A Casual's Review of the Hidizs MK10 ArcSonics IEMs: Clean, Detailed, Versatile.

Disclaimer: I’m not an audiophile, and this review focuses on personal listening impressions rather than technical analysis.

This unit is part of a review tour by the Mindanao Audio Club and was provided by Hidizs. All opinions are my own. Audio is subjective, so your experience may vary.

Pros

✔️ Clean, detailed sound with good clarity and separation
✔️ Strong technical performance for the price

✔️ Easy to drive, works well with basic sources
✔️ Good imaging and positional cues for gaming

Cons

❌ Bright tuning may not suit treble-sensitive listeners
❌ Not ideal for those who prefer warm or bass-heavy sound

❌ Basic pouch offers limited protection

What’s in the box

  • The MK10 IEMs
  • Stock cable
  • 3 pairs of tuning nozzles (Low / Balanced / High frequency)
  • 6 pairs of silicone eartips (S, M, L; wide and narrow bore)
  • Carry pouch
  • Manual and warranty card

IEM Shell Design

The MK10 uses metal shells with a noticeable weight of around ~13.3g per side with the nozzles attached. The shells are relatively large.

The faceplate features a smooth, rounded design with a curved cavity running across it. A visible seam runs along the edge where the faceplate meets the main shell. There are two pressure relief vents, one near the nozzle and another at the rear.

The silver version has a full mirror finish across the entire shell. A black version is also available.

Stock Cable

The included cable is a braided design with a translucent outer sheath. It uses a standard 2-pin 0.78mm connector with color indicators (red for right, blue for left), and comes in a 3.5mm termination with a 4.4mm option available. The connector housing, Y-splitter, chin slider, and plug housing are all made of plastic. There are pre-formed earhooks near the connectors.

Carry Pouch

The included case is a black pleather pouch with the Hidizs logo embossed on one side. It uses a spring-style clasp where you press the sides to open, and it snaps shut on its own. It’s compact and easy to carry around, but don’t expect it to give your gear much protection. It’s more for keeping things organized.

Stock Eartips

The MK10 includes 6 pairs of silicone eartips in sizes S, M, and L, with both wide bore and narrow bore options. The eartips are packaged on a plastic holder. Comfort-wise they’re all fine.


Tuning Nozzles

The MK10 includes three interchangeable tuning nozzles: Deep Black (Bass), Crimson Steel (Mids/Vocals), and Shimmering Silver (Treble). Each nozzle is made of metal and features a mesh filter at the tip.

The nozzles are screw-on and have color-coded rings for identification, though the indicators are on the side that attaches to the IEM.

General Usage Impressions

The MK10 is easy to drive and works well even with basic sources like a phone or a simple dongle.

Because of the size and weight of the shells, fit may vary depending on your ears. The weight is noticeable at first, but it settles during longer sessions and remains fatigue-free.

The mirror finish looks great but is very prone to fingerprints during regular use.

The tuning nozzle system adds flexibility, but in practice it can be a bit inconvenient since you need to remove the eartips to check which nozzle is installed.

Sound Impressions

For consistency, I stuck with small narrow bore tips. The MK10 came with the red nozzle preinstalled, so that’s what I started with.

Nozzle swaps are noticeable, but they don’t drastically change the overall tuning. Most of the differences are in the upper mids and treble.

For gaming, I used Overwatch to check things like imaging, separation, and clarity during busy fights.

Black Nozzle (Bass)

Tuning: Sounds a bit fuller compared to the others, but still on the clean side. Just adds a bit more weight.

Bass: Sub-bass has good rumble and presence. Mid-bass hits a bit harder here, but still stays tight and controlled.

Mids: Mids sound a bit less lean. Vocals have slightly more body, but it’s still not what I’d call warm.

Treble: Smoothed out a bit compared to the other nozzles. Still has some energy, just less sharp compared to the other two.

Technicalities: Stage feels a bit more closed in. Imaging is still accurate, just less sharp. Separation is decent, but in busier tracks it can start to blur together.

Gaming: Easier to listen to for long sessions. Things can blur a bit during hectic fights, but positioning is still easy enough to follow.

---

Red Nozzle (Mids / Vocals)

Tuning: This is the most “neutral” out of the three. Clean with a slight upper-mid focus.

Bass: Bass stays controlled and doesn’t stand out. Sub-bass is there when needed, but not really emphasized.

Mids: More forward compared to black. Vocals and effects are easier to pick out, especially in busy tracks.

Treble: Has some energy, but not overly aggressive. Sits right between the black and silver nozzles.

Technicalities: Stage opens up a bit. Imaging is more precise, and separation is easier to follow, especially for vocals and effects.

Gaming: Good balance overall. Voices and ability sounds are easier to pick out without being too sharp.

---

Silver Nozzle (Treble)

Tuning: Brightest of the three. Leans more into clarity and detail.

Bass: Bass takes a slight step back. Clean, just less noticeable overall.

Mids: Upper mids are more forward. Vocals pop more here, but can get a bit sharp.

Treble: Most energetic here. More sparkle and bite, and this is where it can get spicy depending on the track.

Technicalities: This feels the most open. Imaging is the sharpest, and separation is the easiest to pick apart, especially in busy tracks.

Gaming: Best for clarity. Footsteps and directional cues are the easiest to track, but it can get fatiguing over longer sessions.

Comparisons

Comparing the MK10 with other units I have that use interchangeable tuning nozzles. For consistency, I used the red nozzle on the MK10, the gold nozzle on the MK12, the green nozzle on the T6, and the silver nozzle on the Klean SV for this comparison.

Hidizs MK10 vs Hidizs MK12 ($159 USD)

The MK12 sounds smoother and a bit warmer overall, while the MK10 leans cleaner and slightly brighter. The MK10 feels more energetic and sharper, especially in the treble, while the MK12 is more relaxed and easier to listen to. The MK10 comes off more defined, while the MK12 sounds fuller and more laid-back.

Hidizs MK10 vs Tinhifi T6 ($119 USD)

Both lean clean and slightly bright, but the T6 sounds thinner and more analytical. The MK10 has more weight and comes off more balanced overall, while the T6 pushes clarity harder but can feel a bit dry. The MK10 is easier to listen to, while the T6 feels more focused on detail.

 

Hidizs MK10 vs Kefine Klean SV ($54 USD)

The Klean SV sounds more neutral and controlled, while the MK10 is more energetic overall. The MK10 has more sub-bass and a bit more sparkle, which makes it sound more lively, while the Klean SV feels more even and relaxed. The MK10 is more engaging, while the Klean SV is easier to listen to for longer sessions.

Final Thoughts

The MK10 is really solid overall. It leans clean and slightly bright, with good technical performance and just enough flexibility from the tuning nozzles to adjust it to your preference.

Build quality is one of its strongest points. The full metal shells and mirror finish make it feel more premium than its price suggests, even with the usual tradeoffs like fingerprints and a basic pouch.

Sound-wise, it’s not for everyone. If you prefer something warm or bass-heavy, this probably won’t be your first pick. But if you like a clean, detailed sound with good clarity and separation, the MK10 delivers.

Personally, I enjoyed the black nozzle the most since it gave me the best balance for both music and gaming.

For the price, it’s a strong all-rounder that focuses more on clarity and technical performance rather than fun or coloration.
