How does Air Motion Transformer work？

The diaphragm pushes back and forward from itself in a physical motion similar to that observed when an accordion is pushed in and pulled out to pump air through the reed chambers, albeit over an exceedingly smaller motion range. The result is a dipole driver with an extraordinarily rapid response rate, enabled by the extremely low mass of the polyethylene substrate and the far smaller distance it travels on each "swing" compared to a dynamic driver. In this technical respect, it shares characteristics with an electrostatic driver.

The discernible motion of each diaphragm flexure is very small, but because of the folded structure, more air is moved than would be by a conventional cone or electrostatic driver of the same plotted surface area. As a matter of surface comparison, a standard 1-inch-wide (25 mm) AMT strip has a functional driver area comparable to an 8-inch-diameter (200 mm) circular dynamic cone. The folded driver design, combined with the small motion range, means the AMT acts like a point source version of a larger driver, inherently resulting in lower sound reproduction distortion. The speed of the air as it leaves the diaphragm is approximately five times faster than the speed of the actual driver structure, hence the name Air Motion Transformer.

15.5 mm Ultra-thin Folded AMT Diaphragm

The GL-AMT16 uses a 15.5mm diameter polymer-plated metal diaphragm. Due to the unique structure of the Air Motion Transformer diaphragm, the actual area of this diaphragm can reach 55*16mm when fully expanded, which is much larger than the general planar or dynamic driver products in terms of diaphragm area. The world's first full range IEM design by an AMT transducer technology and N52 magnet deliver a rich sound stage listen to experience in the earphone market，fast and accurate transient response.

Aluminum alloy Ear Cup designed model

Gold Planar GL-AMT16 adopts aviation aluminum alloy for the shell. With the anodizing process, the surface feels smooth but also a little textured and luxurious. Even designed with this type of shell, it weighs only about 7g for each earbud. Lightweight and comfortable to wear even for a long time with less microphonics and it’s also suitable for the female who has a smaller ear.

Replaceable Acoustic Earbuds Nozzle

We understand different needs and preferences, thus we have included 5 kinds of replaceable acoustic earbuds nozzle in the package. They comply with ear tips implementation and provide a choice for lots of great sound styles. You can enjoy a favorable bass and satisfying highs.

Detachable High Quality Cable

Crystal Copper & 2 Cores Pure Silver Plated Gold Foil Cable, designed in 4.4mm/2.5mm/3.5mm Replaceable plug and 0.78mm 2Pin gold-plated connector. 1.2m cable is long and soft enough to meet most needs. Special braiding structure ensures stable transmission while also being high-end and soft. Despite that, the hot-bending pre-shaped earhook is much more comfortable than traditional earphones.

Ergonomic Design

Combined with an excellent ergonomic design, it will not feel uncomfortable to listen to music for a long time. Lightweight ear hooks keep the earphones secure, even during vigorous movement.
