Unlike in-ear or over-ear headphones, the Truefree B1 wireless earbuds sit securely without blocking your ear canals, keeping your ears open for natural awareness. The sleek, water-drop design adds a modern edge - ideal for workouts, travel, and daily use.
- [Ultra-Secure & Lightweight Fit] - Engineered for stability, the C-shaped bridge structure and anti-Z-shaped hooks provide a snug, slip-free fit. Crafted from soft, skin-friendly silicone and weighing just 5g per earbud, the Truefree B1 open-ear earbuds have undergone 300,000 wearability tests to ensure all-day comfort without pressure or irritation.
- [Immersive Spatial Audio with Deep Bass] - Powered by 10.8mm dual magnetic drivers, these clip-on earphones deliver twice the richness of standard drivers. The high-carbon fibre diaphragms and dynamic balancing algorithms produce crystal-clear highs, deep bass, and a 360° panoramic surround sound effect, mimicking a cinematic audio experience.
- [25 Hours Battery Life & Fast Charging] - Stay powered throughout the day with 5.5 hours per charge and up to 25 hours with the compact USB-C charging case. Need a quick boost? Just 10 minutes of charging provides 1 hour of playback. With IPX4 water resistance, these earbuds can handle sweat, rain, and outdoor adventures.
- [Minimum Sound Leakage & Bluetooth 5.4] - Truefree’s Audio Technology 2.0 reduces sound leakage by up to 98%, ensuring private listening with directional sound holes and reverse sound wave noise cancellation. Meanwhile, Bluetooth 5.4 provides a fast, stable connection for seamless music and calls.
- [Customisable Sound & Smart Features] - Personalise your listening experience with the Truefree App. Adjust EQ presets to match your preferences, modify touch controls (including volume adjustment), or reset your earbuds - all through an intuitive, easy-to-use interface.
