I am totally satisfied with the Sennheiser headphones. Sometimes having trouble understanding some dialogues of films I wondered incessantly to my husband (who had quite a bit !!) to repeat myself. Since I use this headset I understand everything (yes!) And I can set the volume level that suits me without boring my surroundings. I find the quality of the sound particularly good and I find the atmosphere of a movie theater ... I recommend this helmet for light deaf (like me) or greater and even to those who hear perfectly well.
