What types of batteries can be used with the cordless headphones?

Applicable Products and Categories of This Article

The cordless headphones use rechargeable nickel-metal hydride (NiMH) batteries. In addition, commercially available (size AAA) dry batteries can also be used to power the headphones.


  • Do not charge a dry battery.
  • Do not carry a dry battery together with coins or other metallic objects. It can generate heat if the positive and negative terminals of the battery accidentally come into contact with metallic objects.
  • If not using the headphones for a long period of time, remove the batteries to avoid damage from battery leakage or corrosion.
