"Excellent Features"3.5 starson by MarkDK2
Pros: Love that on the iPhone 4 now I hear everything including who is calling though this headset. The battery meter that pops up on the iPhone to tell me how the Icon is holding out is cool too.
Cons: I have yet figured out which is the best fit and getting the headset to work properly 100% of the time where people at the other can hear me well has not happened yet, but I will get it I have only had this for 2 days.
Summary: Overall I got mine on an auction site and did not pay much. The piece works well and is seriously innovative.
