The buds fit my ears very well. No uncomfortable feeling or difficulty keeping them in my ears even when listening to music in bed. The zipper part of the bud is completely useful, no tangling. The Zipper idea (i.e. no tangling) is probably the best thing since sliced bread. Did you hear me? NO TANGLING. I am completely enjoying the Zipbuds JUICED 2.0. Thank you for the new idea. Glad I found you.
