Reecho acoustic rainbow crossover technology, RAD balanced armature & Reecho acoustic LCP diaphragm dynamic driver

Reecho acoustic rainbow 3.0 unbounded crossover technology, using Japanese Panasonic high-precision matching capacitor, and the frequency division circuit is built in Reecho acoustic exclusive LCP dynamic driver, and the use of 30awg 5N OFC with shielding machine internal line, and Knowles RAD driver to form an efficient hybrid "power", silky sound, and has low distortion, high disturbance resistance characteristics. At the same time, the matching design of a proprietary pocket airflow regulation technology, adjust the airflow in the rear cavity, so that the sound performance is natural and loose.

The industry’s unicorn

In cooperation with HeyGears, a unicorn in the 3D medical industry, Reecho used a high-precision 3D medical printer to make the shell, and adopted a new process to add more details to the shell, so that the appearance is rich and three-dimensional. Thanks to HeyGears’s high-precision printing technology, Spring 2.0 achieves a more accurate acoustic structure.

Ergonomic design

Combined with professional hearing aid solution suppliers, Reecho designed and adjusted the contour of the earphone cavity. Based on the human ear model accumulated in the database of the solution company for a long time, combined with the design requirements of target acoustics, Spring 2.0's contour of the cavity is ergonomic design, fits the ear canal, has higher sound transmission efficiency, and is light and comfortable to wear.

Flagship cable

The standard MW-04 upgraded earphone cable is braided by 392 cores 5N high-purity oxygen-free copper silver-plated wires in 4 strands. With enhanced signal conduction shielding and low micro resistance, the signal-to-noise ratio of the earphone is improved and optimized in the frequency range, which is easy to push and rich in sound details.

A11 Eartips set

In addition to the standard A07 color set and A09 black set, Reecho have updated a new set of eartips A11. A11 uses steps and retractable rotation design, internal acoustic structure is rigorous, provides a high degree of fit, can better fit the ear canal, bring better sound experience.

Quality control

Spring 2.0 implements 1dB quality pairing control, and ensures that 5000 earphones are within the frame line range of 3dB, to ensure that the acoustic data of each pair of earphones is the same.
