10 Balanced Armature+2 Electrostatic Drivers

The Maven Pro uses electrostatic drivers for ultra-high frequency extension in addition to the traditional balanced armature drivers. The frequency response range can reach up to 70kHz. Compared to the Maven, the Maven Pro has an adjusted crossover structure and driver configuration, which improves the bass response significantly. The Maven Pro no longer utilizes open-back balanced armature drivers but instead boasts two additional electrostatic drivers to improve the speed further and vastly extend the response range with the distortion rate controlled to the lowest level.


4-way crossover technology

The Maven Pro uses a 4-way crossover, 4-tuning tunnels design initially used in the Mentor series. Each frequency range has its own tuning tunnel to fully isolate between frequency sectors. A metal sound tube is connected at the end of the sound tunnel to ensure that the sound tube will not be squeezed out of shape and to maintain the consistency of sound transmission. Customers can fully experience the beautiful sound quality and premium texture that the IEM provides.


Luxurious Texturing

The brand new sapphire blue shells are incredibly dazzling and charming. Titanium provides extremely high sound insulation to reduce the mutual interference of drivers.The Maven Pro housing is printed in Medical-grade titanium alloy for high accuracy. 4 times the density of a traditional resin case. 15 times the strength of the traditional resin case, resistant to drops and compression. Professional engineers have assembled, build, and polished each and every single unit by hand. The internal acoustic cavity is designed with a high-precision 3D Printing process.


Excellent Cable

The Maven Pro comes with an UM Copper M2 headphone cable. The M2 contains OCC copper cores along with a metal Y-Splitter and chin-slider, providing excellent cable flexibility. Termination available in 2.5mm, 4.4mm balanced, and 3.5mm single-end.
