Plaud's new earbuds come with a charging case that has its own mobile connection. The Plaud One Limited Explorer Edition costs US$249.99 in the United States, and only 2,000 are being made worldwide. Plaud lists the case with 4G LTE and an eSIM. TechCrunch, Engadget, Android Authority and SiliconANGLE all reported the announcement on Thursday, 27 August. This story's based on Plaud's spec table, still online on Sunday, 30 August, and the same site had a banner saying a 30 percent offer on the Plaud NotePin ended that day.
