Experience the freedom of open-ear audio with the Soundcore C50i Open Ear Earbuds, the innovative clip-on headphones engineered for runners, fitness enthusiasts, and active users who demand powerful sound, secure fit, and situational awareness without compromise. At its core lies Soundcore’s advanced FlexiClip Design, featuring a flexible, ergonomic clip that gently wraps around your ear for a secure, pressure-free fit that stays in place during intense workouts, long runs, or daily commutes—verified by third-party testing to maintain stability through 10,000+ movement cycles without discomfort or slippage.
The custom-tuned 12mm dynamic drivers deliver powerful, punchy bass and crisp, detailed highs that bring your playlists, podcasts, and workout tracks to life with exceptional clarity. Unlike standard open-ear designs that sacrifice audio quality for comfort, the C50i’s acoustic engineering ensures rich, immersive sound that rivals traditional in-ear earbuds while maintaining the safety benefits of open-ear listening—allowing you to hear traffic, conversations, and environmental cues during outdoor activities. Certified for Hi-Res Audio Wireless with LDAC codec support, these earbuds preserve studio-quality detail from streaming services at up to 990kbps wireless transmission for lossless audio experiences.
For all-day listening, the integrated rechargeable battery delivers up to 28 hours of total playtime (7 hours per charge + 21 hours from the charging case)—sufficient for full workweeks, marathon training sessions, or extended travel without mid-week recharging. For urgent situations, the USB-C fast charging provides 2 hours of playback with just 10 minutes of charging—ideal for last-minute workouts or backup power during busy schedules. The intelligent battery indicator displays real-time power status via LED alerts, eliminating unexpected shutdowns during critical listening moments.
The IP55 water and dust resistance (IEC 60529 certified) guarantees protection against sweat, rain, and dusty environments—making the C50i ideal for intense gym sessions, outdoor running in unpredictable weather, or cycling adventures without worry. Unlike earbuds with basic splash resistance, this robust certification ensures reliable performance even after heavy sweating or light rain exposure, providing peace of mind for active lifestyles and demanding training conditions. The sweat-resistant nano-coating on internal components adds an extra layer of protection against moisture damage over time.
Powering seamless connectivity is the latest Bluetooth 6.0 technology, delivering faster pairing, more stable connections, lower latency, and improved power efficiency compared to previous Bluetooth versions. The multipoint connection feature enables seamless switching between two paired devices simultaneously—perfect for athletes managing smartphone calls and smartwatch notifications, or music lovers transitioning between tablet playlists and phone alerts without manual reconnection. The low-latency gaming mode (<60ms) ensures perfect audio-video sync for mobile gaming and streaming content.
Measuring compact dimensions per earpiece and weighing only 6.2g each, the C50i achieves featherlight comfort for marathon listening sessions. The ergonomic FlexiClip design distributes pressure evenly around your ear without inserting into the ear canal—eliminating the discomfort, ear fatigue, and hygiene concerns associated with traditional in-ear earbuds. The three-size ear wing tips (S/M/L) provide additional stability customization for different ear shapes, ensuring a personalized, secure fit for any user.
For clear communication, the dual-microphone array with AI noise reduction isolates your voice during calls, verified to achieve 93% speech clarity even in moderately noisy environments like gyms, busy streets, or outdoor trails. The touch controls on each earpiece enable intuitive management of playback, volume, calls, and voice assistant activation with simple gestures—no need to reach for your phone during runs or workouts. The auto-pause feature stops playback when you remove an earbud, conserving battery and preventing missed audio cues.
Certified for active lifestyle use with comprehensive audio performance, these earbuds support Soundcore app customization (iOS & Android compatible) with EQ presets, firmware updates, and find-my-earbuds functionality—ensuring your earbuds evolve with your listening preferences over time. The transparency mode naturally amplifies ambient sounds for enhanced situational awareness during outdoor activities, while the wear detection automatically pauses playback when earbuds are removed.
Whether you’re training for a marathon, cycling through city streets, working out at the gym, or simply enjoying music while staying aware of your surroundings, the Soundcore C50i delivers powerful audio with secure, comfortable fit. Its open-ear FlexiClip design (vs. in-ear earbuds) provides all-day comfort without ear canal pressure, while the 28-hour battery life proves that quality wireless audio shouldn’t require constant recharging—making every workout more enjoyable, connected, and perfectly soundtracked.
