Do not ever want or you can use to listen to music an earphone. Whether on the road, in the garden or in the office: So a Bluetooth speaker is a practical matter. A fortiori, if so a speakerphone for Smartphone's connected. As in the present here Sony SRS-X2 NFC.

The basses could have a bit more bums, the highs sound somewhat nervous and strained. But, as I said: Those who expect more, just needs to invest a few euros more and then carry around.
