A:Answer Yes there is a left and a right ear. They are labeled and need to be put in the correct spot for charging too. They work together or separately if you want to use just one. In the app you can choose which one you want as the master and what prompt which bud can do with which command- 1 tap/2 tap/hold.
Also if you take one out the other will still work. When you take both out the auto stop playing it is a nice feature. I have 1 tap pause so I can listen around me if need to, 2 taps skip songs( left back ,right next) and hold volume control( left down, right up) but you can change to whatever you preference is in the app. I use mine mainly for music while running or working out, have not used to make calls. Had them a couple weeks now and have not had to charge them since the first charge using them 3 hours at least a day. I really like them.
