Radius TWF31/TWF41 IEM

Dual Drivers, Detachable Cable

From Japanese audio company Radius, the TWF31 IEM stands out for its Dual Diaphragm Matrix configuration: two individual drivers on each side, one for high-frequency reproduction and the other for midrange to low frequencies. Unlike traditional balanced-armature configurations, the TWF31’s coaxial structure places both the dynamic and piezoelectric ceramic drivers on the same axis, resulting in clear treble and extended bass. The newly developed Deep Mount earpiece provides noise isolation and a secure, comfortable fit, while the detachable MMCX cable allows you to swap in a replacement whenever you please.

Note: This drop’s base price is for the Radius TWF31 IEM. At checkout, you’ll have the option to upgrade to the TWF41, the company’s flagship model (+ $100).
