Description / iBasso Cookie TI IEM
TC4 Titanium Alloy Shell
The shell is crafted from TC4 titanium alloy, a material known for its high strength-to-weight ratio, corrosion resistance, and long-term durability. TC4 is widely regarded as an industrial standard for titanium alloys, offering both mechanical integrity and refined aesthetics.
Titanium’s rigidity helps minimize unwanted enclosure resonance, allowing the driver to perform with greater stability and consistency.
Available in Glossy and Matte finishes.


Magnesium-Aluminum Alloy Dome Diaphragm
At the core of Cookie Ti is a magnesium-aluminum alloy dome composite diaphragm. This material is both extremely light and highly rigid, enabling faster transient response and improved clarity across the frequency range.
High stiffness helps suppress local vibration and redundant noise, reducing distortion and preserving detail even at higher sound pressure levels.
1.6 Tesla Dual Magnetic Circuit System
To fully drive the magnesium-aluminum alloy diaphragm, Cookie Ti employs a dual magnetic circuit system delivering 1.6 Tesla magnetic flux density. This high-energy magnetic field ensures accurate diaphragm control, improved efficiency, and stable performance across dynamic passages.
Dual Helmholtz Resonators
Cookie Ti features a dual Helmholtz resonator structure, designed to smooth the internal sound path and suppress standing waves. Compared to single-resonator designs, this configuration reduces resonance, lowers distortion, and enhances transient performance.
Interchangeable Nozzles
Cookie Ti includes gold-plated brass and stainless steel nozzles.
Different nozzle materials subtly alter the sound signature, allowing you to fine-tune the presentation to your preference.
