【Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device’s requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.
[About clocks that synchronize time via radio waves]
The function of clocks that synchronize time via radio waves only works in the Japanese area. Please be careful.
A new approach to audiophile headphones The HarmonicDyne Black Hole features an entirely new approach to audiophile headphone design. The two main focuses of this project are: 1) Hi-Fi sound quality and 2) Ergonomic fit. Black Hole offers a completely new audiophile sound quality, delivering immersive and engaging sound while being ultra-comfortable and lightweight.
The Black Hole features a second generation large 50mm composite carbon fiber biofilm diaphragm arranged in an inert sandwich structure. An evolution from our last project, we redesigned the targeted sonic characteristics to provide more relevant and accurate sounds suitable for audiophiles. The treble characteristics have been redesigned to better match the human ear's tonal perception. This creates a crisp sound signature that is detailed and pleasant to listen to. With a precise pinner at 3kHz that gradually decays into the upper treble, the Black Hole provides a natural and professional treble character. Additionally, the bass response has also been restructured. The bass is very powerful and resonant, with a large 15dB sub-bass shelf. However, the 600-1000Hz midrange remains neutral, providing a realistic, natural timbre for instruments and vocals.
The Black Hole features the second generation of M-Type pressure-relieving acoustic cavities. Formatted in a semi-open back design, the new relaxation cavity is a passive ventilation system that relieves internal pressure and provides a comfortable listening experience without compromising the acoustic seal within the cup. This also reduces sound reflections within the cup, resulting in a cleaner, purer sound.
The overall weight of the headphones has been significantly reduced from previous generations, and the headband has also been upgraded to reduce fatigue. The headband is designed to better fit the user's head shape and distribute weight more evenly, reducing the discomfort of a clamp. In addition to this, a new material is used in the headband to provide richer contact with the head with improved breathability. This clever ventilation design provides a breathable and airy feeling when you wear the earbuds, reducing pressure on your head.
To ensure the high quality and durability of the product, the back cover of the second generation M type pressure relief acoustic cavity is made of aerospace grade aluminum alloy. The decorative part of the headband is also made of aerospace aluminum alloy and has undergone special processing to improve durability and beauty. These selections of materials and manufacturing processes guarantee product quality. Black Hole is the ideal headphone for enjoying music wherever you are. Whether you are a music lover, gamer, or professional musician, we are confident that this product will meet your needs.
