I ordered this as a joke for my friend, but it turned out to be very good and I ordered another one for myself, the material is synthetic but it has been good to go for runs as the weather turns colder, the built-in headphones were a perfect added bonus. I'm nervous about washing it, but it does say it can be washed. Arrived without any charge but was fully charged in under 2 hours and easily paired with my iPhone, and dropped 10% in an hour (very good battery life!). The speakers are more speakers than headphones, so if you're walking down the street, others are likely to hear what you're listening to. All in all, I would recommend
