Dash vs Dash Pro microphone in noisy environment


I was just testing The Dash with 3.0.1 FW for having voice conversations via Hangouts or Skype. It seems to work with much better quality in quiet environments. But as soon as there is some noise around (eg music in the background), this is clearly hearable to the point that it is not usable in a noisy environment for business conversations.
Is the new firmware using Versant 2.0 also on the old Dash? Or is the advertised “Communicate in all environments” only applicable to the new Dash Pro? Basically, the question is if the Dash Pro (non-starkey, its not available in CH) is significantly better then the old Dash with the same FW.


Need to know this as well!!!
