The soft foam pads on the headphones are comfortable to wear for long periods of listening. I read the other specs and fearures, but because I mostly use my phone to call, text or send messages and use the browsers and other basic fearures, I didnt pay much attention to the other features. The soles are skid-resistant. There are multiple options and creative ways of completing the objectives in hilarious fashions, using a miriad of objects. Mounted into a 2x4 they sag quite a bit and now have a slight bend when the bikes are off. STOP! I have to return this shoes, as much as I love zumba in general. I also have the LG Tones (Platinum & Infinum). fast usb-c charger, and avoid that electrical nightmare. I wish someone had written this before I got this product.
