Doug, how is the fan on the Delta 3? I haven’t tried the River 2 but folks here don’t seem to notice the fan being a problem. My Delta Pro fan can be obnoxious but not as noticeable for steady loud music. I seem to be more sensitive than others to these kinds of things too.

Just so that everyone understands their options with how these can be used, my unit stays plugged in to the wall 24/7. The performance is exactly the same plugged in vs unplugged.

Even plugged in to the wall, the components are still powered by the EcoFlow battery. The only time noise is introduced is if the internal charge starts during stereo use. In the event that this happens, there is a buzz that occurs. If this happens to me during play, I go into the app and jump the recharge limit level down.

And I have yet to ever hear a fan come on with mine.
