Four-driver hybrid architecture with dynamic and balanced armature drivers for precise audio reproduction.
Micro-perforated pressure balance system ensures comfort and optimal acoustic performance.
High-purity Juzear Flame cable enhances signal integrity and connectivity versatility.
Juzear has unveiled the Defiant, a pair of hybrid in-ear monitors developed in collaboration with renowned audio authority Z Reviews. The Defiant stands out with its sophisticated four-driver configuration, featuring one dynamic driver and three balanced armature drivers per earpiece. This setup is managed by a three-way crossover equipped with four acoustic tubes, ensuring precise frequency division and minimal distortion across the audio spectrum.
The construction of the Defiant incorporates a micro-perforated pressure balance system within its DLP 3D printed ear shells, designed for optimal acoustic performance and a comfortable, secure fit. The 10mm dynamic drivers boast a composite diaphragm made from carbon and polyurethane, delivering robust bass response that remains tight and controlled. Complementing this are the three customized balanced armature drivers, which provide clear midrange and crisp high frequencies, enhancing the overall sonic clarity and depth.
Technical specifications highlight the Defiant's impressive capabilities, including an impedance of 32Ω, a sensitivity of 109dB±1dB, and a frequency response range spanning from 20Hz to 20kHz. The in-ear monitors also feature a low total harmonic distortion plus noise (THD+N) of ≤0.8%, ensuring high-fidelity sound reproduction. Connectivity is versatile with a 0.78mm 2-pin connector system and interchangeable termination plugs for both 3.5mm and 4.4mm outputs, catering to a wide range of devices.
Included with the Defiant is the Juzear Flame cable, constructed from high-purity 6N SPOCC+SCCW copper with 70 strands per conductor, totaling 280 strands. This premium cable offers both a non-symmetrical mini jack and a balanced Pentaconn plug, providing flexibility and superior signal integrity. Available in Rainbow and Jade Green color options, the Defiant combines aesthetic appeal with technical excellence, retailing at $99.99.
Overall, the Juzear x Z Reviews Defiant IEMs deliver a compelling blend of advanced engineering and refined audio performance. Their hybrid driver architecture, meticulous acoustic design, and high-quality materials make them a notable addition to the in-ear monitor market, appealing to audiophiles seeking both precision and style in their listening experience.
