Q: Can you skip and go to previous tracks?

A: Yes, you hold the volume up to skip, and the volume down to go back.

Q: Can the part that goes in the ear (not the ear cussions) be remove or changed for a smaller on?

A: The cushion can be changed. However, the curved part along with it can not be changed.

Q: are these water resistant?

A: No they are not but good against perspiration.

Q: Why are the buttons incredibly difficult? Why can’t I hear when using my phone? Why do these suck so bad?

A: We're sorry to hear about your experience with our UA Sport Flex. Please reach out to our Customer Support so we could help. https://www.jbl.com/support-contact.html

Q: How can I get the volume on the headphones to rise more? I have followed the instructions but the volume still isn't high enough. I had a set of LG Tones and the volume was adequate.

A: You may have to remove the cushions and ensure there's no buildup on the little speakers. I experienced this a couple times.
