When I TRIED these Bluetooth headphones, I was impressed with how ultra-thin and comfortable they feel. The sound quality is crystal-clear, and the wireless connectivity is very stable .The battery life is also great, and I can use them for hours without having to recharge. The only down-side is that they don`t come with a carry case, making it a bit difficult to store them when traveling. Overall, I am very pleased with these headphones and highly recommend them!See full review
