I love this product! I have small ear canals, alot of products for the ears hurt me, this does not. It is a bit heavy once you wear it for a while, but has a high comfort level before until then. There is an annoying blue light that flashes all the time when it is on. I like to use this while I am at work (at a school- on the play ground) to listen to music with one ear and the kids with the other. Works out great until someone notices the blue light. Since it is always on, I can get away with saying "that just means it is on." It would be nicer if a flashing light did not draw attention to the product though. I also wear glasses and driving at night reflects the flashing blue light off my glasses. Which is very annoying.At random times while I am listening to music I will get static. My phone is in my pocket, not too far away. I do not know why it does this and it will stop as quick as it starts. The blue light and the static are the only two things I dislike about this product. Overall I am very happy with it, and due to my small ear canals it is very hard for me to find a product like this that I like.
