"The Samsung Bluetooth Stereo Headset (YA-BH270) looks like a regular pair of over-the-ear headphones, except there's no audio cord to plug into anything. Samsung's YA-BH270 works off a rechargeable integrated 150mA lithium polymer battery that gives you between 6.5-8 hours use. In standby mode the headset remains active for about a week on one charge (or 240 hours), the battery is charged in about 2 hours via USB cable."
