Flow: The world's first Bluetooth-enabled hybrid custom IEM

The world's first* Bluetooth-equipped custom IEMs, for you.

【We are currently experiencing a high volume of orders, and delivery may take more than 2 weeks.】

"LIFEEAR Flow," manufactured with state-of-the-art optical 3D printers, overturns the conventional image of custom IEMs, offering a 2-way wired/wireless connection and high-quality sound at an accessible price.

*Custom IEMs are earphones made to fit the unique shape of an individual's ear. They offer the best fit and sound isolation, reducing fatigue during long listening sessions and providing a comfortable listening experience.

*LIFEEAR Flow has the same driver configuration as the universal type LIFEEAR Duo.

"How LIFEEAR Flow achieves same-day delivery and an affordable price."
Traditional custom IEMs were handmade by artisans from shell to assembly, requiring high costs and long production times. However, LIFEEAR has successfully modularized the electronic components using the latest 3D printing technology, achieving a significant cost reduction for custom IEM products and an innovative service of same-day delivery* (patent pending).
Furthermore, the successful modularization has enabled Bluetooth integration and provides high-quality products through standardized quality.

*World's first... According to our own research (February 2025)
*Same-day delivery... After receiving the ear impression
