Tanchjim Introduces The All-New & Upgraded Earphone - The One

Introducing the all-new Tanchjim One, a brand-new single dynamic driver IEM designed with a high-quality medical-grade Resin material shell and a specially developed triple-composite patented rear cavity design. Tanchjim One has a simple, compact design that allows for an easy and comfortable wearing experience, suitable for different wearing styles, Straight Down and Around the Ear. Tanchjim One is available in three different variants. One variant includes a 3.5mm cable, one with a 3.5mm mic cable, and one with a Type-C cable and a 3.5mm cable. Type-C cable has built-in DSP which provides high-res 24-bit audio signal decoding.

Featuring A Specially Developed 10mm Dynamic Driver For Clean Sound

Tanchjim One delivers robust audio performance, thanks to its specially developed 10mm dynamic driver unit. This driver features a top-notch titanium dome structure and a diaphragm made from PU+PEEK composite materials, resulting in a crystal-clear sound with minimal distortion and intricate details. These earphones achieve an impressive dynamic range and notably reduce distortion, enhancing imaging and positioning for a more immersive audio experience. Tanchjim One, expertly fine-tuned by Tanchjim's professionals, emerges as a remarkable audio marvel, presenting each piece of music like a captivating story.

Built-In High-Performance DSP Audio Decoding Chip In Type-C Variant

Tanchjim One offers a Type-C termination option equipped with an integrated 24-bit DAC, facilitating high-resolution audio signal decoding that supports output at 44.1kHz, 48kHz, and 96kHz sampling rates. This Type-C variant ensures cleaner output and delivers excellent performance directly with your smartphone or PC/laptop. Tanchjim One also features a high-performance miniature earphone amplifier and a low-noise microphone circuit, with the microphone recording boasting a high-spec input at 24-bit 96kHz. Additionally, the judicious application of DSP technology enhances the exceptional audio quality experience provided by One.

Ultra-Smooth Surface Design, Rear Cavity Structure & Anti-Interference Filter

The internal cavity design of Tanchjim One boasts an exceptionally smooth surface that effectively reduces resonance caused by reflections at ultra-high frequencies, resulting in an enhanced acoustic performance across all three frequency ranges. This design allows the earphones to deliver a clear and precise high-frequency output. Tanchjim One also incorporates a patented Triple Composite rear cavity structure, which plays a crucial role in fine-tuning the lower frequencies, resulting in deeper and more robust bass response. The bass becomes more controlled, tight, and presented with a refined quality. Additionally, Tanchjim One includes an anti-interference filter positioned neatly in the front cavity. This filter effectively absorbs, disperses, and mitigates vibrations while reducing resonance amplitude, ultimately optimising the output for minimal distortion and a smoother response across all three frequency ranges.

Ergonomically Designed For Snug Fit

To maintain quality standards, Tanchjim has meticulously fashioned the One using a high-quality, skin-friendly medical-grade resin material. The earphone shells are transparent and lightweight, offering a comfortable fit. To add to its visual appeal, the Tanchjim One incorporates a premium aluminium alloy rear-cavity structure.

Pretty good

I bought it on january 27, 2024 so almost a year ago, never had any issues with it, still using the same original cable, no problems whatsoever. I use it with and without DAC in both the laptop and mobile. I like the output it's clear, not so bass heavy and good soundstage. if you're looking for a bullet style IEM, this is it.

Hi there! Thank you for leaving a review for the Tanchjim - ONE.

Unbelievable clarity, neutral sound

I have a problem selecting earphones and headphones because I can only tolerate neutral tonal balance, and I love low distortion. Neutral is what headphonezone calls "flat" sound. If you browse through all the headphones and earphones here, you'll see perhaps 1% which are called "flat", and there's no way to search for the "flat" ones.

My reference earphone has been the ER4PT for the last 10+ years. The muted bass of that one doesn't bother me, but all the other qualities are unbelievable.

The Tanchjim One is amazing for me because it gives me 70-80% of the ER4 (which costs 10-12x the Tanchjim), and also because it is a very rare "flat" earphone. I've done side-by-side comparison between the Tanchjim and the ER4 and I can see that the ER4 is superior, but I can happily enjoy music with the Tanchjim. I have some high-quality Walkmans (yes, cassette) and the Tanchjim is affordable enough for me to buy one for each Walkman. The USB-C variant can be kept with each phone or laptop -- they cost very little.

Compared to the ER4, the Tanchjim has more pleasant bass, without changing the overall sound signature. It fits well into my ears with the default silicone tips -- I am lucky that way, I've never had to fiddle with eartips with any IEM or earbud. The Tanchjim cable is less microphonic than my ER4, which is nice. Compared to the Sennheiser-Massdrop HD6XX, the Tanchjim seems to have more detail, and in any case, the HD6XX works better with a headphone amp, so the use case is different.

The Tanchjim, like almost any other earphone, is very easy to drive, so there is no problem there. The USB-C and 3.5mm variants cover all the use-cases I can imagine. The fact that it has a mic allows it to be used for both work and music. I have bought a few of these little things and have given to friends. I intend to buy one or two more. I am quite sure that the Tanchjim will not be physically long-lasting, and will die after some hours of usage, and when I want to replace them, the model will probably be obsolete. So I'm stocking a couple of spares. These will be my most frequently used earphones now.

Hi there,
Thanks for taking the time to leave such a detailed and positive review for the Tanchjim - ONE!

Nostalgia!!!

I stumbled upon these while surfing for something that will serve me good and casual listening. I've OCPD and my heart skipped a beat looking at the usb c plug offered.
Fast forward 5 days and I'm not tired of grinning everytime the track changes. Paired with wavelet EQ on the phone, these are easily my drivers - the Aonic 3s I have might just not come out the drawers anytime soon.
Bass sounds almost transient compressed out of the box but not overwhelming even at 90% volume. Mid and Highs are not shrill at all, infact they are quite airy sounding like you're in the same room with the artists.
If you're into wired IEMs and like simplicity with no compromise sound in budget look no further - Tanchjim take a bow. Might just buy another pair as spare because why not!!!

Hi there! Thank you for taking the time to leave such a positive review. We are so glad to hear that the Tanchjim - ONE has exceeded your expectations and that you are enjoying the nostalgic experience it provides.
