I bought two, and have them both plugged into a two-port charger, and I have them connected together to make a single speaker. The sound is really good, and I could unplug them and pack them around the house if I wanted. They're also loud enough I can hear them through the whole house if I wanted, but soft enough to use for sleeping music. Pairing them isn't that hard, you just have to follow the instructions. I had them cease to pair correctly once, but I turned them off and back on, and they connected back together easily.
