Summary: Great to use while exercising when there are other noises around (pumps, fans, etc). One downfall is that I have small ears and even though the size is adjustable they do tend to slip off while exercising. They were bigger than I thought they were going to be but the sound is clearly and do the job that I wanted.
Summary: I bought this for my wife at Christmas and she uses it to listen to her OWN music while doing her chores around the house. No more arguments with teenage daughters about who's music should be playing.
Summary: Great for in the gym or any type of physical activity. No wires to hinder movement and you can leave you playing device in a close remote location and not have to carry it on you as you move around the gym.
