The ear pieces are comfortable for a while then they really start to hurt. originally purchased for Alaska Inland Passage cruise (which has again been rescheduled) but sure was great to have on hand during the Arctic Storm. AND this adapter started charging a USB battery pack (Anker 10,400 mAh). It was like a watered down high school version of Red, White, and Royal Blue. Its saved floor space compared to longer rack that i have. UPDATE: Replacement received and the conclusion is the child 10 and toddler 10 are the same shoe. These are a GREAT value and Ive used them a lot since their arrival. M1,2,3,4 are really good, no play or issues. I have an iPhone 12 Pro Max and it fits! They dried sitting out in our condo & were completely ready the next morning, even though my husbands & sons Body Glove shoes were not.
