Unity Micro Dynamic IEMs
Made in Canada
Achieving a perfect IEM is a matter of geometry as much as acoustics. That’s why we developed the Micro Dynamic, specifically designed for listeners with smaller ear canals and small bowl ears. It features the same 9.2 mm driver of the original Dynamic, housed in a shell that’s 30% smaller.
It also has stainless-mesh face venting to maintain the natural sound and comfort the Dynamic is known for, along with a low-profile Linum 2-pin cable. Despite its reduced size, it closely recreates the tuning, sonic performance, and detail of the original.
The standard Unity Dynamic remains the best fit for the vast majority of listeners, reflecting extensive ergonomic research across a wide range of ears. The Micro is ideal for those who consistently find earphones too large or know their ears fall below average in size. If you're unsure, we have both versions ready for your ears to try on for size and sound at Bay Bloor Radio.
Unity Dynamic makes Plunge Audio's universal-fit in-ear monitors more accessible and easier to enjoy than ever.
Designed to offer the sonic forgiveness of over-ear headphones with the intimacy of in-ear monitors, the Dynamics deliver a deep, cohesive connection to your music — whether you're on stage or just enjoying your favourite track.
Featuring the same patented, custom-inspired fit as the Unity Stage, the Dynamic also inherits that signature sense of space and liveliness from a filterless, open nozzle design. The meticulously sourced dynamic driver brings a deep sub-bass response while maintaining present mids and well extended highs. All while our proprietary tuning and venting system adds air and liveliness around the sound — bringing every stage, session, and song to life.
With the most compact version of our patented shell design (Canadian Design No. 221187), you can experience a fit and seal akin to Custom IEMs, while enjoying the convenience of a universally-fitting product.
Stage: Made for a Warm, Smooth Experience
The Unity Dynamic is for artists and music lovers who want the warmth, punch, and depth of over-ear headphones in an IEM format. Perfect for bassists, drummers, and acoustic players, it delivers a spacious, musical feel with deep lows and smooth highs —without losing the intimacy of in-ears. It’s forgiving, musical, and a favourite for listeners who want less edge in their ears and more vibe in their mix.
Powerful Dynamic Driver
Our specially selected dynamic driver offers a cohesive sonic profile full of depth and clarity. Featuring our signature tubeless, damperless design, the driver sits in perfect alignment with the nozzle and canal opening to maximize its potential output, while the acoustic channel is designed to preserve the character of the driver itself.
Cutting Edge Tuning
The Unity Dynamic features a proprietary tuning method and a unique venting system that utilizes an experiential approach through the tragus. This design delivers rich bass and a subtle high-frequency boost, and ensuring a full, immersive sound—even in venues with subpar acoustics.
Custom-Inspired Fit
Created with the help of thousands of sets of impressions, Plunge's patented shell design is derived explicitly from the anatomy of the human ear. They feature the shape, canal entrance, and angle common to the vast majority of human ears. The organic nature of Unity Universal IEMs leads to a superior fit, seal, and sound — a universal design that's closest to custom molds.

What's in the Box
Hardshell Case
The hardshell case features an ultra-secure magnetic closure while maintaining a low profile for easy pocket storage. It’s lightweight yet protective, and the integrated loop allows you to attach the included carabiner for added convenience. Plus, you can add your name to the tag on the back to keep track of who's is who's.
Linum 2-Pin Cable
The 2-pin (0.78mm) Linum cable is thinner and lighter than our standard Plunge cable, designed to disappear when worn. Its soft, flexible build offers a barely-there feel — ideal for performers who value comfort, freedom of movement, and a clean, low-profile setup on stage. Finished in a discreet black, it keeps your rig looking streamlined and professional, even in high-visibility environments. Built with higher-purity silver-plated conductors, the Linum 2-Pin Cable delivers a clean, reliable signal. Its fully integrated, injection-moulded construction encases the cable from end to end, helping enhance long-term durability and reduce potential weak points.
