ANC update has spoiled the complete experience. Battery life has reduced to half even if You never use ANC option. Not impressed with the update. Wonder how many people would have asked for ANC when we didn't expected the feature at all at the time of buying the earphones 3rd class, pathetic customer service. No service centre list being provided by this company. Also after registering service request for product under warranty, no call is received for resolution of the issue. Don't Buy Jabra
