They fit true to size (im a 5. I am usually a size 10 and have wide feet. I have the JBL true wireless but they hurt my ears or won?t stay on because they are so big. No rough edges or misalignment. As soon as ya turn on the noise canceling there was a lot of static and crackling sound jbl is good brand just not this model My foot seemed to dominate the flip flop, looked weird. I believe this is an excellent purchase based on the duration I can use these strips (the rest of the strips are still sticky). If you can get by the ugly they are very nice and fit perfectly ?? They look great but are super narrow. Still took my chances and I purchased mine.
