This case works good. they are comfortable and seem to be well made. Just tired of it after months of use, but its a necessary evil for mountain bikes, I guess, so Im stuck with it. Would be great also to hold backpacks or hats too. These things are actually almost perfect for me. The volume is not very loud at all and is distorted. However, it is so convenient for my work. I am sooooo glad I got this! The K KiNGKANG Power Tower I bought arrived 1 month ago. Theres a button for a voice assistant (no long-pressing play/pause) on the right earpad and a button for noise-cancelling on the left.
