Every now and then, a product lands on my desk that just makes no sense, in the best way possible. I’m talking about the new Hidizs MK10 ArcSonics. After spending some serious time with these, listening to my usual test tracks, my brain immediately priced them somewhere around the $130, maybe $150 mark. The build quality, the tech packed inside, and the sound just felt like they belonged in a much higher price bracket.
Turns out, I was completely wrong. Hidizs has priced the MK10 at a retail price of just $69. That’s a price that makes you do a double-take. It’s not every day you find something that feels this profoundly underpriced, especially once you dig into what makes these things tick.
Build and Design
From the moment you pick them up, the Hidizs MK10 feels different. These aren’t your typical plastic earbuds. The shells are crafted from a solid chunk of ZA12 Zinc Alloy, and they feel premium. Hidizs calls the process “liquid-forging,” and the result is a dense, mirror-polished chassis that feels substantial and durable. This isn’t just for looks, either. A heavy metal shell like this is far better than plastic at crushing internal resonance—those tiny, unwanted vibrations that can muddy up the sound. The result is a cleaner, more precise audio experience right from the get-go.
The faceplate has this cool, almost futuristic look that reminds me of something out of Star Wars or Predator. The one downside to this beautiful finish is that it’s a total fingerprint magnet, so you’ll be wiping them down a lot if you want to keep them looking pristine. Comfort is surprisingly good, though. Despite the metal build and reassuring weight, the ergonomics are solid. The nozzle is a bit on the shorter side, so they don’t feel too intrusive, and I was able to wear them for a couple of hours straight with no real fatigue.
The Tech Under the Hood
This is where things get wild for a sub-$70 IEM. Inside each earpiece of the Hidizs MK10 is a 10mm dual-magnetic circuit dynamic driver. The real star of the show, though, is the diaphragm—it’s made from Silicon Carbide Crystal. That’s not your typical material; it’s a rare and advanced composite known for being incredibly rigid while also being extremely lightweight. In simple terms, this means the driver can move faster and more accurately, which translates to cleaner sound, less distortion, and way better detail resolution. It’s the kind of high-performance tech you usually see in much more expensive gear.
The driver is housed in a dual-cavity structure, which acts like a tiny “sound shock absorber.” It helps control airflow around the driver, allowing the bass to dig deeper and the treble to extend further without getting messy. It’s this clever internal engineering that helps the MK10 deliver such a controlled and dynamic sound across the entire frequency range.
The Sound
One of the most impressive features of the Hidizs MK10 is its versatility. You get a set of three interchangeable pneumatic tuning nozzles, but it doesn’t stop there. By combining these three nozzles with the two different types of included liquid silicone eartips, you can effectively create up to six distinct sound styles. This isn’t a gimmick; swapping the filters genuinely and noticeably changes the sound signature.
Switching to the black nozzle gives you this visceral, powerful bass that’s perfect for EDM and rock, adding a satisfying weight and impact to the low end. The silver nozzle, on the other hand, opens up the top end completely, adding a layer of air and sparkle that makes classical and acoustic pieces just sing with crystalline clarity. My personal favorite, however, is the red nozzle. It strikes a beautiful balance, delivering an intimate and natural sound where vocals and jazz really shine without any frequency feeling over-emphasized.
The Listening Experience
So, how does it all come together? The sound signature is based on the popular H-2019 target curve but with Hidizs’ own musical flavor mixed in. I found they sounded great out of the box, but they definitely settled in nicely after a day or two of use.
The bass on the Hidizs MK10 is all about punch and texture rather than just pure sub-bass rumble. It’s fast, tight, and incredibly dynamic. Kick drums have a satisfying kick, and bass guitars sound engaging without ever bleeding into the other frequencies. This controlled low end is a testament to that well-designed driver.
The midrange is where these IEMs absolutely shine. Vocals, both male and female, come through with a natural, uncolored tone that is just fantastic for this price point. I was blown away by how good electric guitars sound on rock and metal tracks. There’s a certain crispness and clarity that makes distorted riffs and solos really pop. This might just be my new default recommendation for metalheads on a budget.
Using the red balanced nozzle, the treble is well-extended and detailed without being harsh or offensive. The silicon carbide diaphragm does a fantastic job of revealing those tiny micro-details in a mix—the subtle shimmer of a cymbal or the sound of fingers on a fretboard. The soundstage is also shockingly wide for a $70 IEM. There’s a great sense of separation between instruments, and the imaging is precise enough that you can easily place sounds in the mix, making these a surprisingly great option for gaming, too.
Final Verdict
I just keep coming back to that price tag. For $69, the Hidizs MK10 offers a fantastic metal build, advanced driver technology, genuine tuning versatility, and a sound profile that competes with IEMs costing twice as much. The value here is genuinely kind of insane.
This could easily be the new budget king for its price bracket, especially for anyone who loves a dynamic, punchy, and detailed sound. It has seriously shaken up what I thought was possible for under $100. What’s your current budget champion?
