I own another pair of Gucci sunglasses from a retail store and these came to me in the same packaging. On the first trip it rained heavily on our drive there and all of the items in the bag were completely dry when we arrived. Best pair I’ve ever owned. Im certain my experience is unique in this regard and I would not be concerned about a shifting phone if you are considering this unit. I dont plan on doing it right away but as these shoes wear more throughout the Summer months its a nice option for an even more casual look. The audio quality is abysmal, I tried it with windows sonic, I tried it with Dolby Digital, and I tried it with ICUE native software. This speaker is somehow extremely loud and clear - I still go to clubs and this thing is loud ok? So dont come up with your relative/subjective/it depends on this and that thing. Great slides for my son, true to size. He plays at least two hours of tennis 5 days a week, but these are not well made shoes. I only wore them to take out trash maybe 100 feet every other night .
