            Superior Audio<\/h4>\n<\/li>\n<\/ul>\n

            BF-TD520 adopts narrowband codec and digital error correction technologies to deliver a better audio experience and better anti-interference. The user can enjoy loud and clear voice communications even in a noisy environment or infringe areas.<\/p>\n

              \n
            • \n

              Silence Unknown Callers<\/h4>\n<\/li>\n<\/ul>\n
