Even with those in, the heel strap would not stay on or in place, and my heel still had shooting pain. I would buy again! Of course, none of their comfort matters if the sound quality is crap; normally, I rely on my vehicles sound system to listen to music, but of course, whos driving anywhere? It was very relaxing to listen to Amazon Music HD yesterday through these phones. After install they did what I wanted. The controller popped out again, hit my coffee table and bounced into my tv screen and cracked it. Only negative would be that the lower tray that is supposed to lock in place when this is folded up doesnt have enough tension, so it keeps flipping open. Disappointing having paid so much money. I have pretty much given up my flip flops in exchange for these. I have other Moen towel bars, and this is comparable in build quality. The sound quality is pretty good.
