Very good sound (though a bit stained, so if the studio monitors is more your preference then perhaps these are not for you) out of a small package. Is the battery to buy for better mobility.
+ Good sound
+ Small size
+ Can be used as both Bluetooth speaker (for example, smartphone) and desktop speakers
- Perhaps slightly expensive (depends on what you compare it with)
- Not included battery pack (would have been good for those who love to switch between cable and Bluetooth, and move them around as needed, or use them where power outlets are not available)
- Some cards included cable between the L and R
- Not included line-in cable
