Bluetooth stereo headphones produce a great advantage over the cumbersome hard wired headphone of the past. Since this technology uses a frequency hopping method and fast acknowledgement application, the connection and transfer of sound is smooth and consistent with no compromise in quality. I’ll be honest and say I have never been a fan of Bluetooth stereo headphones but Motorola’s S305 has recently made me a fan. All of you active people out there can put these headphones to good use.
