Every once in a while, MS Teams doesnt connect. The other stupid design is the plug on the end of the power cord is at 90 degrees and slightly larger than most plugs. The Bluetooth ability of all these devices is limited in that when you are sitting on your wallet or there is the smallest obstruction between you and your wallet, the Bluetooth signal is inhibited enough to cause a false alarm. Those headphones were designed for doing sports and they work great for it. I bought two and stacked them on top of each other. Dont mind my dirty earbuds but I just got this case today and so far I like it, havent drop tested it or anything but. Comes with a label saying Not for shower use. These have some cotton at least. I did leave them a little deflated because I new my car would be sitting in 95 degree sun and the air inside would expand. Ordered different one instead
