If not it's Bose. Really not disappointed! I was looking for non intra because I do not like the stethoscope headphones effect when walking and I'd also hear noises around when I walk in the street. These headphones have scared me at first because of their attachment system in the ear but in the end it's a real treat! You do not feel them, the sound is excellent, not against, as provided sound insulation is very small. They stick absolutely to my use, I just regret not to be taking the model with the microphone because I love these headphones so that I would spend my calls.
