I have had my earphones for about 15 years and because of the condition of the cushions, I was going to throw them away. Besides the comfort, they are the only slipper that comes in my preferred size. The replaced case has more scrapping than the previous one. So I got her the camera. Now I have great sound and a beautiful head unit. Zur Kapazität des Akkus habe ich keine Angaben gefunden. Cannot really tell any difference from the originals. These shoes are perfect for me! 10-star product and gift idea! This is mostly to get the towels to fully dry in the winter.
