【New Arrival】ddHiFi TC19CC Gold (Comet Gold) Pure Silver Digital Signal Cable

Five Sets of Parallel Conductors

Building on the soft flexibility of flat cables, Comet Gold introduces a five‑conductor parallel structure. Power lines run along both sides, separated by CC signal conductors in the center. The data lines use pure silver conductors, with two independently insulated pairs twisted together and wrapped in gold‑plated shielding. This five‑parallel design enables faster device recognition and is ideally suited for one‑meter data transmission.

Who doesn't like gold and pure silver?
The #ddHiFi TC19Gold sample has just been confirmed and the price is already going up.
2026 will be a year of significant increases in material costs.

ddHiFi Memory Semi-In-Ear Planar Earphones: A Chinese Audiophile's Perspective​

"Even among my non-audiophile friends, everyone who tried this ​Memory​ earphones instantly fell in love. The only catch? Even with a powerhouse like the ​vivo X200 Ultra, you’ll still need a power bank when heading out. But honestly, these earphones are the ​all-in-one package—just grab 'em and go. They deliver ​great sound, a sleek look, and all-day comfort, making them the perfect ​​"three-excellence"​​ earphones for on-the-go use."

【New Arrival】ddHiFi TC44Grip Innovate DAC & AMP with PD

Stick, Attach, Plug – Secure to Your Phone in 3 Steps.

For optimal performance, we recommend attaching the attraction pad to your phone case. Position it approximately 10mm from the bottom edge (placement doesn't need to be exact).

Align the bottom groove of the TC44Grip with the attraction pad and attach it securely to the back of your phone. Then, pull out the USB-C plug of the cable and insert it into your phone's charging port.

ddHiFi Surface (E14D) Awarded "Best Buy 2025 Summer" by Japan's Prestigious HiVi Magazine

We are thrilled to announce that the ddHiFi Surface (E14D) earphones have been honored with the "Best Buy 2025 Summer" award by Japan's authoritative audio magazine HiVi (published by StereoSound), securing 3rd place in the Earphones Category 3 (priced above ¥50,000 JPY)!

🏆 About HiVi's Best Buy Award

As one of Japan's most influential AV publications, HiVi magazine conducts rigorous evaluations by expert panels to select the most recommended audio products. The "Best Buy" distinction recognizes not only exceptional sound quality but also outstanding overall product excellence.

🌟 Why Did the Surface (E14D) Stand Out?

● Excellent sound quality performance: It adopts a 5-driver configuration of 1 dynamic driver + 4 balanced armature drivers. Two balanced armature drivers are responsible for high frequencies, two for mid-frequencies, and one dynamic driver for low frequencies. Paired with a specially developed crossover circuit, the sound is balanced and smooth.

● Unique appearance design: The cavity is made by high-precision resin 3D printing and is matched with a metal cover, showing an outstanding texture. The 3D-printed front cavity has high transparency, allowing you to clearly see the 1 dynamic driver and 4 balanced armature drivers inside, as well as the fine connecting wires on the back of the panel. The internal treatment is very clean and visually appealing.

● High-quality cable configuration: The standard-equipped BC120S cable has a cable base made of shielded high-purity OFC with silver plating, and it is a 4-strand twisted cable. It can effectively ensure the transmission quality of audio signals, reducing signal loss and interference.

Special thanks to our distribution partner in Japan @mimisolaportal (mimisola audio) for their dedicated support in bringing ddHiFi's exceptional products to more users in Japan!

"The Surface uses a metallic faceplate with a muted gray finish and a grid-like pattern etched across it. Its appearance resembles a drafting surface or brushed steel, giving it a clean and precise look without calling too much attention to itself."

【New Arrival】ddHiFi HS650 Dedicated USB Hub

Independent PD Fast Charging Port

Supports PD 100W Power Delivery: This high-power port allows for efficient charging.

When the USB-C input port is connected to devices like laptops or tablets that require charging, you can simultaneously connect the PD power port to a PD-compliant charger. This enables both data transfer and battery charging through the docking station.

If you connect power-hungry devices, such as large external hard drives, it’s essential to connect the PD power port to a charger to supplement the required power.
