This Sennheiser pairs with two devices at a time (refers to them as phone 1 and phone 2), so it connects directly with my BT capable Dell laptop and my iPhone. Fortunately there arent too many instructions and you can get there with a little common sense. They are really cute. I ended up not wearing them for my intended event because I was afraid my feet would hurt with too much standing. However, I ended up putting them in a drawer and using other earbuds. The headset itself feels lighter (not really in a good way. They are nice and comfortable. Since the Company that sold these was SoftMoc you can be assured I wont be purchasing anything from them again. Corkys to size-Not too steep a slope-Toe strap fits snuggly, but doesnt bother a slight bunion I have on one foot. These are comfortable, sturdy shoes.
