These headphones clip securely and comfortably over your ears, delivering a snug fit for great sound on the move. Open-air design lets ambient sounds through, so you can exercise safely. 
All three weights plus the Open Type frtauees (contextual alternates, swash, etc) work for me; I downloaded it when I posted this last month. If something isn't working, you can contact the Lost Type Co-op and I bet they can help you.
