Hello! Let's talk about the model akg k 495nc. I know that it is not yet widespread, but I'm very interested to hear a little about this model. And your opinion about it. I'm curious to know about the quality of its sound and power of the bass. well I'm interested in noise reduction system. it goes in a separate box that connects to the headphones? or is it built into the headphones themselves? Thank you all for helping the development of this theme.
