When connecting for the first time, open the charging case of the earphones (you can also take out the earphone units), search for "M52-ENC" in your smartphone's Bluetooth settings and click to connect. No need to take the Bluetooth earphones out. After connecting manually for the first time, when you start again, it will automatically power on when you open the lid, and connect automatically in just one step. It provides a more comfortable user experience than other earphone models with the same specifications. 2. 【Up to 60 Hours of Playback & Clear LED Display】 With a 500mAh large-capacity battery and an energy-saving design, the earphones alone can play for 5-6 hours on a full charge, and up to 55 hours with the charging case (usage time varies depending on volume, content being played, and usage environment). Also, a clear LED display is designed, allowing you to check the charging status of the left and right earphones, and the remaining charge of the charging case is clearly displayed in numbers from 1% to 100%. 3. 【High-Quality Sound Equivalent to ENC Noise Cancellation & Comfortable Fit】 These wireless earphones maintain the same compact size as before while achieving significant functional additions and improved sound quality. You can hear the details of musical instruments, so you can enjoy the mid-high and low frequencies dynamically. Especially at 50% volume, you can feel the depth and impact of the bass. This provides a high-quality call experience. Perfect for online courses and meetings! Enjoy clear calls like you've never experienced before. 4. 【Touch Sensor, Easy Operation, and Excellent Fit】 With a single touch, you can easily operate the earphones to play/pause music, skip forward/backward tracks, answer/reject calls, and activate SIRI (voice guidance).
