A:AnswerVery Easy - plug device into charging dock, then plug charging dock into USB on computer (may be able to plug device directly into your computer with USB cable). From here there are multiple ways to add music to the device. You can do it through a media program such as windows media player, or you can open your file explorer and drag and drop files onto it. They typically work just like a flash drive.
A:AnswerYes, they will and they are. It comes with four (4) different diameter ear-buds: small, medium, large and large-long for the smallest ear canals to the largest. The head band is bendable and would be adjustable to a smaller head. It also has an “rubber band” attachment that helps keep it snug on the head.
A:AnswerIts required to change earbuds for waterproof; it comes with the two types/sets of earbuds; I just left the waterproof earbuds. Earbuds are really good fit, they do not fall.
A:AnswerThe battery is not accessible to replace. If you buy it from BB, you should be able to take it there. If they offer an extended warranty and you are concerned about longevity I would purchase it. They are well built, very solid construction. I am pleased with mine. Hope this helps
