The connection between the headphones and the phone / laptop works by pushing a button, even so far without connection problems. The transmission distance is not so great ... maybe to the 10 meters, but no wall may be similar between his ... Even so, the headphones are not suitable for jogging, etc. since the speakerphone is too hard and the supplied in-ear bracket not stuck - by slipping the headphones or fall out. Only partly recommendable therefore.
