Love this speaker the sound quality is really good and clear even when turned up to its fullest it's not muffled it's still clear and the base on it sounds good to. I was surprised by how good the sound is for a small speaker. The size is great it's small so great if you want to take away anywhere with you. Very simple to work and easy to connect simple as turning on the speaker and putting the blue tooth on what every device you want to use it on the blue tooth speaker will show up connect and it's simple as that fantastic speaker love the light on the top of the speaker easy to see in the dark. This also comes with a plug in wire to connect your speaker and a chagering wire for your speaker. Charge lasts very well had it on for 5 hrs yesterday and still charge in it so must last awhile it's not ran out since I've had it played time upto now about 5 hrs also comes with a bag to keep your speaker & wires in.
