Which rechargeable batteries can be used to operate the headphones?
The RS 175 headphone system is supplied complete with high-quality low self-discharge rechargeable batteries (AAA size, 1.2 V, 820 mAh). You can also use non-rechargeable AAA batteries. Note that if you are using non-rechargeable batteries, you must not place the headphones on the charging contacts of the transmitter’s headphone holder.
