I haven't tested these out for myself since they were a gift. But these were a gift for my father and he is on-call for work so no doubt he'll be out and about in sometimes noisy places while receiving a job. So far he says that they work well and are pretty comfortable to use except for the wings. Overall, seems decent.
Edit: The wings are really only a minor inconvenience: they are easily removed so it really is a non-issue. I gave this three stars before because I did not test these myself so I cannot properly review the product. Even now I won't be testing them since these weren't mine, but a gift for my father. Suffice to say though that it seems to be doing it's job: reducing noise and providing good voice call quality, according to my father. What I can definitely vouch for is TaoTronics' customer service. They reached out to me about correcting what is really a minor inconvenience and what most companies would just ignore. So they will definitely help those of you with valid concerns and problems.
