A wired single-dynamic-driver IEM built around a 10 mm dynamic driver and offered in the ONE family alongside a DSP-cable version. It is aimed at budget wired hi-fi listeners wanting a compact, replaceable-cable in-ear monitor.
The HearWiki takeAI-condensed
The Tanchjim ONE is a budget-friendly single-dynamic-driver IEM that offers a well-balanced, easy-going sound signature with solid build quality for its price. It delivers a comfortable fit and good imaging, though it may lack some refinement on complex tracks and isn't the most detailed option available. While the standard wired version performs admirably, the DSP cable variant might appeal more to some listeners despite its potentially unusual tuning.
What works

- Solid imaging for the cost
What doesn't

9:18TANCHJIM ONE - THE ONE?

15:58TANCHJIM ONE Review & Comparison
The reviewer finds the Tanchjim ONE to be a well-tuned, analytical budget IEM with a V-shaped sound signature, offering strong bass and good treble extension. It is very easy to drive but can become shouty with extremely powerful sources, and while it competes well with the Tanchjim ZERO, the ZERO scales better with more power. Overall, it is a solid choice for those wanting a bassier alternative to the ZERO.
