The FreeBuds SE4 ANC earbuds are designed to deliver an immersive and intelligent audio experience with long-lasting comfort and performance. Each earbud is powered by a 41 mAh lithium-ion polymer battery, while the charging case houses a 510 mAh battery, providing multiple recharges for extended use. The earbuds support wired charging via USB Type-C, with an approximate charging duration of 110 minutes for the case alone or when charging both the earbuds and case together. The earbuds themselves can be fully charged in about 60 minutes when placed in the charging case.
When it comes to battery life, the FreeBuds SE4 ANC are built for endurance. Users can enjoy up to 7 hours of continuous music playback with noise cancellation enabled, extending to an impressive 35 hours when used with the charging case. With noise cancellation disabled, playback time increases to 10 hours per charge, or 50 hours in total with the case. For voice calls, the earbuds offer up to 5 hours of talk time with ANC on and 25 hours including the case, while disabling ANC extends call time to 6 hours per charge and 30 hours overall.
The earbuds feature intuitive touch controls for effortless operation. A double-tap allows users to play or pause audio and answer or end calls, while a triple-tap can skip tracks by default. The touch-and-hold gesture provides versatile control options, such as switching between noise cancellation modes, adjusting the volume, activating the voice assistant, or rejecting incoming calls. A three-color LED indicator keeps users informed about the connection and charging status.
Equipped with Bluetooth 5.4 for stable and efficient connectivity, the earbuds support low-latency gaming and proximity pairing prompts for quick, hassle-free setup. They incorporate Hall effect and touch sensors for precise detection and smooth user interaction. Each earbud houses a 10 mm dynamic driver that produces rich, detailed sound across a 20 Hz to 20 kHz frequency range. Enhanced with call noise cancellation and Multi-EQ audio tuning, the FreeBuds SE4 ANC deliver clear calls and customizable sound profiles to suit different listening preferences.
Supporting popular audio formats including SBC, AAC, and mSBC, these earbuds ensure compatibility with a wide range of devices. Compact and lightweight, each earbud measures 32.3 × 21.3 × 24.0 mm and weighs just 4.3 g, while the sleek charging case measures 46.5 × 61.8 × 24.7 mm and weighs 36 g, making it easy to carry wherever you go. With their blend of advanced features, powerful sound, and long battery life, the FreeBuds SE4 ANC are the perfect companion for music, calls, and everyday use.
