The AWOL Vision DLP Link 3D Glasses 2-Pack are specially designed for projectors with DLP Link technology. However, Sony projectors, such as the VPL-VW270ES, use a different technology, namely XRMD (Xilinx Real-Time Video Processing) or often Sony's proprietary 3D technology, and not DLP Link. Therefore, these glasses are not compatible with Sony projectors such as the VPL-VW270ES. For Sony projectors you need specific 3D glasses that are designed for this technology.
