Query: great deal with some quirks

Pairing the 510 with my Motorolla E815 was a breeze. The sound is clear, headset is comfertable to wear. Initial static problems were solved by Verison with a software update. The Plantonics tech rep also recommended that the phone and headset be on the same side.Cons: Talking in any wind causes complaints from those I am talking too. The voice commands do not always work as well as my wired Plantronic headset. Most of the time the voice commands work ok, but there are times when the voice commands will not work at all, and others times I get a responce with a completely different name than I requested.
