and they are comfortable when in
The sound is ok, and they are comfortable when in.  They are a little difficult to get out of the ear, but it is manageable.  The reason why I gave 4 stars, is because for about the same price, I have bought some other plugs that sound a little better.  These have a nice case, though.  I would wear them when sleeping, because they fit so deeply into the ear.  Very discrete
Rating: 4 stars
