Great for Zumba!
I don't know how I survived my Zumba class for so long without these! I love doing Zumba, but they play the music REALLY loud, like club level loud. These are barely visible, and they stay put, even while you're flailing about doing your most exuberant dance moves!  I don't feel like they act as a filter enabling you to hear conversations very well.  But I think that may just be because I already have bad hearing. If you want to chat between songs just pop one out. They are easy to put in and remove.  Protect your ears people! These are great!
