[Open-Ear Design with Secure Fit] – The Truefree B1 wireless earbuds feature an innovative open-ear clip-on design that rests outside your ear canal, offering breathable, pressure-free comfort. Crafted with skin-friendly liquid silicone hooks and weighing just 5g per earbud, they provide a secure, slip-resistant fit ideal for all-day wear.
[Immersive Spatial Audio with Deep Bass] – Powered by 10.8mm dual magnetic drivers, the Truefree B1 open-ear earbuds deliver twice the richness of standard models. High-carbon fiber diaphragms and dynamic balancing tech produce crystal-clear highs, deep bass, and immersive 360° panoramic surround sound.
[All-Day Battery Life & Water Resistant] – Get up to 25 hours of total playtime (5.5 hours per charge + 19.5 hours with the case). A quick 10-minute charge gives 1 hour of use. With an IPX4 rating, these clip-on earbuds resist sweat and light rain — perfect for workouts, commutes, or outdoor use.
[Minimal Sound Leakage & Bluetooth 5.4] – Truefree’s Audio Technology 2.0 uses directional sound holes and reverse sound wave cancellation to reduce sound leakage by up to 98%. Bluetooth 5.4 ensures fast, stable pairing and low-latency audio across all your devices.
[Custom Sound with the Truefree App] – Take full control of your listening experience. Use the Truefree App to adjust EQ presets, customize touch controls (including volume), and reset your earbuds with ease through an intuitive interface.
