Even with those in, the heel strap would not stay on or in place, and my heel still had shooting pain. I was very please with the size of the case of the earbuds as it?s nice and compact. In Comfort, they ranked as high as any expensive boots Ive ever owned, fitting perfectly right after the box with no need to be broken in. Battery power seems as advertised. The case is much different than the regular version 3. I ordered the first set and was so pleased I purchased a second set but was really dissatisfied. Its well made, just poorly designed to be honest. Gold pair now siting in my basket. I can fit 4 shirts in each slot! As for range? I have a home office so I?m sitting at my desk when using airdrop and handoff so range hasn?t been an issue at less than 6 feet.
