I also notice this when switching algorithms. There’s always that very short interruption of the sound. I have two Cosmos units, and both exhibit this behavior—both with the original firmware they shipped with and subsequent firmware updates. So far, the only way I’ve been able to avoid this is by connecting the two units in series and limiting midstream changes to the first unit. It is indeed frustrating—that doesn’t happen in any of the promo or review videos I’ve seen so far.
