First very pleasant surprise, originality of packaging and form of the speaker: a donut in the box exactly as in "Fast Food". The donut is quite small and light, easy to carry.
First step: we must charge the device and it asked me for an hour. When the red light goes out, is that the device is ready for operation.
To sail to the Donut android just pass by Bluetooth.
For a smartphone (not android), NFC plate is used (to be placed on the smartphone).
This unit can play music, but not only, you can also take our phone calls. Theoretically, the range is 10 meters, but in my case I put the donut on the coffee table, I'm out of the house and quickly the connection was cut (thickness of the walls?). By cons uphill upstairs the device still works, but it took a few seconds to allow time to adapt to the Donut.
The sound quality is decent.
After fifteen minutes, if one does not put more music device goes to sleep.
I'm happy with this speaker that is very powerful for the price. Not having to worry about making CDs, find a stereo available is still a major asset. It is quite suitable for listening to music in small groups, during an evening with family or friends.
This is a powerful speaker very original in form, easy to install, easy to use, on which it is lovely to listen to music and receive phone calls.
