I just got an iPhone 4 the other day. My current headset, a Plantronics Voyager 520, isn't working well. The listener hears a lot of static/noise. This headset worked fine on my previous dumbphone. Assuming I just need a new headset (not a new phone), what's a good one to get? People seem to like the Jawbone Icon, but I'd like some real world experience, with people on 4.1 or 4.2. I don't care about fancy features or even noise canceling; I want it to sound good in my quiet apartment. I will use it for talking, no music. Decent battery life would be a plus.
