The headphones are wireless, they do not have any protruding features, and the battery life is fairly satisfactory (I used it to listen to music for several hours before putting it in its case so that it would not interfere with other things). Below are some downsides: A non-obvious manner to install in the ear, along with a touch "wall" that is naturally pressed during installation (so you have to first put them in your ear, and then switch on bluetooth on your phone).
