The sound is perfect, and when kept at a low, comfortable volume, I was able to hear everything around me and what everyone said without any hassle. Go in with some patience and will to do a good job. The design and quality of the cords will make tangling nearly impossible, and even if it does, it should be easy to pull apart. Hope this helps you guys. These were lightweight and comfortable to wear. These shoes provide me with the comfort and support I need. I love the fitflop slide sandals for comfort. Wouldnt recommend. The real kicker for me is the extremely poor bluetooth connectivity of these. I just received the shelf.
