The last moment announcement that the iPhone 3.0 firmware update will finally add A2DP bluetooth support means I can start looking at wireless BT headphones again. At the moment there’s a few contenders on the market, but as of today there’s now one more thanks to Sony announcing their new DR-BT100CX in-ear headphones. While the wires aren’t completely gone, you at least won’t be tethered to your cellphone while listening to music, and the small dongle hanging off the earbuds lets you control playback, volume and even answer calls. It’s also recharged via USB instead of some proprietary cable, and you can expect to get about 8 hours of use between charges.
