I purchased this item mainly for the bluetooth facility. The bluetooth setting up (pairing) with a mobile or tablet is extremely straight forward. At this price, I wasn't really expecting it to be very good. The seal on the box indicates that these were originally intended for sale by Marks & Spencer's. The device itself comes with a feature that allows it to be extended by unscrewing the middle section and replacing it with a wider wider middle section (supplied).. This obviously moves the speakers further apart (by about 10 inches), so creates a "wider" sound. Besides the bluetooth, it has one 3.5mm headphone style socket as input and comes with 2 cables. One of these goes to another 3.5mm plug (allowing you to connect it to the headphone socket of an MP3 player (or whatever). The other cable converts this input to 2 phono plugs, which allows you to connect it to just about any other type of audio output (TV, DVD, piece of Hi-Fi, etc). The device comes with a remote control allowing you to switch between the bluetooth and the other input, as well as controlling the volume, added base and the 3D effect. It also comes with screws etc for wall-mounting the unit (if you don't wish to have it standing on a table or something similar). All in all, a surprisingly smart piece of kit and at this price a bit of a bargain.
