PHILIPS HEADPHONES SBC hc 8440

Question

I have charged my phlips wireless headphones since 1 p.m. yesterday until 10.30 this morning. I have tried to use them but without success.

I have the ariel, the charging wires, the headphones and a separate adapter with a plug plus a little adapter to link to other equipment.

Could you help me use this product? I am not obviously understanding what does go where other than I think I have charged it correctly as the red
light comes on the headphones.

I am not at all technically minded!
