I have them for quite some time at least 4 going on 5 yrs. They are good and the battery life is very good and you don’t have to constantly charge them. I brought 2 pairs green and black. To charge it you need the same one iPhone used before the C type. The stay charge for weeks, literally! If not months. The only down fall is the mic is not that great and it can drop your calls not all the time. You sound muffled and not loud enough for others to hear. Lastly, when they are disconnected if your device is in the area of the earbuds it will connect without your permission. But over all it’s pretty good.
