I bought it cheaply without any difference from the new one. The shipment is fast and the product is very good.
When I turn the noise cancellation, there is a white noise. I think that this is noise cancellation. It is good sound quality. I am going to use it when I am in the health. I will take the noise of the speaker music by noise cancellation and I will listen to the song I want. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
