Kiwi Ears Quartet

Several reviewers praise a hard-hitting, textured and energetic low end with substantial mid-bass slam and audible sub-bass rumble. However, the strongest bass settings can become bloated or overwhelming, with some reviewers hearing upper-bass bleed, sluggishness, or one-note behavior on certain material.

Positive reviews describe the mids as clear, lush and velvety, with rich male vocals and smooth, non-sibilant vocal reproduction. Others find the bass emphasis pulls attention away from the midrange, while upper mids can sound thin, recessed, or disconnected from the warmer lower mids.

The treble is often described as smooth, relaxed and suitably airy, helping make the Quartet comfortable for extended listening and movie use. Extension is repeatedly judged behind competing sets, and dissenting reviewers report a pronounced 6-8 kHz peak that can sound splashy, metallic, piercing or fatiguing.

Prime Audio Reviews and Fresh Reviews hear strong detail retrieval, a dark background and convincing separation for music and competitive gaming. In contrast, other reviewers find detail merely adequate and report that busy passages can become fuzzy or masked when the elevated bass takes over.

Spatial performance is generally described as intimate to moderately sized rather than expansive, with reasonable width and depth. Fresh Reviews particularly praises depth, verticality and positional cues for gaming, but other reviewers hear average depth, occasional three-blob imaging, or a two-dimensional presentation.

The Quartet's punchy bass gives drums, games and films lively impact, and some reviewers find the switch settings capable of producing a more dynamic balance. The main reservation is integration: critical listeners hear the drivers as unevenly blended, with bass-to-midrange bleed and artificial upper-range timbre reducing coherence.

Most reviewers report that the shells fit well, and one reviewer found the small SpinFit CP100 especially effective with no pressure buildup. Still, PortaFi notes the relatively short nozzles may require tip rolling, while Prime Audio Reviews found the included tips too small for their ears.

Comfort is a clear strength: reviewers call the shells lightweight, ergonomic and exceptionally comfortable. Reports include three-hour movie sessions and four-to-five-hour wear with no notable fatigue or ear-canal discomfort.

Reviewers find isolation good enough for commuting and public transport, with one estimating meaningful attenuation of outside noise. Another reviewer considers it slightly below average, so it is helpful rather than an especially isolating stage-monitor design.

The lightweight resin shells are widely regarded as attractive, nicely finished and well built, while the package includes a protective case, three tip styles and a switch-adjustment tool. Opinions on the stock cable are divided: several reviewers consider it excellent and tangle-free, but one finds its weak earhooks and cheap feel disappointing for the price.

At roughly $109-$110, multiple reviewers regard the Quartet as an unusually compelling bass-oriented option, with recommendations ranging from excellent budget all-rounder to giant killer. Its value is strongest for listeners wanting powerful low end, smooth listening and gaming or film capability, although the more critical sound impressions mean it will not suit every tonal preference.
