The JBL open-ear earbuds don't fully cover your ears, because they don't go into your ear canal. That way, you can still hear ambient noise and know what's happening around you. That's useful when you bike through traffic, for example. Because there's nothing in your ear canal, the earbuds feel comfortable. That way, you can easily wear them the entire day. These JBL open-ear earbuds are splash proof, so they can withstand sweat and a light rain shower.
