I had to write in and contradict the review saying you can only use this on your right ear. the instructions show you how to switch it, and you can even switch the volume control from the bottom to the top, so it is on the top regardless of which ear you use it on. NOTE: if you want a Y splitter for car or home charging for this, you have to use model P000, not the one that comes up on a search, because you need a splitter with 2 mini-USBs (one for your phone, one for the headset). Only had it one day, so can't comment on the other issues.
