A New Frontier for Dynamic Driver Technology

Beta is Twistura’s first dynamic wired in-ear monitor built around a planar glass composite diaphragm, combining an ultra-thin micron-level glass layer with a flexible surround to achieve exceptionally fast transient response, high resolution, and a balanced, musical presentation.

Planar Glass Composite Diaphragm

The rigid glass layer provides excellent structural stability while its low acoustic damping enhances clarity, producing crystal-clear highs, natural mids, and tight, controlled bass with remarkable transparency.

11mm Dual Magnetic Dual-Cavity Driver

The large 11mm dynamic driver with a dual magnetic circuit increases efficiency and control, while the dual-cavity structure improves airflow and resonance management for deeper bass and a wider soundstage.

Replaceable Nozzle Tuning System

With three interchangeable nozzles—Standard, Vocal, and Instrumental—users can easily adjust the sound signature to match different music styles and personal listening preferences.

CNC Aluminum Alloy Shell

Crafted from aerospace-grade aluminum using five-axis CNC machining, the housing offers high rigidity, reduced resonance, and a refined industrial aesthetic with long-lasting durability.

High-Purity OFC Cable with Interchangeable Plugs

The included oxygen-free copper cable ensures stable signal transmission and features interchangeable 3.5mm and 4.4mm plugs for flexible compatibility with a wide range of audio sources.

Ergonomic Comfort Fit

Designed using extensive ear-shape data, the lightweight shell follows the natural contours of the ear, providing a secure and comfortable fit for extended listening sessions.
