No squelch, VERY LITTLE echo, I could hear voices clearly. I cant believe how super lightweight these sandals are. Worst $12 I?ve ever spent. If I got my regular size, no issue getting them on, just too much room in the foot and once the fur was mashed down, they would have been way too big. And the dark brown stain looks great. Not every Crocs has the same level of comfort. The only thing that could improve this case is if the lid and the case itself were attacked rather than in two separate pieces. Believe it or not, in the video the guy did not set it on correctly. Ear canals are shaped differently. I was able to glue some slick pads in the bottom of them so they will work for my event where I am dancing tango.
