Sony Ericsson's HBH-IV835 is a stylish, comfortable Bluetooth 2.0 earpiece that's well-suited to a corporate environment. The smooth, glossy finish looks great and it's light enough to wear for a couple of hours at a time. The unit doesn't feature an ear hook, but this doesn't affect comfort: sure, it's not going to be too sturdy if you plan on jogging with it, but the earpiece remains well-attached in general.
