Linsoul Kiwi Ears KE4 hybrid HiFi earphones Adopts diaphragm structure Equipped with dual custom 10mm dynamic diaphragms and one Knowles and balanced

[New IEM Design] KE4 has been redesigned from the ground up, combining an isobaric subwoofer system with two dynamic drivers (2DD) and two balanced armature (2BA) full-range and tweeter speakers. Two Kiwi Ears custom 10mm dynamic drivers focus on sub-bass impact and slam, making kick drums and bass guitars stand out. The RAD 33518 BA driver with a customized ventilation system ensures seamless integration of bass and midrange, delivering rich and textured vocals and instruments. The American-made Knowles RAD 33518 tweeter delivers a clean, natural-sounding treble with excellent high-frequency extension for an airy sound. [Sound quality superiority] KE4 inherits Kiwi Ears' commitment to excellent sound quality balance. The KE4 follows a new target tuning that emphasizes precise sub-bass impact, warm natural midrange, and precise treble. This sonic signature has been refined over the years and we believe it to be the most natural and appealing. This sound quality characteristic makes it suitable for all purposes, from music listening and gaming to professional stage monitoring and sound engineering. [Precision Designed] Kiwi Ears KE4 are handcrafted from start to finish. Featuring a 3-way passive crossover system and 3 independent acoustic tubes, every little bit of acoustic engineering has been done to achieve that tuning. The shell is made from medical grade resin and decorated with a hand-finished faceplate.
