errands, church, lawn work, vacation, convention. Im so glad I bought these! They stay on! The straps are very comfortable and they are super cute! It is well made and attractive. I do not recommend these batteries. You can connect the cable into most devices with AUX ports, such as the MP3 players, phones, and computers, to name a few. I took before pics and while wearing it because words just can’t show how incredible this product is! Though they are comfy and have a nice colour. The aluminum base plate is remarkably thick/heavy duty.
