Advanced Hybrid Driver Design
The Kiwi Ears Septet combines seven drivers across four technologies—dynamic, balanced armature, micro planar, and piezoelectric—to deliver an exceptional audio experience with deep bass, clear mids, and smooth treble. The open-back design and custom tuning ensure a natural and expansive soundstage for both music enthusiasts and professionals.
7 Drivers with 4 Advanced Driver Types: The Septet features an innovative hybrid setup with 7 drivers per side, combining dynamic, balanced armature, micro planar, and piezoelectric technologies. This diverse configuration ensures full-spectrum coverage with exceptional technicality, clarity, and musicality—ideal for both audiophiles and professionals.
Powerful and Clean Sub-Bass with 10mm Dynamic Driver: A large 10mm dynamic driver handles sub-bass and bass frequencies, delivering powerful, deep rumbles down to 8Hz. It’s tuned for tight, punchy impact without muddying the mids, creating a clean yet immersive low-end presentation that resembles a high-quality subwoofer.
Ultra-Detailed Treble with Micro Planar and PZT Drivers: The combination of a micro planar transducer and updated piezoelectric driver brings exceptional clarity, air, and resolution to the upper frequencies. Extending smoothly up to 30kHz, this setup enhances micro-details and spatial cues, offering a lifelike, three-dimensional listening experience without harshness.
Open-Back Design and 5-Way Crossover Network: Designed with an open-back shell and an intricate 5-way passive crossover system, the Septet allows natural airflow and precise driver control. This results in a spacious soundstage, organic tonal balance, and minimal distortion, making it equally suitable for critical listening and emotional musical enjoyment.












7 Drivers, 4 Driver Types
The Kiwi Ears Septet is our latest advancement in hybrid driver configuration IEMs. Each Septet features four different driver technologies, totaling 7 drivers per side, for a comprehensive and technical audio performance.

10mm Dynamic Driver
The Septet utilizes the tried-and-true 10mm composite dynamic driver to power the sub-bass and bass. The large diaphragm dynamic driver outperforms other driver types for a powerful and deep sub-bass rumble down to 8Hz, and delivers a sub-woofer-like bass signature. Tuned precisely through both passive and acoustic strategies, the Septet offers hard-hitting bass that is rich, yet clean, for an uncompromising listening experience.

4 Balanced Armature Drivers
Four balanced armature drivers have been selected to power the low-mid and mid-treble frequencies on the Septet. Balanced armature drivers offer an articulate, accurate, and detailed sound due to their speed, providing a studio monitor-like precision to your music. Two independent crossover networks are utilized across the four drivers, dedicating each channel specifically across the low-mid and mid-treble range for a complete coverage across the entire frequency range while minimizing harmonic distortions.

1 Micro Planar Transducer
The Septet features a single micro planar transducer (MPT) driver as its ultra-treble tweeter. The newly updated MPT has significantly enhanced output at high-treble frequencies, which elevates the clarity while minimizing distortion and artifacts in the sound. The natural texture and timbre of the MPT allows a smooth treble extension up to 30kHz to bring out every micro-detail and air in the music, without harshness.

1 Piezoelectric Driver
An updated PZT driver is featured in the Septet, enhancing the texture and clarity in the upper registers. Synched in unison with the MPT drivers, the PZT delivers extreme articulation that refines the perceived air across the entire frequency spectrum, helping to better define the resolution and soundstage and imaging capabilities.

Open-Back Design
The Septet has been designed as an open-back IEM, allowing full ventilation to every driver within. This design enables greater airflow and responsiveness to the drivers, while enhancing the soundstage and giving an ‘acoustic’ like texture to the sound. It’s an essential part of the Septet’s natural and immersive tuning.

Extensive Engineering
It has taken almost two years for our team to design and develop the Septet. The Septet utilizes an all-encompassing 5-way passive crossover network, combined with acoustic tuning strategies and a three-bore nozzle system to provide a balanced and optimal tuning profile. The 5-way crossover spans over 4 driver types and 7 drivers to assign the optimal frequency ranges for each driver group, minimizing total harmonic distortion while boosting output.

Engaging and Balanced Tonal Balance
The Septet targets the ideal balance between musical engagement and tonal accuracy. Intended for both music enthusiasts as well as professional sound engineers, the Septet features an impactful sub-bass shelf that cleanly transitions into the low-mid and mids, which is natural and free from artificial coloring. The treble range is crisp, yet maintained at a comfortable level throughout the entire curvature, allowing for an extended, yet smooth, performance across the highs.

Custom Modular Cable System
The Septet comes standard with a modular cable system, allowing easy change between 3.5mm unbalanced and 4.4mm balanced plugs. The custom cable features ultra-high purity copper wires for a noise-free signal transduction.
