I have a chubbier face so I usually go for 59mm+ these sit at 58mm but they?re perfect I also had the older version of the Samsung dual charging station but I had the same issue. I am happy about this ANC feature. Most of the bad wasnt related to the actual use of this cleaner. I bought size 8 fit perfect. I always had great trust with amazonbasics product. The flips are very comfortable, however only available in whole sizes. Wipes clean easy. It holds those tall bottles that just dont fit in my cabinets. If the strap were tight, they would?ve been perfect.
