Driver / Sound

1-stadium dynamic driver + 2-balanced armatures


4.4mm / 3.5mm / 2.5mm jack



Pinnacle of TOTL Audio Experience
ADV. Turbo has been designed and developed for the pursuit of perfect, harmonious, realistic and holographic sound. Every nuance and subtle characteristics are expressed in astonishingly faithful sound reproduction through meticulous combination of proprietary driver technology, inner acoustic chamber and electronic design. The Stadium perpendicular dynamic driver, combined with the custom dual balanced armatures through active cross-over is housed in an indestructible stainless steel housing with zero unwanted resonance and distortion.

World's First Stadium Driver Technology
The Stadium perpendicular dynamic driver is exclusively developed by ADV. to feature in the Turbo for the first world debut. The Stadium driver brings the best qualities of a dynamic driver - transient and wide-frequency reproduction, accurate and natural timbre - into more compact and efficient packaging. The special stadium-shape diaphragm delivers the same vibration characteristics and volumetric air flow equivalent to 10mm circular diaphragm with a cross-sectional area of less than 7mm. Mounted perpendicular, the moving air is more effectively calibrated and controlled for precision audio tuning. The Stadium driver is designed to be embedded in custom-fit in-ear monitors that require the widest frequency reproduction in the smallest package. It is first showcased in the Turbo to exercise its technical prowess.

3D-printed Stainless Steel Housing
The Turbo is crafted with a combination of innovative production techniques to achieve its design concepts that encompass tight (±0.1mm) production tolerance and complex design ergonomics. Manufacturing of the complex main housing is only achievable through 3D-printing in stainless steel, which is then polished, sand-blasted, PVD-coated for assembly with other parts that are CNC-machined. The resulting acoustic chamber is vibration and resonance-free, providing an ideal foundation for the perfect audio reproduction.

Concept and Design Inspired by Turbocharger
The design inspiration comes from a turbocharger in an automotive engine. We've taken the concept and design cues from that part of an engine which transforms the engine's original power output in a substantial way just like the Turbo transforms the way music is heard in an unprecedented way. We've found this concept analogy striking and memorable. Our passion converges in a meaningful way with the Turbo and we are proud to present it to the world.

Introducing Eartune Fidelity UX
The Turbo comes equipped with a set of Eartune Fidelity UX medical-grade silicone ear tips. The Eartune Fidelity UX ear tips are designed to provide increased grip and seal using the most allergen-free, safe-for-body material possible. Various other materials / shapes / sizes ear tips - Eartune Fidelity U, Eartune Fidelity UF memory-foam ear tips - are included offering the ultimate universal-fit for individual ears.

Versatile Balanced Connectivity
The cable for the Turbo is quad-braided silver-plated copper terminated in 2.5mm balanced jack, designed for clean signal transmission. 4.4mm balanced / 3.5mm balanced / 3.5mm single-ended adapters are included in the package for versatile connectivity with your favorite sources.
