CVJ X R2E3 Mermaid 2 are new in-ear headphones developed in collaboration between CVJ and R2E3 Acoustics. This is an updated version of the Mermaid model, which has received improvements both in the external design and in the driver design. Having retained the recognizable shape of the case, the developers made minor changes to the seating part to improve comfort during long listening. The panels received an additional decorative layer with a double hollow structure, emphasized by a dark relief pattern and a gold insert made by vacuum deposition.
The model is equipped with an external pressure relief system, which optimizes air circulation in the case and reduces the load on the membrane. This solution allowed us to achieve more precise speaker operation, reduce distortion and improve the perception of low frequencies. The case is made of aluminum with anodized and engraved surface using 5-axis milling. Contact elements are made of beryllium copper, providing a reliable connection and stable operation.
Inside, there is a single dynamic emitter with a beryllium diaphragm, which is characterized by high rigidity and lightness. It is complemented by a powerful N53 magnet with an induction of 1.5 Tesla and a non-standard driver architecture, which uses independent sound chambers and precision ventilation holes with a tolerance of 0.05 mm. All this ensures a low level of distortion and precise impedance matching.
Fine tuning of the acoustics allowed to achieve a balanced transmission of all frequency ranges. In the range of 1-2 kHz, the emphasis is on a more saturated and rounded sound of the middle, and in the area of 4-5 kHz, the sharpness is reduced to reduce sibilants. Low frequencies sound voluminous and relief, the upper range retains transparency and clarity, which is especially evident both in modern pop music and in classical music.
Mermaid 2 is equipped with a cable made of combined conductors: silver-plated copper and monocrystalline copper. In total, the cable uses 1016 cores, which ensures a tight and reliable connection. The set also includes replaceable 3.5 and 4.4 mm plugs.
The listening impressions emphasize the richness of the vocals and comfortable delivery – both male and female voices are transmitted softly and expressively. High frequencies are delivered delicately, without being tiring, and the overall sound space is perceived as solid and detailed, with clear separation of instruments. Thanks to the deep development of the design and tuning, the Mermaid 2 manages to combine a natural presentation with an expressive stage and emotional involvement.
