A little disappointing, but still great to wear around the house and yard on my days off. The original order included only one ear but this size so it was better than what I had but still not as small as I would like. I have the JBL true wireless but they hurt my ears or won?t stay on because they are so big. Will reorder in large. I can hand a lot of shirts and light weight pants so it is then easy to grab and bring to my closets. These are flat on the inside, no little protruding ring to fit in the above mentioned groove. There is a noticeable improvement in music IF you are using a high res Lossless track (like Amazon Music HD (added subscription cost). Great gift idea! Aber das ist eine Krankheit, die seit dem Aufstieg der Beats ja viele Kopfhörer plagt. I find flip flops a hazard especially in greece where there are uneven roads and many steps!
