Sealed (with silicon eartips) and un-sealed (half-in-ear) are the most popular form of wireless earbuds, but another type is coming in, open earbuds that let your ear canal exposed so you can comfortably listen to the outside world while enjoy your tracks. These earbuds are equipped with dynamic driver or deliver sound by vibrations directly to the cochlea, in this post we only focus on the open wireless earbuds with dynamic driver (that push air to deliver sound to your ears). Because of open design these earbuds do lack some bass, but for calls and running outdoors they are great.
