New Upgrade I7S Earphones we chose 4.2 bluetooth and they are different with other manufaturer who they guys sell the earphones need to press a white connects with another earphone once you need to make it connecting .Ours only need to turn on both switches at the same time , once you see one with flash blue in red and other one is slowly in blue . It means that they two connect successfully and now only connect your bluetooth devices search to "TWS-I7" , then both earphones they work properly .
