It is made of a heavyweight, flexible plastic material that is totally waterproof. They fit well and seem true to size. One thing which might be of interest,the paper work only states a 90 day warranty not 1 year. I wish it was a little larger, but is comfortable! They have a deep base. The charging case is very convenient and the touch controls take some getting used to, but all-in-all the earbuds work well. I dont know if Televisions Marquee Moon has ever sounded as taut, dynamic, and punchy as when I listened to it with this little speaker. Ive worn them at least 10 times over the past 2 weeks and theyre holding up well. Again, I wouldnt use it for a closet because it is sturdy enough for a drying rack to hold just about what they show in the photos, but it is not suitable for huge volumes of clothing. They were still there and werent damaged, so I guess whoever decided they may want to steal them subsequently decided they werent what they were looking for.
