Feature:

10mm PET diaphragm dynamic unit+Imported Knowles 32873 BA driver - 2 adopts the tuning scheme of hybrid drivers with 2-way, 2 acoustic tubes. Bass and mid-range are handled by the dynamic unit. Custom-made Knowles full-frequency balanced armature driver is integrated with it to achieve the sound: Better integration of warm and cold timbre, energy distribution and its full-range imaging. Through repeated adjustments, finally achieve the thick and distinct vocal experience of the original Vesper.

Eye-catching colors -Bright yellow and blue are selected for Vesper2, to emphasize the thick and distinctive personality of the original Vesper. Yellow is pure and flawless. The designer boldly adopts single color. Shells are made by 3D printing. After polishing, apply special resin on the surface and protect the shell, presenting a natural and mellow beauty like beeswax. Blue is gorgeous. Sapphire blue shell and hand-painted faceplate by the artist are vivid and fascinating under the light.

3D printing + Optical hand-painted Shell -The shell is sampled by a large number of human ears. After ergonomic design and acoustic design modeling, the shell is precisely formed through accurate 3D printing technology. The cavity is precise and the internal structure on both shells are as consistent as possible. Ensure better balance of pressure relief in IEM for ideal fit and sound.

Internal structure optimization -In order to achieve the purpose of having a good sound without a very good front-end equipment, QoA tuning team has further optimized the internal structure, with an impedance of 23Ω and a sensitivity of 114db, which means that it is easier for Vesper 2 to play good sound on different devices

8 Core 5N Copper with Silver-plated HIFI Cable -The interchangeable cable design not only adopts the common 0.78mm 2pin on the market, but also facilitates users to replace different wires and experience different sound. Vesper comes with a clean sound. A 8-core 5N silver-plated copper cable with efficient sound signal transmission is used as the wire base to combine with the sound of in-ear monitors, making the low-pitched sound of the earphones more pure, allowing you to enjoy music quietly.

2 kind of eartips, users can choose freely in terms of sound and wearing -Balanced Eartips: The sound is balanced and cohesive, suitable for users with long ear canals. Vocal Eartips: The sound is relaxed and open, and the human voice is sweet and close to the ear, suitable for users with short ear canals.
