To pair the device, all you have to do is turn on the power button (the light will flash and it will also make a noise) then you turn bluetooth on your phone and select the device. The speaker will then make a sound to let you know it paired. You can turn the volume up or down on the device (and on your phone, so I usually set my phone speaker at medium volume and then just control the rest on the speaker).
I cleaned my house and had Pandora playing through this and it was great! The music sounded great and I could just take it with me wherever I went. I also have set it on my counter in my bathroom and listened to music while showering. (I set my phone outside the door, so it didn't get affected by the steam).
What is unique about this is that it also comes with a port and connecting cable so you can listen to music on non-bluetooth devices (like mp3 players). This allows you to enjoy the loudness of the speakers with anyones phone or music-playing devices!
This speaker is big and the sound quality is excellent. I am very happy with this product!
