This mic is definitely sensitive. Its a great little charger. First off I love them couldn?t of asked for a better pair of sunglasses for those who said they are loose and fall off face there?s adjustments on the screws to make it fit correctly Hope this helps others NO support or replacement parts were available. The case is beautiful, however; I had to force the charging case in, only to realize, the top of the bling case will not close and now the charging case will not open completely for me to get the pods out. Nothing is rattling on my desk. This doesn?t have any odors, and cleans very well. Point is, NEVER order from them directly because it took me over 2 months to get my money back for this piece of garbage headset. Dont be afraid to first adjust to the size cause its expected that youll shrink if you follow a healthy diet and exercise. Left/right markings are almost impossible to see, but they are there.
