Utilizing Three Leading Technologies

IT01S is the first IEM utilizing high Tesla Magnetic Flux, Carbon Nanotube diaphragm, and DLC coating together. These are all leading technologies for dynamic drivers. Therefore, we decided to give this dynamic driver the name-DiNaTT™ (DiNaTT™ means Diamond-like coating, DLC, on a domed Nanotube driver, Tesla Magnetic Flux technology).

Carbon Nanotube Dome Diaphragm and Diamond-like Carbon Coating

The DiNaTT has the world’s thinnest Carbon Nanotube dome diaphragm at 3.8µm. Being ultra-thin means the diaphragm can be driven with ease. It also has the advancements of Carbon Nanotube’s stiffness in combination with DLC Coating. This extends the frequency range and allows for excellent dynamic response.

The DiNaTT driver has a Diamond-like Carbon Coating on the dome, this gives the stiffest dome possible. The stiffer the dome, the better the transient response, stability and improved treble range.

Tesla Magnetic Flux

With a high Tesla Magnetic Flux, the 3.8µm diaphragm is driven with ease. This contributes to an improvement to resolution, bass, dynamic and speed.

Precision Components and Electroplated Shell

The IT01S nozzle has a removable screen Now cleaning the screen is easy. In the addition the nozzle is made of 304 Austenitic stainless steel (nonmagnetic).

An Ergonomically Designed Shell Provides a Great Concha Fit


The IT01S comes with a 5N Mono Crystal Copper cable with a silver-plated shield, MMCX 2.5mm balanced connection, and a 2.5 TRRS to 3.5 TRS cable adapter.
