Tanchjim MINO
Tanchjim MINO brings a clean, vocal-forward wireless presentation with tight bass, natural mids, and smooth, sparkling treble. As Giz Audio notes, its clear separation and easygoing balance make it unusually polished for an affordable TWS, while the app’s 10-band EQ lets listeners tailor the sound. Secure, compact shells and long battery life complete a versatile everyday listen.

What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 86/100
Reviewers find the MINO unusually well tuned for a budget true-wireless set, combining generally clean bass, present vocals and a smooth-to-bright upper range. Its strongest traits are its coherent all-round tonality and clear presentation, while limited depth, only moderate layering and some variation in perceived bass weight keep it from feeling fully high-end.
Bass
86/100
Bass impressions vary with tuning mode and listener preference: one reviewer finds it polite or lean, while another hears substantial mid-bass and sub-bass rumble. Across the reviews, it is praised for clean control, satisfying thump and good transition into the mids, though it does not deliver the slam of similarly priced wired IEMs.
Midrange
88/100
Vocals are consistently described as clear, natural and well positioned, with female and male voices receiving particular praise. The upper mids can bring vocals forward and the lower mids may occasionally sound leaner than ideal, but reviewers do not find the presentation seriously unbalanced.
Treble
86/100
The MINO offers audible sparkle, expressive treble and commendable transient decay for its class. Its upper-mid energy can make some material sound bright or slightly aggressive, although reviewers generally report that it avoids fatigue, harshness and sibilance.
Resolution Separation
86/100
Several reviewers praise the MINO's clarity, detail retrieval and instrument separation as standout qualities for an affordable TWS. One reviewer considers resolution somewhat rounded and consumer-grade, so it is more refined than exceptional in dense or demanding material.
Soundstage Imaging
82/100
Stage width and left-to-right positional cues are regarded as good, with some welcome sense of depth and dimension. The image remains mostly inside the head, however, and multiple reviewers note restricted forward depth and layering.
Dynamics Coherence
87/100
Kick drums have satisfying impact, and reviewers hear clean separation from bass through the midrange and treble. The tuning is described as balanced, cohesive and easy to listen to across genres, even if its more neutral bass setting can feel restrained for listeners seeking greater energy.
FIT COMFORT ISOLATION PERFORMANCE 86/100
The compact housings are broadly praised for staying secure and remaining comfortable through long sessions and exercise. Fit may require a small adjustment to achieve the best seal, while noise reduction is only moderate despite the ANC claim.
Seal Stability
88/100
One reviewer says a minor adjustment can be needed to obtain a proper seal. In contrast, another finds the compact earpieces snug and stable during running, workouts and extended use, suggesting reliable retention for most users.
Comfort
91/100
The strongest fit feedback is highly positive: one reviewer wore the MINO for more than four hours, including exercise, without discomfort or movement. The compact shell design appears to suit sustained casual and active listening well.
Isolation
76/100
Passive isolation is described as decent, but reviewers can still hear outside noise when music is not playing. The active noise cancellation also disappoints relative to its claimed figure and does not block a large amount of environmental sound.

Build Accessories
87/100
The MINO includes a compact plastic charging case with a transparent lid and rounded styling, plus four sizes of silicone tips, ten replacement nozzle filters and a USB-C cable. The accessory selection is genuinely useful for fit and upkeep, while reviewers provide little long-term durability evidence and the construction is primarily plastic.
Value for Money
90/100
At roughly $42, reviewers repeatedly frame the MINO as a budget TWS with notably strong sound for the money, and one calls it brilliant at that price. It is not portrayed as an uncontested value leader, but its refined tuning, useful included tips and longer quoted battery life than the compared Space Travel make it a compelling affordable option.
