The first thing I noted when I received these headphones were that they were very flimsy. They feel cheap and unsturdy. The second issue was that the ear pads are very small. I am a 6' tall male, and the headphones fit very poorly over my ears, leading to an uncomfortable fit.The third issue is that nowhere in the product description is it mentioned that these are IR as opposed to bluetooth or RF. This means that you may only use the headphones when there is a direct line of sight between headphones and transmitter. This is unacceptable, and it should be mentioned in the description that they are IR. All-in-all, I am going to try and return these to Amazon, and avoid any future Sony wireless headphones.
