I am very disappointed with these ugg slippers. I still think they look badass (for headphones), but just not meant to be. Other types would not be so forgiving. I bought the Turtle Beach earbuds but those were so uncomfortable after a while (my ears hurt so bad). Were taking a full inch between my heel and the slipper and they fall off my feet when walking. Thats great! Two aluminum adult bikes should not break a hitch bike rack. Sturdy and well made! Not sure it’s worth the money you save if you care at all about battery life. My only complaint is that sometimes the top cap slides back and is just dangling.
