Review on Portable acoustics Sony SRS-XB13, beige by Micha Gabriel Czajko ᠌

The fact that it has a built-in microphone and can be used hands-free is also useful, however I suggest lowering the level. Its benefits Lightweight and small, shielded from moisture and the elements. Most importantly, it is challenging to conceive a bass with more power given its size and weight. Several drawbacks There is an oddity: the speaker cone is the sole place where the whole sound spectrum is transmitted, and when it is turned to the side, some frequencies are audibly worse. Furthermore, 16 hours of continuous running at maximum power is not recorded.
