Video reviews we found, each condensed to its verdict. They do feed the HearWiki score, at a measured weight below what a published written review carries.
6:56The reviewer strongly condemns the Hidizs MD4, calling it the worst IEM they have ever heard, with extremely peaky treble, muddy bass, and poor overall sound quality. They advise against purchasing it and recommend the balanced mode if forced to use it, while praising the build quality and accessories.
12:08The reviewer initially disliked the Hidizs MD4, finding it harsh and bass-light with foam tips, but after switching to silicone tips and the warm tuning setting, he found it acceptable, though not outstanding. He concludes it's a competent but situational IEM that doesn't justify its $189 price, giving it a 5 out of 10 and suggesting alternatives like the Kiwi Ears Orchestra Light for a bit more money.
8:54The reviewer praises the Hidizs MD4 as a well-built and innovative IEM, highlighting its unique physical EQ switch that offers four tunings. They find the sound quality satisfying, especially with the balanced setting, and consider the included accessories and build quality excellent for the price. Overall, they recommend it as a great value.
18:49The reviewer praises the Hidizs MD4 for its unconventional, mid-range-centric tuning that deviates from the typical V-shaped curve, offering a natural and full-bodied sound, especially for vocals and acoustic instruments. They highlight the adjustable switches and ear tips that allow for flexible tuning, and conclude that these are objectively good-sounding in-ears for the price, though they lack extreme bass or treble extension.
15:04The reviewer praises the Hidizs MD4 as a well-built, comfortable, and versatile IEM with four tuning switches. He finds its sound signature balanced, clean, and highly resolving, with a particularly smooth and safe treble. He recommends it for listeners seeking a mature, refined tuning rather than bass-heavy sound, and notes it excels with rock, jazz, and electronic music.
