I have quite a few neckband earbud sets, but I really love these! The retractable part is awesome. My other ones always have the earbuds dangeling even though they are suppose to be magnitized into the end of the set. With these, you push a button and they zip back up into position for easy storage. They were simple to sync with my iphone, and they have great sound. I only wish the instruction booklet was larger. The print is microscopic and I had to get my magnifying glass out to see where the buttons were. Other than that, this is a great set of headphones. 5 stars
