To be honest I change them every few months. I haven't found a more comfortable in-cushion speaker than this, but they're cheap, I don't mind, and I always have a spare. I have to sleep with a pillow speaker and listen to my comedy shows. They were made to attach to a headband but I bought them as is. They are very fragile and usually last about three months. I've tried many different pillow speakers but these are the best for comfort between my ear and my side pillow. What breaks is the wire, usually after three months. If this company could do the same with better wire I would give them five stars.
