Sony Bluetooth Noise Canceling Stereo Headphones MDR-NWBT20N Black (Japan Import)

hi everyone today I will be making my review of the sony headset it's the MDR that eats seven seven zero the black version of it I have opened it around half a year ago that's why I only have the black box watch which is inside of the original casing it has 40 millimeters never dims driver to mix noise canceling a detachable cord the maximum usage is 13 hours with Bluetooth sound streaming and noise cancelling on let's see what's in the box so the first thing you see a smaller box black box in which you can find the court we have 1.2 meters male male court the three point five millimeters diameter with gold-plated heads the pouch which is a regular pouch nothing special with the red sony logo inside you have a one separation nothing special here and some paper as we move on underneath you will find the headset itself pretty one place as you can see it's a pretty simple headset nothing u
