Design and Build Quality

The Tanchjim ONE Earphones boast a minimalist design crafted from high-quality plastic with a matte silver-colored aluminium faceplate. The Tanchjim logo graces the right side, while the left side proudly displays the ONE branding. The transparent color on the inner shell elegantly showcases the dynamic driver.

The bullet-shaped design of the Tanchjim ONE Earphones ensures a comfortable fit, whether you prefer wearing them like traditional earphones or in-ear monitors. Their ergonomic design caters to various ear sizes, guaranteeing a pleasant listening experience even during extended periods.

Sound Quality

The TANCHJIM ONE Earphones offer a balanced and authentic sound profile with intimate soundstage and precise imaging. The bass is well-controlled, the midrange is clear and crisp, and the treble is smooth and leaner. The TANCHJIM ONE Earphones sound remarkably mature, exceeding expectations for their price range. This trend of delivering affordable yet high-quality sound is an encouraging sign for both newcomers and seasoned audiophiles alike.

  • Bass: The bass response of the TANCHJIM ONE is agile, impactful, and finely tuned. While the overall bass is moderate and not excessively heavy, a touch more presence in the sub-bass range could enhance the experience. The refined bass delivery prevents fatigue and avoids bleeding into the midrange and treble, making it an ideal choice for those seeking a balanced sound signature.
  • Midrange: The TANCHJIM ONE truly shines in the midrange department. With a natural and lifelike tonality, the midrange places you right in front of the artist. There's a notable absence of harshness or sibilance, and the vocals take a slightly forward position compared to the bass and treble. This mid-centric tuning ensures that you feel the texture, weight, and emotion in the artist's voice, making for a highly satisfying auditory experience.
  • Treble: The treble in the TANCHJIM ONE is detailed, although it might come across as slightly muddy in busier tracks. It lacks a bit of openness and airiness, giving the sensation of listening to instruments in a confined space. The treble offers smoothness and detail, albeit with a leaner quality. Adding a touch more sparkle and thickness to the treble region could further enhance the listening experience.
  • Soundstage and Imaging: The TANCHJIM ONE Earphones offer an intimate soundstage, enveloping you in a world of music. The imaging, while satisfactory, could benefit from improved directionality and distance perception.
