Pros
Pro Great for working out/running
Not only do these have an IPX5 rating for splash/sweat resistance, but there also is a nano-coating applied to the interior parts. The chances of liquids causing damage to these are substantially minimized.
Pro Filters out noise frequencies
These have active noise cancelling which helps minimize outside noise frequencies that may mix with your music
Pro Very snug fit
The Anker NB10 earbuds have plastic hooks that go behind the ear. These help maintain a snug fit and prevent the earbuds from accidentally falling out of the ears.
Pro There are playback controls on the earbuds
The playback controls are placed on the earbuds, making it easy to switch tracks and change the volume without having to take out your phone or portable music player.
Cons
Con Below average sound
Bass is not very powerful, mids are recessed and highs can get harsh. These work okay for casual listening, though if you want detailed sounding or powerful audio then these may not perform well.
