Are there any sound processor differences between Roger On In vs Roger On In V2? I know V2 will do more with Zoom and you can connect multiple mic’s, but I’m not overly interested in either of those features. I can find the older version for $200-300 less, but if the V2 will clear out more background noise it would be worth it. Phonak Paradise Audeo P90-R hearing aids, so I want the In version.
