I am only keeping them as my bed frame comes very low to the ground and I have not been able to find any containers that will fit underneath. These controls work the same as almost all Bluetooth earphones so you should have no trouble learning the system. I recently purchased a This is a nice full size tailgate bike rack that can easily fit my 4 family bikes. I tested it with three other devices, and the mic is just garbage. I found one of these mystery items sitting on my kitchen floor (where I unboxed the package). It charges really fast. This is an amazing device! I have tried several, some inexpensive and some high-end shoes and these beat them all. And at $25 they are a bargain, even though they wont last as long as some of the more expensive sandals here.
