😃Just want to say that you can rest assured that all our products are of high quality, and if, due to manual mistakes, any faulty products get mixed in the delivery, there are always refund policy and replacement policy.
As for the difference, mainly about the battery life and battery capacity (one is 20H with 200mAh for the case and 50mAh for the earcuffs, and the other is 24H with 350mAh and 60mAh)and more differences in design and style, you know, in the charging case, not to mention there are also Doraemon-theme patterns(if that is what you are referring to).
