【Long Battery Life】 With a 1.5-hour full charge, you can enjoy approximately 10-12 hours of talk time or continuous music playback. Furthermore, to prevent loss of the earbuds, a 500mAh charging case is included, allowing you to fully charge the earbuds about 5-7 times. 【Dedicated Hands-Free Calling Microphone & Mute Function】 The Bluetooth headset is equipped with a unidirectional microphone and CVC8.0 noise-canceling technology, which accurately picks up your voice and blocks out surrounding noise, enabling clearer calls. You can deliver clear audio to the other party even in noisy environments. Also, to protect personal privacy, a mute function is included. During a call, pressing the "MFB key" will prevent the other party from hearing your voice, which is convenient during meetings or when handling confidential information. 【Ergonomic Design & Compatible with Both Ears】 The Bluetooth earbuds feature an ergonomic, ultra-lightweight 12g design for comfortable wear and reduced ear fatigue. The in-ear design, combined with a three-point support system, makes them less likely to fall out of your ears compared to other types, allowing you to easily make calls even in crowded vehicles. 【Stable Bluetooth 5.4 Connection, Auto-Pairing, & CVC 8.0】 Upgraded to Bluetooth 5.3 technology, significantly improving "sound skipping" and "sound cutting." The transmission distance reaches up to 10 meters (without obstacles). After the first use, the device automatically remembers and connects automatically when turned on again, eliminating the need for complex manual pairing. S1009. 0.3999.800 $0.215.500
