Indeed, AKG N400NC offers wireless charging. Wireless charging is convenient, and you don't have to charge the earphones with a wire anymore. With just 10 minutes of wireless charging, you can listen to music for 6 hours. And when it is fully charged, it lasts for up to 5 hours when the ANC is turned ON. So if you're looking for earbuds that will charge fast wirelessly, then I would recommend AKG N400NC.
