Linsoul Kiwi Ears Septet 1DD + 4BA + 1 Planar + 1 PZT Quadbrid IEM Earphone

：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. ：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. ：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. ( ) ：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. - ：The Septet prioritizes optimal music playback first and foremost. For this reason, the Septet has been designed as an open-back IEM, allowing full ventilation to every driver within. The open-back design is integral to the acoustic tuning engineered for the Septet, which allows greater airflow and responsiveness to the drivers. Additionally, the open-back design helps to enhance the soundstage and give an ‘acoustic’ like texture to the sound. ：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. ：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. ：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.
