Kiwi Ears Septet 1DD + 4BA + 1 Planar + 1 PZT Quadbrid IEM Earphone | Open Back in Ear Monitor, with Balance and Engaging Tuning, 3.5mm/4.4mm Modular Cable for Musicians Audiophiles

10mm
Dynamic Driver: The Septet employs a proven 10mm composite dynamic driver to handle the sub-bass and bass. The large diaphragm dynamic driver excels over other driver types, delivering a potent and deep sub-bass rumble down to 8Hz for a sub-woofer-like bass signature. Precisely tuned through both passive and acoustic methods, it provides powerful, rich, yet clean bass for an uncompromised listening experience.
4 Balanced Armature Drivers: Four balanced armature drivers are chosen to manage the low-mid and mid-treble frequencies. Balanced armature drivers offer articulate, accurate, and detailed sound due to their speed, granting studio monitor-like precision to your music. Two independent crossover networks are used across the four drivers, dedicating each channel specifically to the low-mid and mid-treble range for full coverage across the entire frequency spectrum while reducing harmonic distortions.
1 Micro Planar Transducer: This model includes a single micro planar transducer (MPT) driver as its ultra-treble tweeter. The newly updated MPT has significantly improved output at high-treble frequencies, which increases clarity while minimizing distortion and artifacts. The natural texture and timbre of the MPT allows a smooth treble extension up to 30kHz to reveal every micro-detail and air in the music, without harshness.
1 Piezoelectric (PZT) Driver: An updated PZT driver is included, enhancing the texture and clarity in the upper registers. Synchronized with the MPT driver, the PZT delivers extreme articulation that refines the perceived air across the entire frequency spectrum, helping to better define the resolution, soundstage, and imaging.
Open-Back IEM: This model prioritizes optimal music playback above all. For this reason, it is designed as an open-back IEM, allowing full ventilation to every driver inside. The open-back design is integral to the acoustic tuning, which permits greater airflow and responsiveness from the drivers. Additionally, the open-back design helps to enhance the soundstage and give an 'acoustic' like texture to the sound.
Extensive Engineering: It took nearly two years to design and develop this model. It uses a comprehensive 5-way passive crossover network, combined with acoustic tuning strategies and a three-bore nozzle system to deliver a balanced and optimal tuning profile. The 5-way crossover spans over 4 driver types and 7 drivers to assign the ideal frequency ranges for each driver group, minimizing total harmonic distortion while boosting output. Engaging and
Balanced Tonal Balance: This model aims for the perfect balance between musical engagement and tonal accuracy. Intended for both music enthusiasts and professional sound engineers, it 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: This model comes standard with a modular cable system, allowing easy switching between 3.5 mm unbalanced and 4.4 mm balanced plugs. The custom cable incorporates ultra-high purity copper wires for noise-free signal transduction
