The Dóttir Freedom are IP68-rated to withstand dust, dirt and sand as well as underwater submersion. They can therefore be worn in difficult environmental conditions as well as when swimming. The wireless earbuds have an internal memory for audio content, so users do not need to have their smartphone with them to listen to music on the go. The earbuds sit in a small, round charging case with a diamond pattern adorning its metallic surface. They are solidly made and offer a secure fit during physical activities.
