【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.

[Four types of drivers, 5 drivers on each side] Kiwi Ears Quintet uses four types of drivers: 1 diamond-like carbon (DLC) dynamic driver, 2 balanced armature (BA) drivers, 1 planar magnetic driver, and 1 piezoelectric (PZT) bone conductor. With a total of five drivers per ear, Quintet delivers extremely high-resolution audio comparable to professional studio monitors. The subwoofer uses a large 10mm DLC driver that takes advantage of DLC's high responsiveness and tensile strength, and outputs impactful bass while attenuating at high speed. 2 Knowles' Balanced Armature Driver delivers natural, high-resolution midrange and is a prime example of why balanced armatures are loved in the industry. We are pleased to announce that AMT Acoustic's planar tweeter driver is now available in Quintet. [Kiwi Microplanar Transducer (MPT) Driver] Achieving high quality ultra-treble has been a challenge in the IEM industry. Although BA drivers are compact, they have poor ultra-treble extension and have limitations in output and sound quality. EST (electrostatic) drivers are difficult to use in multi-driver setups because their output is very low and gets drowned out by the volume of other drivers. Additionally, EST drivers can have a very metallic sound at high voltages, which can give off an unnatural presence. That's why Kiwi Ears has developed a new ultra-treble tweeter with an incredible output of 118dB despite its tiny module size of just 5mm. The Kiwi MPT driver efficiently generates sustained high frequencies from 4kHz to 40kHz. In general BA drivers and EST drivers, the output in the high frequency range decreases after 8kHz. [Planar Drive Diaphragm, etc.] A new driver technology in the IEM industry, this new tweeter features a classic planar magnetic driver circuit, but with a smaller footprint for use in hybrid designs. With an extremely low noise floor and high output capacitance, this planar magnetic driver delivers crisp, detailed treble frequencies unlike the typical BA or EST (electrostatic) tweeters used in most IEMs today. Finally, piezoelectric drivers were utilized to achieve ultra-treble fine detail and airiness. In R&D tests, the presence of PZT drivers significantly improved audio resolution, texture, and soundstage. [Natural Sound] Kiwi Ears Quintet inherits the natural and balanced tuning characteristics of Kiwi Ears. To meet the demands of professional musicians and audio engineers, the Kiwi Ears Quintet's sound quality is now similar to recording room ear monitors. Kiwi Ears Quintet adopts a 3-way structure to achieve complex separation, effectively reducing THD+N. Kiwi Ears Quintet's bass is now limited to the sub-bass frequency range. The peak value from 20Hz to 200Hz is 8dB. From 200Hz to 800Hz, there is only 1dB of distortion. The treble already matches the contour of the human ear, with a peak value of 7dB at 2.5KHz, and slowly decays from 10KHz. This precise process allows us to recreate every detail. [Superior Audio Cable] The Kiwi Ears Quintet cable is a 4-core 7N oxygen-free copper (OFC) cable that can enhance the sound. Ultra-light materials are utilized to create this cable. This cable is designed with an internationally universal 0.78mm2pin connector and is compatible with most earphones on the market. In addition, a 3.5mm stereo plug is designed for use with smartphones, laptops, computers, and other devices. Product Specifications [About Kiwi Ears] At Kiwi Ears, we have created a combination of technological innovation and precise tuning strategies, driven by superior audio reproduction. Especially considering the working environment of musicians and engineers working in recording rooms, we have developed top-of-the-line in-ear monitors that can accurately reproduce audio signals without compromise. Our professional engineers are not satisfied with ordinary things and make all screwdrivers by hand. Users can enjoy music to the fullest without worrying about what's going on in their ears. We are Kiwi Ears. Bringing audio enthusiasts an unprecedented music experience.

The Kiwi MPT driver efficiently generates sustained high frequencies from 4kHz to 40kHz. In general BA drivers and EST drivers, the high frequency output decreases after 8kHz. However, MPT drivers can maintain the same constant sound pressure at 14kHz as at 4kHz or 8kHz. This makes the MPT driver similar in output to other drivers such as BA and DD, giving it great flexibility in tuning. Additionally, MPT drivers have a much more natural tone than EST or BA drivers, so they blend better into your mix.
