The "air conduction" mechanism delivers sound that floats in front of your ears, eliminating vibration and pressure, and the claustrophobic feeling of in-ear earphones. The absence of a band around the back of the head creates a comfortable fit, enhancing immersion. The lightweight design, weighing just 11g, makes them easy to wear and doesn't put pressure on the ears. They're ideal for those who find it difficult to wear traditional earphones. The open design prevents them from falling out, allowing you to enjoy music while working. Dual-microphone call noise-canceling technology provides a comfortable calling experience. Effectively reducing environmental noise ensures clear calls even in noisy environments. These features make them ideal for those who frequently need to communicate with others or for situations where earphones are required. (Note: Bluetooth signal interference may cause one earbud to fail to connect, rendering the other earbud unusable. This issue can be resolved by resetting the earbud.) 🎵【16.2mm Dynamic Driver & Bass Reinforcement Algorithm】TRUEFREE O1 supports AAC/SBC codecs, delivering high-quality sound. Enjoy clear, immersive sound for all your music, movies, podcasts, and more. Furthermore, the earphones feature a 16.2mm dynamic driver. The wide frequency response faithfully reproduces the subtle nuances and depth of your music. Enjoy a balanced listening experience, from clear highs to powerful bass. The bass reinforcement algorithm enhances bass performance, delivering powerful, deep bass for a fuller, more vibrant bass. Enjoy the dynamic bass lines and rhythmic resonance. The comfortable vibrations and deep bass enhance your listening experience. Reduced Sound Leakage: The special earbuds' ear outlet design, which completely covers the entire ear canal, and our proprietary sound-cancelling technology minimize sound leakage. Whether you're in a quiet library or a bustling cafe, you can immerse yourself in your own world without worrying about attracting attention. Take your music experience to the next level 📲【Multipoint Capability, Direct Sound Transmission Technology, Bluetooth 5.3】 Using the app, TRUEFREE O1 can connect to up to two devices simultaneously, eliminating the need to manually switch connections. If you're playing music on device A, it will automatically connect to device A, and device B will automatically pause. Furthermore, when you receive a call from device A or B, simply answer the call. Direct Sound Transmission technology delivers sound directly to the ear canal, effectively reducing sound leakage. Direct Sound Transmission effectively prevents sound leakage issues like those found in other open-back earphones. Enjoy music while protecting your privacy. Featuring the latest Bluetooth 5.3 technology, it consumes less power, improves stability, reduces audio latency, and improves data speeds compared to Bluetooth 5.1/5.2 earphones on the market. Bluetooth 5.3 enables faster and more efficient data transmission, eliminating the worry of audio-video synchronization issues. 🔋【Charging Earphone Case, Comfortable Touch, Game Mode】TRUEFREE O1 comes with a rechargeable earphone case that automatically charges earphones when placed in the case. A single charged earphone provides up to 10 hours of continuous playback. By placing the earphones back in the charging case, you can extend playback to a total of 45 hours. The charging case is made of high-quality PC/ABS material, combining a smooth feel with durability. Its comfortable grip and excellent durability ensure comfort even during everyday use. It also features a Game Mode that minimizes audio lag and improves audio-to-screen synchronization. Game Mode enhances the immersive gaming experience. For example, audio-to-screen synchronization improves gameplay accuracy in action games and racing games that require fast, real-time reactions. It's the ideal companion for gamers seeking the ultimate gaming experience. 😊 [Touch Sensor, Waterproof, 12-Month Warranty] TRUEFREE O1 is equipped with a touch sensor, allowing you to easily control music playback, pause, skip forward and backward, answer and reject calls, and use Siri (voice guidance) with ease compared to other earphones. Furthermore, they are IPX4 waterproof, protecting them from splashes of water from all directions, so you can use them with confidence even in sudden rain or when sweaty during intense exercise. Our products come with a one-year warranty, and we will respond promptly in the unlikely event of a defect. (Note: Please use a compliant power adapter (5V/1A) for charging. Otherwise, the voltage may be too high or too low, preventing the earphones from charging.)
