Many times my interlocutors complain that they don't hear me well. It is possible that I came across a faulty one, but mine don't fit well in the case, resulting in occasional failure to charge and unpleasant surprises when I try to reuse them. I have no experience with other headphones of this type and I don't know how feasible it is, but it seems a little strange that you can't use each one independently. I mean, for example, at the office where I only wear the right one, when it runs out of battery, I have to wait for it to recharge while I could easily use the left one that is charged. Overall, I was not satisfied, but their price is reasonable and their application is very good and comfortable for a long period of use.
