4.5 Amazing Speakers wezter | 18/08/2013 | See all wezter's reviews (1) I bought one of these speakers to boost the sound coming off my portable DVD player and I was not disappointed. I was so impressed with this speaker that I bought a second one and they easily attach to one and other, and I can now arrange them either side of me giving a great stereo sound. In fact you can buy as many of these as you like and just keep adding them on to each other. I got about 14 hours playback on one charge of this speaker. These speakers have a very rich sound.
