Hello, thank you for your review. We are sorry that the headphones do not suit you. Most customers are satisfied with the sound of these headphones, among other things, and the priority is just the perfect ergonomics to keep the headphones firmly in place and at the same time to be comfortable for everyone thanks to the flexible silicone hooks. If you have problems connecting to your Windows 10 laptop, be sure to install the original and latest version of Bluetooth drivers from your PC manufacturer's website and the connection to Intezze CORE will work great, we've tested it. If you need anything, write to
