I like the idea of the Skullyboom, but there are some flaws in the execution that render it only 3 stars. First, the ports on the back are packed in so tight against the clip that their rubber covers do not have enough room when the cord is plugged in. At first it wasn't a problem other than the annoyance of trying to get it plugged in, but after a short while of use, the connection has gone bad, so unless I hold it in place, then it isn't connected properly. Also, the clip is so super tight that it is hard to clip on and then it is very hard to get off. I wish there were multiple ways to attache the product. Finally, as others have written, the sound quality isn't great. It is better than using the speaker on my iphone, but just don't have high expectations.
