Just browsing the Sony Centres Direct website and noticed this REFURBISHED portable Bluetooth speaker reduced from £349 to £149. I've bought several items from Sony Centres Direct in the past, and I might have been lucky, but I've never had any issues.
I have owned a smaller Sony SRS-X3 spearker for about 3 years. It's a nice little speaker and sounds far larger than it's size. This one is bigger and looks as if will go quite a bit louder.
Not sure how many of these items they have in stock (I haven't purchased this time), hope somebody will find this useful.
