I’ve seen other earbud cases and in my opinion they are big and bulky. I was pleasantly surprised that it only took me about 30 minutes. Take calls as well. These look and feel great but are too large. My kids lost my beats earbuds and these are a great replacement and comfortable. I really like this simple product. Edgy design. Because of the dissimilar radii, you will not be able to sand from the bottom to lower it. The cord is long so I can reach the printer without taking them off. Can’t fit a binder in it.
