Why is Bluetooth Connectivity Better?
Earphones included with most MP3 players are not one size fits all. What difference does it make which pair is used – they all hurt. It is impossible to get a pair of earbuds to stay in when your ears are smaller than those intended to wear them. Then there are the wires that get tangled in zippers and flop around when exercising. I have tried wearing the cord to my iPod earbuds underneath my shirt in the summer and my jacket in the winter. As long as you are within 33 feet of the MP3 player using a Bluetooth adapter and a pair of Bluetooth enabled headphones the music should come through loud and clear. If there is some kind of interference the distance may be less however.
