The facility, ie the connection with cell phone or Gigaset phone's done in 1 minute, the coupling may be multiple. The sound is fine, even if the function as headphones for mobile music. Here, the supplied cable is already settled with 2 earpiece for the stereo. The part is placed around the ear with the headband. The part also sits on only on the ear and not in the ear in there. This is very pleasant during extended wear. Headphones is actually so easy that one ever forgets him lay back. Definitely a buy recommendation on my part.
