The Hidizs MS2 Pro are wired in-ear headphones designed around a hybrid architecture with two transducers, one dynamic and one balanced armature, and a system of interchangeable acoustic filters, allowing the sound signature to be adjusted according to musical styles. This versatility is complemented by a ZA-12 zinc alloy body, ensuring both rigidity and a high-quality finish.
The MS2 Pro combines two complementary transducers to cover the entire audible spectrum: a 10.2 mm dual-cavity dynamic transducer equipped with a PU+PEEK composite diaphragm with a nanometric DLC (diamond-like carbon) coating, and a Silvercore balanced armature transducer developed in-house by Hidizs for high-frequency reproduction. This hybrid architecture is based on a dual magnetic circuit that improves control of the dynamic driver, particularly in the bass registers. The whole unit is housed in a ZA-12 zinc alloy moulded body, whose rigidity limits parasitic resonances while ensuring a neat finish.

Beyond this technical foundation, Hidizs offers three interchangeable acoustic filters that modify the acoustic response according to listening preferences. The transparent ring filter favours an airy and detailed soundstage, particularly suited to classical and acoustic music. This approach is transformed with the red ring filter, which warms the signature to better serve folk and pop. For those looking for more impact in the bass, the black ring filter accentuates the low registers, offering a more energetic presentation for rock and metal.


The MS2 PROs are equipped with a detachable 0.78mm 2-pin cable, making them compatible with most audiophile cables available on the market. The original cable is a silver-plated OFC twisted copper model, measuring approximately 1.2m. This model ends with an asymmetrical 4.4mm stereo jack connector.
