Sonos Roam vs JBL Flip 4 (Patreon)

I found my old Flip 4 in the cellar and thought it may be interesting to hear how it compares against the recent Sonos Roam especially for casual listening outdoors. I am not sure the Flip 5 sounds that much better than the Flip 4, because when I had the chance to compare both in a store I was not that impressed and  never really considered getting one, but kept the Flip 4 instead, although I haven't used it for quite a while.
