Kiwi Ears x Crinacle: Singolo
With a secure seal, the Singolo’s 11mm driver delivers controlled sub-bass, clear vocal focus, and airy treble energy. The Honest Audiophile found its bass textured and composed, while its low-distortion single-driver design remains clean at volume. Tip rolling is essential, but the result can be a pleasant, lightly bass-boosted listen with capable layering.

Pros
Controlled, extended sub-bass offers pleasing texture, rumble, and impact without overwhelming the mix.
Slightly forward mids give vocals and instruments clear presence without sounding aggressively shouty.
Low distortion from the single dynamic-driver design supports clean playback at higher volumes.
Layering and front-to-back placement are competent, keeping elements reasonably separated.
Cons
Included tips can provide an unreliable seal, causing bass loss, shallow fit, and major tonal changes.
Upper mids and lower treble can sound glarey, shrill, or harsh for some listeners.
Accessories are sparse, with no carrying case included.

What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 79/100
The Singolo’s intended neutral-with-sub-bass-boost balance works well for one reviewer, who found it pleasant, controlled and competitive at its price, but two others found its upper-frequency tuning harsh or intolerable. A secure seal and alternative ear tips appear especially important: poor fit was associated with thinness, lost bass and a hollow presentation.
Bass
83/100
With a proper seal, reviewers hear nicely extended sub-bass, controlled mid-bass and enjoyable texture without excessive dominance. However, impact is described as softer than ideal, and one reviewer found the bass detached from the mix or entirely lost when the seal failed.
Midrange
79/100
The positive account describes slightly forward but non-shouty mids with good vocal presence, natural-ish tone and timbre. Other listening reports found the middle frequencies thin and hollow, while The Headphone Show identified excess glare around 4kHz.
Treble
74/100
Treble has air and energy for the reviewer who enjoyed the Singolo, though even that account calls the upper range slightly spicy. More critical reviewers repeatedly report shrillness around 6–7kHz and a crisp, granular, harsh quality that can make the presentation fatiguing.
Resolution Separation
80/100
Separation is considered decent for the price, and the Singolo can keep elements reasonably defined rather than turning dense passages into a blur. Detail retrieval and resolution are otherwise characterized as average for its class, with tonal issues sometimes obscuring distinctions between instruments.
Soundstage Imaging
78/100
One reviewer found useful depth, layering and a convincing sense of front-to-back placement despite limited width. Another found the stage tight and largely confined between the ears, so spatial performance is more competent than expansive.
Dynamics Coherence
81/100
The single dynamic-driver design is reported to maintain low distortion, including at higher volume, which supports a clean overall presentation. Still, the low end is described as soft in impact and quick in decay, limiting its sense of physical punch.
FIT COMFORT ISOLATION PERFORMANCE 77/100
Fit is the Singolo’s clearest practical concern. Two reviewers struggled to achieve or retain a seal with supplied tips, with major consequences for bass and tonal balance, though another had stable, comfortable long-session wear after selecting the Velvet tips; passive isolation is only moderate.
Seal Stability
70/100
Both inToit Reviews and The Headphone Show had difficulty getting a reliable seal from the included tips; one described shallow fit that could unseat with small movements. The resulting bass loss and tonal change are substantial, although Velvet tips gave another reviewer a better, more secure fit.
Comfort
85/100
One reviewer found the earpieces comfortable for several hours and said they stayed put once properly inserted. The large, chunky nozzle and other reviewers’ seal difficulties mean comfort and fit may be notably ear-dependent.
Isolation
78/100
Passive attenuation is described as adequate rather than strong, blocking roughly half of outside noise in one reviewer’s estimate. The reviews provide no indication that it is designed for especially demanding isolation duties.

Build Accessories
80/100
The supplied cable receives clear praise for being well behaved, resistant to tangling and pleasant in use. The package is otherwise sparse for the price, with two silicone-tip types but no carrying case, while the nozzle is reported to be notably wide and may complicate tip fit.
Value for Money
80/100
At around $80, one reviewer considers the Singolo appropriately priced and competitive within its class. In contrast, another concludes that its fit-dependent sound and persistent harshness leave it poor value even at $79, making its appeal depend heavily on whether its tuning and fit work for the listener.
