Summary: bought the product mainly to use whilst flying. Didn't have a massive expectation due to the price but I thought it would still be loads better than standard on flight issue. Apart from the light coming on there is no other difference when you turn on the noise cancellation. Waste of money, look elsewhere.
Summary: In fact, these do provide significant reduction below about 80 Hz, but that is only a small fraction of the frequency spectrum. I'm sure these would be nice on an airplane or other situation where most of the noise is very low, but in everyday life they are pretty useless. I initially thought these didn't work at all; I had to use them with my head 12" from a running air conditioner in order to actually hear a difference.
Summary: I had purchased these earbuds a short while back because I was looking for a way to listen to my music and cut out ambient noises/conversations. These earbuds seemed like a sure thing from all the online reviews but to my disappointment, my experience was much different. I will say one thing, for headphones on their own, they isolated quite a bit of noise but not everything, and the NC feature did not work.
Summary: I bought these because I used to have a cheap pair of noise cancelling headphones that were over the ear and when turned on, the difference was amazing. Totally isolated from the room. With these, the music gets slightly louder but nothing. Can year the tv just as loud in the background as before and my wife's voice is the same volume. The performance of the speaker is about as good as the headphones that came free with my phone.
Summary: I decided that I would purchase these earphones in order to reduce the noise when flying abroad. They have proved very disappointing. I have used them in a number of different situations and I can say that there is no occasion when I was able to discern any significant difference in noise level when wearing them and without them.
Summary: I've tried these headphones in an office and on the airplane. In the office I couldn't tell any difference, while on the airplane I could tell a difference but it wasn't good or what I was hoping for. Sadly the sound quality is poor but at this price I'm not surprised. They also can get uncomfortable to wear after a while on long haul flights. I would suggest looking elsewhere.
Summary: La cancelación de ruido no aisla ni un 10%, nada que ver con la frase de Sony que indica que puede llegar a atenuar hasta un 87%. Deduzco que es simplemente estrategia de marketing. Lo que aisla bien son los botones que se introducen en los oídos, pero es atenuación pasiva. La caja con la pila y el circuito es por tanto un estorbo, pues no sirve para la función para la que se hizo y en cambio tiene el problema de que su peso tira del cable tendiendo a sacarte de los...
