-resolution, delicate, clear, and powerful sound.

The earphones you usually use will be reborn.

I feel that the sound environment through the audio interface at home has something in common with the NH1, so I work with the NH1 in my bag!

Try it! it's recommended!

I usually listen to sound in the studio, but listening to music on a consumer device was just a reference.

The first thing that surprised me when I heard this DAC headphone amplifier was that I was able to feel the joy of music again. I think that the clear and solid sound image is at a level that can be used on site.

Usually, when I listen to music on my iPad, etc., I often listen to it with earphones via Bluetooth for convenience, but this product reminded me of the importance of listening to sound with solid decoding on a wired connection. is.

By supporting up to high resolution with a compact body, it is also compatible with listening to music with high resolution compatible apps such as Amazon Music HD, so the intention of the creator is firmly preserved in what is delivered with good sound. I think this product is wonderful because it can be accepted and can be easily carried around.

I think there are many people who have become so-called "mp3 ears" (ears that have become accustomed to compressed sound sources). I would like you to experience the "sound" that the artist originally wanted to convey.

Cable-type earphones use copper wire inside to send electrical signals to the speaker, but copper wire with low purity creates resistance and interferes with the speaker, generating noise. can not be enjoyed satisfactorily.

The [DAC Earphone Amplifier Pro] cable uses pure OCC (single-crystal high-purity oxygen-free copper) used in high-end audio equipment.

This is pure copper with crystal lengths of up to 100m and boasts a very high conductivity because there is no room for impurities.

Therefore, almost no noise is generated with a cable using OCC, and you can enjoy high-resolution sound sources to your heart's content.

In addition, since OCC is vulnerable to disconnection, [DAC Earphone Amplifier Pro] is reinforced with transparent resin.

You can appreciate the beautiful metallic appearance of pure copper, and it is an irresistible gem for gadget enthusiasts.

In addition, the USB-TypeC plug part is coated with zinc, making it extremely smooth to insert into the socket.

Since it has received TID certification from the USB Association, it boasts durability that will not break even if it is inserted and removed more than 10,000 times.

[DAC Earphone Amplifier Pro] uses high-quality materials that are particular about not only electronic parts but also all parts.

For that reason, if you have an Android smartphone with USB-TypeC as standard equipment, you can convert the game sound source to a high-resolution sound source in one shot.

You can enjoy powerful play with overwhelming reproducibility of hitting sounds and explosion sounds in the game.

In addition, if you use a commercially available USB-TypeC/Lightning conversion adapter, the sound source of the Apple and Mac series, which sells high-quality video and music, will be more three-dimensional and realistic.

It can also be connected to an earphone microphone, so you can clearly reproduce the sound quality of online conferences such as ZOOM.

Of course, the OS on the device side is irrelevant because it only converts the audio data into a high-resolution sound source.

You can experience high-resolution sound sources on a wide range of digital devices such as Android, Apple, and Windows.

Most smartphones can play music. However, compared to the sound source format without data loss, most of the DAC decoders installed in smartphones are integrated, and the decoding function is weak, so the sound quality is greatly degraded.

The general listening experience is lacking, and it has not been able to fully meet the needs of people who want good sound on their smartphones.

Currently, most smartphones, such as Samsung Galaxy Note 10/S20/S20+/Apple iPad Pro/Mac book, have only one Type-C interface and only support digital signal output. Therefore, when using wired earphones, it is necessary to equip them with a built-in DAC amplifier.

Nillkin's research and development department thoroughly pursues sound quality and has developed a decoded earphone amplifier that can fully satisfy customer needs by decoding digital signals. 32bit/384kHz high performance DAC provides HiFi level audio experience. (This product mainly supports smartphones with Type-C port.)

Nillkin continues to evolve its product functions, adhering to the concept of "discovering innovation and changing lifestyles." In the development process, the sound quality was adjusted by a technical team from Sony, which repeatedly tuned, auditioned, and readjusted the sound quality data until HiFi-level sound quality was achieved. After perfecting uncompromising sound quality, we conduct marketing for the first time, delivering high-quality products to customers around the world.

Nillkin is an electronics brand founded in 2009 in Shenzhen, China, specializing in innovative products, industrial design, technology development, production, marketing and sales.

Currently, we are mainly developing products for general users such as Bluetooth speakers, TWS earphones, rechargeable batteries, smartphone cases.
