Wavemaster MOBI-2 Compact Speaker with Bluetooth White

Bought for my 10 year old daughter to listen to his MP3 sansa zip.
Her little sister 8 years old already have the MOBI-1 (bluetooth so) in glossy black. The sound is the same between the two versions. IN the end, these small speakers savèrent enough practice and limit the use of helmets which is probably best for the health of children eardrums.
The pros:
- Mobile and shared listening to music from a player / smarphone
- Bluetooth (will be useful later when she has a drive that broadcasts in BT or for parents if you want to borrow it!)
- Design and matt white appearance
- Charging via micro USB
- The quality of its sufficient for children
- The bonus cover
The -:
- Limited in power and low for audiophile ...
- Mono
- No automatic standby
