If you mean not turning on, this may be from worn out rechargeable batteries. Rechargeable batteries have a limited life span of a few years if used regularly. Once worn out, replacement can be easy or difficult; head phones are slightly difficult to disassemble, ear buds and similar devices are mostly sealed and not serviceable, often cracked open like using a nut cracker. Cracking open sealed devices may not be repaired if shell parts are damaged. Battery replacement can be the easiest to replace from online distributors of rechargeable batteries.
