Affordable, Tunable… and Ultimately Forgettable
The budget IEM market is absolutely flooded right now, and every new release claims to be the one that finally punches way above its price. The TWISTURA D-Minor, developed by LEAudio, comes in swinging with a few interesting ideas — a 10mm dynamic driver, interchangeable tuning filters, and a price hovering around the $30 mark.
On paper, that’s a solid recipe. In practice? It’s… fine. Not bad. Not great. Just kind of there.
The D-Minor uses a metal-and-resin shell that looks nicer than you’d expect at this price. It has a bit of visual weight to it, though the housings feel slightly chunky in the ear. Comfort will really depend on tip choice — once dialed in, they’re usable for longer sessions, but they’re not the kind of IEMs you forget you’re wearing.

The cable is serviceable and nothing more. It works, it doesn’t tangle too badly, and that’s about the highest praise it earns. Check it out on Amazon!
This is where my feelings landed squarely in the “meh” category.
The D-Minor doesn’t do anything offensively wrong, but it also doesn’t do much to stand out. The tuning feels safe, restrained, and a little uninspired — which isn’t shocking at this price, but still worth calling out.

Bass is present, reasonably controlled, and polite. There’s enough low-end to keep things from sounding thin, but it lacks punch and texture. If you’re expecting slam or rumble, this isn’t the set for you.
The midrange is probably the strongest part of the D-Minor. Vocals come through clearly, and nothing feels wildly recessed or shouty. That said, there’s no real sense of excitement or richness here — it’s competent, not engaging.
Treble is smooth and somewhat muted. It avoids harshness, which budget IEMs often struggle with, but it also lacks air and sparkle. Details are there if you listen for them, but they don’t jump out.
One of the headline features is the swappable tuning filters, designed to adjust the sound for different genres. They do make a difference, but it’s subtle. You’re not transforming the D-Minor into three distinct IEMs — more like small nudges to the existing sound.
It’s a nice bonus at this price, just don’t expect miracles.
Here’s the thing: at around $30, it’s hard to be too harsh.
The D-Minor isn’t bad — it’s just very middle-of-the-road in a segment full of surprisingly strong options. There are other budget IEMs that sound more exciting, more dynamic, or more refined. The TWISTURA plays it safe, and that safety makes it easy to forget once you move on.
The TWISTURA D-Minor is a perfectly acceptable ultra-budget IEM that doesn’t embarrass itself — but it also doesn’t leave much of an impression.

If you find it cheap, on sale, or bundled with something else, it’s an okay pickup. If you’re hunting for something that really stands out sonically, there are better options even at this price point. Check it out on Amazon!
Not bad. Not great. Just… fine.
