I can use them in the bedroom by just pushing a button on the earphones which allows me to switch to another frequency. So far, so good -- Tho I havent used it yet. Id buy this case again and again. These slippers are advertised as a mens size 9 - 10. These relationships all come together in a very modern way, with all parties (including the kids) fully informed and in agreement. Some things are just better served by physical switches and buttons, and Jabra got the E85hs controls mostly right. I will say that due to the very wide beam with this light, you will be very visible to drivers. As others have mentioned, the length is adjustable but the height is not. Even though I bought the wrong size slippers, I feel that these slippers were nicely made. The more that I listen to these, the worse they are.
