This is my second set and I can even use one from one set and one from the other. If there is trafic around the noise cancelling is like inexistent, but the microphone or the connection is better than V8, V9 and V15, Mpower and even a Blitzwoolf. 8 say this as I have several friends that wore complaining about the way they heard me on the others ( they are using Jabra, Samsung, Plantronics £149).
arrived fast. earphones as described
