OLLO Audio S4X (Early Model) Functionality confirmed. Highly regarded by engineers, especially for its clear reproduction of vocals and acoustic instruments, I was using it until recently for arranging and mixing. The ear pads are peeling. If you are considering replacing the pads, please replace them with the official replacement ear pads sold by the manufacturer. Includes original cable and original bag. 【Brand】ollo audio 【Model】S4X 【Type】Over-ear 【Color】Brown 【Materials】Wood, Metal Thank you.
