I purchased this a few years ago. I'm selling it because I no longer use it. I haven't been able to confirm its functionality as I don't have a charger, but it was working normally until I stopped using it. The charging ports are Lightning on the left and Type-C on the right. Below are the details from when I purchased it ↓↓ ■Functions and Operation■ ・Automatically enters pairing mode when the case is opened (no pairing needed after the first time) ・Pairing method Requires long charging for the first use. Please use the included Lightning charging cable and charge for about 5 hours. With the case fully charged, open the case lid and connect from your smartphone's Bluetooth settings screen. After connecting, it will automatically connect the next time you open the case. ・Intuitive touch operation: Play/Pause: Tap once Skip back: Tap the left earphone twice Skip forward: Tap the right earphone twice Volume down: Tap the left earphone three times Volume up: Tap the right earphone three times Activate voice assistant (Siri): Long press (about 1 second) ・Rich and three-dimensional sound design that sets it apart from low-priced models ・Overwhelming immersion created by clear high frequencies and deep, resonant bass ・A highly-rated model around the world, including the United States ・A sophisticated device with an excellent balance of design, functionality, and sound quality 【Set Contents】 ・Bluetooth earphones (left and right pair) x 1 ・Charging case 【Product Specifications】 ・Equipped with ENC noise cancellation ・Continuous music playback: Approximately 3.5-4 hours ・Built-in microphone for calls ・Automatic power ON/OFF function ・Compact yet high-capacity charging case ・Design that pursues a comfortable fit ・Compatible with both iOS / Android 【Important Notes】 Product images and specifications may be subject to slight changes without notice. ・For environmental reasons, it will be shipped in simple packaging (without a box).
