I liked various funny features like "quick focusing" or something like that, when you put your hand to your ear and the environment becomes audible. It is also convenient when the headphones are connected to a PC and a smartphone at the same time. That is, you listen to music on your computer, a call comes to the smart, the music pauses, you talk and the playback continues. There are different modes for different environments, which are automatically switched. Touch control is quite convenient.
