I took it for noise reduction. completely satisfied with this feature in the plane, almost complete silence even without music. I only hear a human voice. at the expense of using it as a headset is a bad idea, the interlocutor does not hear me well. touch control is also so-so solution would be cooler if there were regular buttons I won't say anything about the sound. On a normal source, the difference between wire and bluetooth is noticeable. but not everyone uses a good DAC or sound card. for a long time do not vilify his head and ears get tired after 2-3 hours. woke up to take them off
