Hidizs is a Chinese audio company with a wide range of products, many of which are used and enjoyed by head-fi members today. Making everything from DAPs, DACs, amps, and most recently earphones, they have managed to expand their portfolio of products to create a blossoming audiophile ecosystem.

My first experience with one of their products was the Sonata HD amp/dac dongle. Overall I really enjoyed the portability, build quality, sound, and customisable firmware for such a simple product, and I still use it to this day with great effect. 

The MS2 is the first earphone that I have tried from Hidizs, and it enters a challenging market, especially in the IEM space where Chi-Fi has established a powerful position in the value/performance arena over the last several years. As the name alludes to, these are set up with 2 drivers, one being the now-famous Knowles RAD-33518-P183, while the second driver is Hidizs’ very own proprietary 10.2mm dynamic driver made from a macromolecular compound. Both drivers are contained within two chambers. The MS2 capsules are built from german-made, eco-friendly resin.

Will the MS2 hold its own? Let’s crack open the packaging and find out!
