With 33 watts, this thing packs a punch. It was super easy to setup, and comes with clear instructions. Basically, plug in the green 3.5mm jack into an output source (mp3 headphone jack, tv headphone jact etc) and plug in two cables behind the subwoofer, then plug in the smaller speakers in the subwoofer. Please note: - comes with a Euro plug (two sticks instead of 3) so you might need to order an adaptor to go with this. Firstly, wow, these speakers are brilliant, does exactly what the description says. The bass control is amazing, you can set it to full and you wont get a distorting sound, but a clean massive deep bass that sounds perfect and accompanies any sound coming from the smaller speakers, which give it a good balance of treble and bass. Their perfect for quiet listening and, just turn them down and you still get a crystal clear sound and no distortion. These speakers are also very well built. The front is plastic and gives it a shine. The blue led is a nice design touch to. All in all, brilliant speakers. There are now newer versions of this speaker, so check SoundLinks website and compare the model. I believe the new versions incorporate power saving features and slightly different designs.
