Meticulously Handcrafted
ADV. M5-6D in-ear monitors are expertly handcrafted using only the bespoke and highest grade components. Each unit goes through a specific set of procedure that includes 3D printing, hand-poured mould, grinding, laser-cutting, sanding and polishing. This meticulous production procedure requires 4-6 weeks of lead-time from preparation of the material to the final assembly. Once assembled, every M5-6D goes through a rigorous quality control process by the master technician, before finally getting approved and packaged.

Proprietary Hybrid Driver Technology
The M5-6D utilizes a proprietary-tuned blend of balanced armature drivers and the latest electrostatic tweeters to express audio in an unconventional fashion. One deciding characteristic of M5-6D is its incredible bass response with a set of dedicated woofers which is intimate and powerful - ideal for rock, pop and live music to accentuate the realistic and raw soundstage. The electrostatic tweeters bring out the micro-detail so you never miss the treble nuance under the bass. The resulting audio is powerful, sibilance-free and intimate listening experience that is completely unique and distinctive.

Designed to Fit You
The M5-6D is crafted with medical-grade acrylic, which is one of the safest material to use for a wearable device that comes in contact with your skin. Universal version of M5-6D is ergonomically designed after studying the shape of thousands of custom in-ear monitors. We've taken a common denominator from all the different ear shape, and morphed them into the universal shape it is now. Furthermore, the M5-6D is also offered in custom-fit, crafted to fit only your ear, should you decide to send us your ear impression.
