Philips Vintage Jogproof CD Player Bundle 40 ESP model AX 5011/17

Philips Vintage Jogproof CD Player Bundle 40 ESP model AX 5011/17. This CD Player is in excellent condition visually. Only one is Philips brand. I am not sure how to open the battery lid on it because i don’t want to break it. I’m not sure if it works either because i don’t own headphones with the audio jack anymore. From a pet and smoke free home, reasonable offers accepted. I am unable to tell if they work but it is a great addition to anyone’s collection.
