They are truly the best truly wireless headphones on the market right now for sound, but super pricey. It has manual control of volume and mute function. Theyre pricey, but completely worth the money I spent. Easy to put on. I gave her my phone and let her pick out the one she wanted. Work great for my head set I decided to leave that light mounted as a back-up when I dont use the Varia light/radar. Instructions were horrible. The heal is coming up right out of the box and the the tacks they used to tack down the sides of the leather are visible and I can could feel it in the side of my foot when I try the shoes on. there is not sturdiness to it which concerns me as I car electronics in it from time to time
