5 source(s) feeding this product's score.
Video reviews we found, each condensed to its verdict. They do feed the HearWiki score, at a measured weight below what a published written review carries.
10:50The reviewer finds the KZ D-Fi to be a well-tuned, neutral-sounding IEM with a warm touch, good bass control, forward mids, and smooth treble. It offers excellent value for around $21, though the stock cable's angled connectors caused fit issues for the reviewer. The tuning switches have minimal effect, and while it competes closely with the 7Hz Salnotes Zero and KZ ZVX, the reviewer personally prefers the ZVX for its slightly more fun sound.
30:49The reviewer praises the KZ D-Fi as a solid evolution of the ZVX, highlighting its excellent build quality, comfortable fit, and versatile tuning options via switches. They find the sound signature neutral-dark with bright treble, offering good dynamics and detail, though they note some sharpness in the upper frequencies and a preference for the switch version's flexibility. Overall, they consider it a great value for the price, with minor caveats about treble sensitivity and cable quality.
21:33The reviewer finds the KZ D-Fi to be a well-tuned and refined single dynamic driver IEM, praising its switchable tuning options and the successful combination of driver, shell, and tuning that finally delivers a clean, Harman-like sound. They note it lacks the traditional KZ bass-heavy signature, but consider it a strong value at its price, with minor nitpicks about mid-bass presence and the lowest switch setting. The reviewer is cautious about calling it an endgame due to KZ's frequent product releases.
6:27The reviewer finds the KZ D-Fi to be an excellent budget IEM, offering impressive sound quality and a useful tuning switch system for just $22. While the bass and highs have some limitations, the vocal clarity and overall value make it a strong recommendation for beginners.
