RAPTGO Release


Litz Taiwan Single Crystal Copper & Long Crystal Copper Silver-Plated Conductor

The release is a shielded version of upgraded earphone cable jointly created by RAPTGO and DDHIFI, which adopts Taiwan Bandung single crystal copper and long crystal copper silver-plated conductor. It features the same shielding structure as DDHIFI's Nyx and a brand-new mid-part cable device design. RAPTGO Release follows with excellent performance, stable and smooth signal transmission, and soft feeling of its body to effectively avoid Stethphone Effect.


4.4mm Shielded Wire

To simplify the process, most of the headset shield cable on the market is not connected to the 4.4mm plug ground cable. To enhance the anti-interference of the earphone cable in the development process, the shielding layer was connected to the ground wire of the 4.4mm plug to increase the cleanness of the sound.


RAPTGO Release


Well-Knit Wire Structure

The release features a well-knit structure in cable and shielding. This cable adopts four 0.05 mm * 7 * 7 wires as the core, and four 0.05 mm * 8 * 8 wires as the shielding.


High Grade Insulation Material

RAPTGO Release characterizes Inner and exterior insulation with high-grade insulation material, including high precision foam HDPE from Japan NUC, which is made in Japan, and high transparency SoftFlex PVC, which is made in the USA.

Designed to Associate with RAPTGO's Products

When Release works with RAPTGO's products, the low frequency was significantly improved, especially in terms of fullness and diving of any frequency and in terms of the resolution of the background instruments. The overall listening sensation of the transient improvement is relatively obvious, especially when dealing with fast songs, more leisurely than before.
