Bass isn't as loud as I thought, and the sound could be louder. Otherwise it's stylish for me at work and very convenient

Pretty- but pretty useless
Originally had a great experience with these- beautiful, good sound quality. But definitely not to be used for running- the control button unbalances the weight so they shake around a lot & fall out- and 3 weeks in the right earbud completely stopped working for me.

I am a grown woman but I have the tiniest of ears. So I was worried these wouldn't fit, but they do! Very comfy! And I can work out without knocking them out of my ears every 5 seconds.
