Has anyone tried these? Shure Stereo Headset - Universal Keep your hands free and your ears happy with this premium 3.5mm stereo headset from Shure. With a I2c-m in-ear headset, inline microphone and personal fit kit, this headset is perfect for your music enabled phone. (2.5mm adapter available separately.) Can't seem to find anything detailed information on them OR find them anywhere except the AT&T store. I wonder about the quality and if they function the same way Apple's headset does as far as answering calls.
