6mm Low-voltage Magneto-static BM Driver

MM2 adopts a 6mm magneto-static BM (Balanced Membrane) driver customized by HIDIZS and Korea BSE, with an extremely thin and light micron-level diaphragm, which shines in transient responses to high frequencies - fast, crisp, smooth, detailed, and retains excellent layering.

Easily drive ultra-high frequencies with no need to increase voltage, low distortion, with seriously excellent resolution and extensibility.

The BM driver has an awesome overall balanced driving ability, powerful enough to control the minimum point of the diaphragm, so that different frequency bands can perform better. The original sound can be restored more harmoniously, accurately, and with rich details.

Ultra-light and ultra-thin micron-level diaphragm

Drive with ease, no need to increase voltage

Better control for minimum point of the diaphragm to reflect far better detail

Overall Enhancement In The Mid-bass Range

Hidizs PEK macromolecule polymer diaphragm+ 10.2mm dynamic driver handles bass and mids. The bass digs deeper with excellent speed, a tight response, and is punchier. The mids are smooth, detailed, and have a more U-shaped character. Vocals are sweet and instruments sound natural.

Large soundstage, outstanding imaging capabilities, excellent layering throughout, with great presence - MM2, a pair of IEMs you'll never regret having.

Beautiful Sound will Find Its Way

High-quality cables are the essential part of professional HiFi earphones. Hidizs MM2 comes with high-purity oxygen-free copper (OFC) and high-purity silver wire, twisted from 60 strands, respectively. Silver wires for a crisp and clean sound. Copper wires for soft and smooth audio performance. Both contribute to the improvement of your listening experience.

Standard 0.78mm 2-pin Design

In addition to the different sound styles brought by the 3 detachable tuning valves, MM2 retains a standard 0.78mm 2pin design to allow for the use of cables with the same specifications, either to further upgrade the sound or experience more listening experiences created by different cables. The cable sockets were upgraded to gold-plated materials to ensure more stable audio signals transmission.
