HIDIZS MK12 X DUCBLOKE Review - DucBloke

The HIDIZS MK12 X DUCBLOKE carries unusual significance for DucBloke because he was not simply reviewing the finished IEM. He worked on its tuning and created the PEQ settings designed specifically for the collaboration. In this follow-up, he explains how his preferred Neutral profile reshapes the MK12 X DUCBLOKE and helps owners load that tuning onto a compatible device.

The Tuner Behind the Collaboration

DucBloke explains that people had begun receiving the MK12 X DUCBLOKE and that he was hearing positive feedback from listeners. He had also been using the IEM with his PEQ loaded, while continuing to send the settings to subscribers who needed them.

His explanation gives insight into the decisions behind the collaboration. Rather than favoring the strongly V-shaped response shown by the IEM before PEQ, DucBloke says his personal preference is a U-shaped tuning.

For his Neutral setting, he reshaped the transition from mid-bass into the lower mids to clean up the vocal region. He also increased treble substantially, particularly around 6kHz, taking it toward the point of sibilance before backing it off.

PEQ Is Part of the MK12 X DUCBLOKE Experience

The Neutral profile uses eight PEQ bands extending from 21Hz to 15kHz. DucBloke describes extending the upper frequencies beyond 15kHz while adjusting the bass and lower-mid transition to achieve the balance he wanted.

Importantly, he rejects the idea that his approach simply darkens or muddies treble. He explains that he adds treble when an IEM needs it and reduces it when the original presentation is too bright.

The result turns the underlying V-shaped response into the U-shaped presentation he prefers. Owners have access to a Sparkle profile, which DucBloke demonstrates as a brighter alternative in the treble region.

Supporting the IEM After Release

Another notable part of the video is DucBloke’s continued involvement after the collaboration began shipping. The tutorial itself was created after a subscriber asked how to load the PEQ settings.

He walks viewers through importing his profiles and pushing them to a compatible PEQ device, while also offering direct help to listeners struggling to obtain or use the settings. He notes that HIDIZS had distributed the PEQs and was also putting them on its website.

Overall Assessment

This video offers something different from a conventional MK12 review: the perspective of the person whose name and tuning are attached to the HIDIZS MK12 X DUCBLOKE.

DucBloke explains exactly how he shaped the PEQ, from bass and lower-mid adjustments to vocal clarity and extended treble, while providing multiple profiles for different preferences. For MK12 X DUCBLOKE owners, his continued support and detailed explanation make the collaboration feel like more than a name on the product—it reflects his own tuning philosophy and hands-on involvement.
