【Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device’s requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.
[About clocks that synchronize time via radio waves]
The function of clocks that synchronize time via radio waves only works in the Japanese area. Please be careful.
[New IEM Design] KE4 has been completely 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.
