Full Wireless OWS Earphones F3 - Black 【Doesn't Block Ears & 4.5g Ultra-Lightweight & Secure Fit】 Unlike the closed-in feeling of canal-type earphones, the vibration and pressure of bone conduction earphones, and the neckband of bone conduction-like earphones, Mongeese Bluetooth earphones don't block the ears, reducing the burden on the eardrums, preventing sweat buildup, and keeping the ear canals from getting stuffy. 【Industry-Leading Bluetooth 5.3 + EDR & Hi-Fi High-Quality Sound & Instant Pairing】 These air conduction earphones use industry-leading Bluetooth 5.3 + EDR, dramatically improving communication speed, distance, and stability. At the same time, power consumption is lower, data transfer is faster, and interference resistance is stronger. Thanks to innovative Bluetooth pairing technology, after pairing with your smartphone for the first time, you can automatically connect instantly by simply opening the charging case lid when you use them again. It's also appealing that the earphones automatically turn off and start charging when stored in the case. 【ENC Noise Canceling & Clear Hands-Free Calls】 These Bluetooth earphones have a built-in directional high-sensitivity microphone that supports hands-free calls and are equipped with noise-canceling technology. They focus on picking up the necessary voice and blocking out surrounding sounds, allowing you to hear voices clearly during calls. 【25 Hours of Continuous Playback & Smooth Operation & Quality Guarantee】 The industry's newly developed overwhelming low-power consumption technology is adopted, and the Bluetooth earphones themselves can play music continuously for about 5-7 hours on a full charge. You can enjoy music playback for up to about 25 hours when combined with the charging case. (※ Playback time varies depending on volume, content, and usage environment). With touch controls, you can easily operate music playback/pause, call answering/rejection, volume adjustment, and SIRI activation/deactivation with a light tap of your finger. The accuracy and sensitivity of the touch controls have also been significantly improved, allowing for stress-free touch control.
