The iBasso IT01S is the successor to the iBasso IT01; new and improved for 2019!
IT01S Audiophile In Ear Monitors
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 an 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
Cable
