About Kiwi Ears
New Driver Architecture
The KE4 II features a newly developed 1 planar + 2BA + 1DD hybrid driver configuration designed for improved resolution, layering, and tonal balance.
More Information...The KE4 II has been engineered from the ground up, utilizing a completely new driver configuration that achieves greater resolution and midrange texture. A single 10mm biocellulose dynamic driver subwoofer delivers precision sub-bass and bass impact. A custom dual balanced armature drivers focus on layered and articulate mids and lower-trebles, while a single custom ultra-treble tweeter brings out airy micro-details. Compared to the original KE4, the new driver configuration optimizes driver load, particularly in the mids and trebles, enhancing technical performance and timbre.
A Refined Take on Modern Sound Signature
The KE4 II balances tonal accuracy and musicality with a refined tuning approach, delivering controlled bass, natural mids, and smooth high-frequency detail.
More Information...The KE4 II was tuned following a new tonal ideology. Based on modern target preference curvatures, The KE4 II refines the sound signature to balance neutrality with musicality. The lows feature a dedicated 8dB sub-bass shelf that cuts off precisely at 200Hz, providing enough bass rumble for all genres, while keeping the midrange free from bloating or muddyness. The midrange is completely flat from 200Hz to 1kHz, allowing a studio monitor presentation of vocals and instruments. This allows the music to be heard as it was recorded, without any artificial colorations to the sound. The treble peaks exactly at 3kHz, following the perceived hearing compensation for the ear anatomy. The ultra treble has been tamed to allow a more natural and fatigue-free listening while maintaining a spacious soundstage.
Optimal Sound for Every Genre
With its balanced tonal response, the KE4 II is designed to adapt to different musical styles while maintaining a cohesive and natural sound signature.
More Information...The KE4 II sits at the tonal balance that is perfect for every musical genre. Whether it is pop, rock, hip-hop, or classical music, the secret to the KE4 II’s performance lies in its sound signature. Each musical genre is presented as it was intended, allowing the KE4 II to sound incredible, no matter what song is playing. Moreover, the KE4 II is perfect for all usage scenarios, including stage performance, sound engineering, musical enjoyment, and gaming.
