I thought I’d have to order another set, but I was able to fit all of my spice bottles on the shelves, you can fit at least 8 normal size bottles on each shelve, more if you have the small square containers of spices. They stay that way even when you’ve worn them all day! But this automatic volume control means a software geek somewhere has decided what volume I ought to be listening at, based on what the software thinks of the background noise. Charging: The case charges the earbuds from "low battery" to full in about an hour or so. 5, ordered a 9. excellent trainers, great sizing, good comfortable fashionable style, and good wear. next time i will go wired. If you’re considering these earbuds, I thoroughly recommend them based on my experience. Like previous Sanita clogs I have owned, these are excellent quality. Once I adjust the toe and heel straps, I dont touch them again.
