With some devices we did have some issues connecting to them. But others we didn't have any at all. So you just go to figure which phone or ipod works the best with it. It's great to have wireless headphones like these because they just clip over your ears and they are out of the way. The sound quality is great and its wire free so there is no getting in your way. The volume control is right there on the cord. Everyone likes them and wants to know where I got them. They are also great for when you are working.
