The Hidizs Mermaid MM2 is a hybrid in-ear monitor (IEM) that features a unique driver configuration comprising a 6mm low-voltage magneto-static balanced membrane driver and a 10.2mm dynamic driver. The magneto-static driver utilizes a micron-level diaphragm, providing enhanced transient response for high frequencies, ensuring clarity and detail. The dynamic driver is designed for improved mid-bass range performance, delivering a deeper and punchier bass response while maintaining smooth and detailed mids. The MM2 incorporates three detachable tuning valves, allowing users to switch between balanced, treble, and bass sound signatures, providing versatility depending on personal preferences. Its construction includes an eco-friendly resin body and a lozenge-cut faceplate that combines aesthetic appeal with comfort. The IEMs come with a high-purity quad-core cable, which combines oxygen-free copper (OFC) and silver wires for a refined listening experience. Additionally, the standard 0.78mm 2-pin design allows for cable upgrades, and the product is packaged with a stylish eco-friendly leather carrying case. It also boasts Hi-Res Audio certification, ensuring that it meets high-quality sound standards.
