So you are much better off ordering your normal size. The cross bars are ok but the pieces that go into the rail give too much in my opinion. The authors in this book do a high-level overview of what tinnitus is, what the causes are, and then go into cognitive-behavioral therapy (CBT) techniques on how you can learn to live with the condition and manage your response to it. I will say that the separation is really good, much better than what I have on my regular airpods (Not as good as the airpod pro?s, but those are also over $100 more expensive). Normal crocs size 8 are a nice roomy fit on me. I always do this with shoes. You can also use the app to adjust the sound eg base/ trebile/ mid range. I chose this one because it has a built in watch charger, so there is only one USB-C cable plugged into the back of the unit. My quibbles and why I subtracted a star. It?s uncomfortable immediately after putting on so I could not imagine trying to walk around in them especially during the summer.
