What types of batteries can be used with the cordless headphones?
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.
IMPORTANT:
- 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.
