Riccardo Robecchi of Soundphile Review finds the HIDIZS MK12 Turris surprisingly accomplished for its price. Awarding it 8.8/10, he highlights a combination of enjoyable tuning and impressive technical performance, with the 91% magnesium diaphragm playing a meaningful role in its presentation.
Aluminum Comfort With One Major Limitation
The MK12 uses entirely aluminum shells with an organic-looking faceplate design. Despite the metal construction, Robecchi finds the earpieces lightweight and exceptionally comfortable, saying he can wear them for hours and barely feel them. Their shape also accommodates both deeper and shallower insertion.
The lightweight cable is similarly unobtrusive. However, passive isolation is the clear drawback of the design. Robecchi reports almost no meaningful noise reduction, making the MK12 unsuitable for noisy environments unless the listening volume is raised excessively. He therefore considers it best suited to quieter surroundings.
Red Filters Find the Right Balance
Three removable filters provide different tuning options. Robecchi finds the gold and silver filters too emphasized through the upper mids and treble, while the red filters achieve a much better balance. His detailed sound evaluation consequently uses the red configuration.
With those filters, the MK12 approaches neutrality while retaining energy and physicality. Bass extends significantly into sub-bass territory and combines impressive texture with speed, detail and physical impact. Mid-bass adds a little warmth without becoming intrusive.
The midrange remains balanced, with gentle emphasis toward both ends and slightly greater energy in its upper region. Robecchi finds this helps high-pitched instruments and female vocals sound lively without disrupting the overall balance.
Technical Ability Beyond Expectations
Soundstage is both wide and deep, creating the impression of a large listening space. Imaging is convincing, while instrument separation is excellent even at lower volumes and during complex recordings.
Treble is detailed and generally tame rather than overpowering. Robecchi considers its overall weight close to ideal, although multiple middle- and upper-treble spikes can add audible zing and occasionally become aggressive for treble-sensitive listeners.
The MK12 is also very easy to drive. During testing with multiple source devices, Robecchi found that additional amplification was unnecessary.
HIDIZS supplied an advance review unit, with the review disclosing no further commercial arrangement.
Overall Assessment
Robecchi’s judgment of the HIDIZS MK12 Turris is strongly positive. He believes the magnesium diaphragm produces a noticeable, if not dramatic, difference and is particularly impressed by the IEM’s physical transients, detail and technical capability.
Its poor passive isolation and occasional treble spikes are meaningful limitations, but neither outweighs its strengths. For listeners wanting an almost-neutral, versatile presentation with impactful bass, detailed mids, relaxed overall treble and strong spatial performance, Soundphile Review considers the MK12 exceptionally enjoyable, comfortable, well built, and impressively capable across a wide variety of music genres.
