The treble and mids are good. these vibrate on your head and it takes some getting used to, but that is what the tech is supposed to do. That said, I would highly recommend both the ANKER Powerline+ II and Powerline+ III series cables, as both come with ANKERs lifetime worry free guarantee. A great investment indeed. Volume can go loud with the right settings. It can last 20 hours playing music in outdoor. I bought uv beads and put them in with my stuff. Another pearl broke off when I barely put pressure on it. I don?t wear my ear pods without them. I like everything of this.
