In this article, I review the Tanchjim Origin IEMs. The Origin oozes with Tanchjim’s classic design language and a 5th-generation 10mm DMT dynamic driver. It’s priced at 259 USD.

Tanchjim is a Chinese audio company known for its precise engineering, elegant design, and a focus on high-fidelity sound. Over the years, the brand has built a strong reputation among audiophiles and casual listeners alike for delivering impressive performance at competitive prices. Their tuning typically leans towards clarity and technical accuracy, often appealing to fans of a more analytical presentation.

Some of Tanchjim’s most popular IEMs include the Tanchjim Oxygen, praised for its natural tonality and balanced sound; the Tanchjim Hana, known for its sleek aesthetics and refined treble; and the Tanchjim Zero, a budget-friendly model that gained acclaim for its detail and neutral tuning in its price bracket.

Design

Those familiar with Tanchjim will immediately recognise the Origin’s design language. The stainless steel shells come in either a polished mirror or textured frosted finish, depending on the version. The right faceplate features the Tanchjim logo, while the left side is marked with the Origin model name.

Build quality is excellent, and the earpieces have a reassuring heft that enhances their premium feel. Origin utilises a guided air pressure design, with a vent located in front of the 2-pin sockets. This prevents air-pressure build-up and allows the dynamic driver to breathe more freely.

The stock cable is a Litz-braided silver-plated copper design. The plug, Y-splitter, chin slider, and 2-pin connector housings are all made from the same stainless steel as the shells, reinforcing the cohesive design and adding durability. While the cable may look somewhat generic, its handling and drape reflect its high quality.

Sound

Gear used for testing includes the Tanchjim Stargate II, HiBy R6 III 2025, and SMSL RAW-MDA1. The Tanchjim Origin is relatively easy to drive and doesn’t require a particularly powerful source. That said, it benefits from a quality DAC or amplifier (Tanchjim’s own Stargate II proved to be an excellent match).

As many others have stated, the tuning nozzles do almost nothing to the sound profile, so for that reason, I’m not going to talk about them here. For clarity, however, my impressions below are based on the Standard (default) filters.

The Tanchjim Origin has a tastefully tuned sound signature that flirts with neutral but adds some extra warmth and contrast. It’s a natural-sounding IEM with a focus on vocals and midrange but at the same time, gives plenty of love in the bass and treble departments too.

Bass

Origin’s bass is one of those interesting ones. It’s tastefully restrained in quantity, yet it hits with authoritative punch and carries ample body. Attacks and decays feel effortlessly natural—warm, yet agile. True bassheads might be left wanting, but for me, the bass is tuned just right. There’s a slight sub-bass roll-off that gives the ultra-lows a gentler rumble, but that also allows the mid-bass to step forward—a trade-off I can definitely appreciate, and one that’s been conspicuously absent from many ChiFi IEMs of late.

Midrange

Vocals and instruments with lower fundamentals—like male vocals, guitars, and cellos—sound natural and well-separated, without added weight or congestion. Just like the bass, Origin’s midrange oozes naturalness. The steady rise from 1–3kHz lends clarity and articulation, giving vocals and instruments a lifelike presence without tipping into shoutiness. It’s a clean, well-balanced tuning that avoids muddiness and excels with vocal-centric and acoustic music.

Treble

It’s one of the few IEMs I’ve reviewed recently that I’d genuinely describe as having sparkle in the treble. There’s a moderate dip around 4–5 kHz, which helps reduce sharpness and sibilance, especially on vocals and cymbals. A subtle lift near 7–8 kHz brings detail and air to the mix, while letting the midrange retain its role as the star of the show. The treble is well-detailed but never overbearing—a refined balance that complements the overall tuning.

Soundstage & Technicalities

Origin’s soundstage is moderately sized—neither expansive nor cramped, but comfortably in between. The airy treble helps to widen the stage and create some spread between elements, while the forward midrange and meaty bass contribute to a strong sense of depth. What stands out to me is the instrument separation and the resolution on offer from the single dynamic driver. Imaging is precise too, making it easy to place instruments and vocals within the mix.

Comparisons

EarAcoustic Audio SPA Hi End MAX

The EarAcoustic Audio SPA Hi End has a more energetic V-shaped tuning. It has an elevated bass that carries more rumble and punch but also has a thicker midrange as a result. The sound is coloured while the Tanchjim Origin steers closer to a neutral tuning with a flatter bass shelf and more restrained upper mids and treble. The Hi End MAX leans into a more dynamic and contrast-heavy sound profile that prioritises excitement over tonal accuracy.

Simgot EA1000

It might not look like much of a difference but the EA1000 is noticeably leaner and less dense. EA1000’s bass has less meat on the bone and isn’t as textured. This carries over into the midrange, where the EA1000 is more spacious but not as natural. Both IEMs have similar levels of treble and detail but the Simgot has a slightly wider soundstage.

Verdict

The Tanchjim Origin is a strong addition to the brand’s already impressive lineup. It retains the core Tanchjim traits—airy treble, tight bass, and a detailed midrange—while introducing a warmer, more organic tonality. While there are some capable single dynamic driver alternatives at lower price points, the Origin holds its own with a refined and engaging sound that’s hard to fault.
