These are best in quality and budget friendly and have only just 300 from amazon and the only disadvatage is to light from the side passes and have the headset is equipped with Full HD display ( 1920x1080/1.03 megapixel per eye) . The sharp picture is projected onto your retina through the aspherical lens without distorting the image, allowing every pixel to remain in sharp focus. I would like recommand this for just know about the device but there are also device which are best.
