Hopefully amazon will give me a refund in this. When i first put it on it fit like a comfortable glove. Ce sont de loin les meilleurs earbuds bluetooth que jai essayé et meme meilleure que les Airpods ! A must have IMHO. I wear a 9w usually. I have gone through so many shower speakers, I needed something that would last me. Very warm, very comfortable. In less than a week, the insert on the left foot started to bunch up and over a short period of time, came loose up to the heel. It broke on its 3rd use, and my kayak about fell off of my vehicle and nearly hit the pavement. Craven is.
