Xishui XSP2 is a long-awaited flat-head earphone. It has been four years since the previous product OURART QJ21 and Hesse ANSATAPRO. Today, we are very honored to introduce this new earphone to you.
XSP2 uses a customized 15mm DLC diamond-like coated diaphragm large magnet dynamic unit, which can provide excellent sound quality performance. In addition, it is equipped with a unique earphone sound guiding rear cavity structure, including a buffer sub-cavity and a set of interconnected flute tubes. This design can not only optimize the sound propagation path but also enhance the details and layering of the sound quality.
Compared with QJ21 and ANSATA PRO, XSP2 has more vivid sound color, full and thick mid-frequency, and better ultra-high frequency extension. Its sound quality exceeds ANSATAPR0, and the listening experience is better than QJ21. The sound color of XSP2 makes the voice more dynamic, can better express emotional fluctuations, and the human voice is full of strength. In terms of vocal performance, male voice is comparable to QJ21, while female voice is brighter, more delicate and transparent than QJ21. In addition, XSP2 also has better sound field depth. Its sound texture is soft, but it can burst out with impact at critical moments.

In terms of appearance design, the shell adopts an ear return structure, and the back panel is made of blue stable wood. The main color is black, with royal blue and gold embellishments, showing a low-key and luxurious style.

Xishui XSP2 uses CNC metal aluminum as the main cavity, combined with high-precision 3D printed resin sub-cavity, and a composite structure of multiple materials such as stable wood backboard. Compared with the previous models, XSP2 has a more complex structure and more mature tuning.

In addition, the Xishui XSP2 is also equipped with a thick 2-core low-impedance single crystal copper silver-plated audiophile upgraded wire. The wire diameter is 2.2 mm, with 100 wires per core. It is made of high-purity single crystal copper silver-plated material, which is soft and heavy.

Resin printing sub-cavity, which is a sound-guiding rear cavity structure of headphones, includes a buffer sub-cavity and a group of interconnected flute tubes. It can make the sound field of headphones more natural and eliminate false low frequencies. It can also extend the frequency band response width of headphones.

Hand-made scaffolding circuits are one of the keys to making high-quality headphones. Compared with traditional machine manufacturing methods, hand-made scaffolding circuits pay more attention to details and precision. During the production process, craftsmen will carefully select and process materials to ensure that each wire meets the requirements. They will carefully match pure silver round wire and copper together to achieve the best sound quality.
Another advantage of hand-made scaffolding circuits is its flexibility. Craftsmen can customize according to different headphone models and needs to meet the pursuit of sound quality by different users. They can adjust according to personal preferences and music types to ensure that each headphone can provide a good sound quality experience.
Using pure silver round wire and copper as the in-machine wire for hand-made scaffolding circuits can significantly improve the sound quality of the headphones. Pure silver round wire can provide faster high-frequency output and make the sound clearer; copper can enhance the performance of mid-low frequencies and make the human voice fuller. The fine production and flexibility of hand-made scaffolding circuits enable each headphone to provide a sound quality experience according to the needs of the user.
