Une fois quon a un peu déchiffré les instructions, cet appareil est une vraie bénédiction. I hope the person I give these to, are happy with them. Then I looked inside of the hinge from where it connects to the headband. Followed the instructions but it was not easy at all. I have the 1st gen Sony ANC headphones. The ANC is good and works as advertised though babies shrieking or sudden noise changes will only be minimized. ), broke into us! LOVED all my other Moden products I purchased with this order but this was too large and I coldn?t do anything worth itI HATE having to go to Kohl?s to return things so I just lose the money because of my dislike for the nightmare of returning to Kohl?s. Thats so great compared to my beats. Its much more shinier than it looks in the pictures provided.
