I tried this headset for 2 days. The first day, I thought I would like it. However, the second day, I couldn't keep it on my ear. The earpiece swivel had loosened so much that it would twirl around too easy. Every time I moved, the earpiece would slide and the headset would practically fall off my ear.Regarding the advertised noise suppression, I don't think it exists. I previously had a Motorola H500, which doesn't advertise noise suppression. My callers would say that this headset was worse that the old one. Any wind at all, and the caller would not hear my voice.I returned this unit.
