Does anyone have any experience with Nokia BH-216 bluetooth headset? For some reason my old headset stopped working, so I am looking at buying a new one. I don't have much cell phone knowledge, so I thought to ask the experts before getting into anything. Well, I read many good reviews on this headset and I really like its design. It has DSP (digital signal processing) noise cancellation technology. Can anyone shed some lights on this feature? If you have any better recommendation, please let me know.
