I love these headphones. I am on the subway and I love that they give you different sizes to fit your ear. That way you can hear your music not another persons conversation. You also, don't need to put the volume on high, therefore you can save yourself from growing deaf and you can listen to your music clearly. One important thing..You have to be careful when you take them out of your ear. Don't pull them out. carefulful take them out with your finger tips from the ear. If you pull it out then you will separate the ear piece into two.
