Hey, ExpertReviewer here, reviewing the Sony Ericsson portable speaker.
At less than £20 its quite hard to fault a portable speaker, especially this one. Whilst remaining a tad under £20 this little speaker can deliver acceptable sound quality for an exceptional price. The overall sound quality of this speaker is fairly respectable, considering its compact design and cheap price. It tends to provide a sound quality that is easily listenable to, although it does not output a particularly loud audio, so don't be expecting to have this blasting away on the bottom floor whilst listening to it on the top floor, as it simply isn't capable of this. Also another slight downside to this is that it tends to struggle with songs that have a high base, as it sometimes rattles and fuzzes whilst the volume is maxed out.
Overall the device is a reasonable buy if you are looking for a cheap, portable speaker, just don't expect to go DJ at a party with this!
