I decided to purchase the SafeRest and was extremely happy that I did. You really cant go wrong with these! Sound quality is what I wanted when I purchased these JBL CHARGE 4 Pair. Just put these slippers on half an hour ago. theyve almost worn out: the tread is almost gone in a couple of areas on each shoe, so traction is much less on snow/water, and their days are numbered. They last me a few days In between charges and I use them for hours on end. Would be super rad if they invested a couple more bucks in an amp. Great customer service there. I actually found this to be somewhat annoying as when you adjust them in your ear you will almost definitely pause them. Awesome and the wife?s happy to have some thing to hang clothes on in the small laundry area
