The well-known Dongguan-based portable audio brand Hidizs continues to add to its Mermaid Series IEMS line-up and is releasing a new hybrid model called the MS2. The model number reflects the number of drivers it has: 1 DD + BA. The dynamic driver is a 10.2mm unit, consisting of two coils and two chambers. Its diaphragm is the result of a new Hidizs development using a macromolecular compound, version 2.0. The BA driver is none other than the RAD-33518-P183 from Knowles. In this sense, Hidizs is leaving nothing to chance and is committed to adding quality to its drivers at a very reasonable price: $89. To finish with the capsules, these have been constructed with a German eco-friendly resin body, while the mouthpieces have been gold-plated. The connection chosen for the capsules is a 2pin 0.78mm. The cable used is a mix of four core strands: two are high purity silver wires and the other two are OFC cables. To complete the product, Hidizs has provided a very distinguished packaging, featuring a beautiful storage box, in a very compact and appropriate package.


Hidizs offered me this model, in exchange for writing an honest review. I want to make it clear that all my opinions written in this review have not been conditioned by this fact, nor will I ever write anything that I do not really think or feel here. I will only write about my personal opinion in relation to the revised product.
