clam headphones for gaming

i am interested in the clam over the ear wireless headphones in the colour pink from 2-3 years ago second hand for 27 euro. i am not looking for something amazing just something usable for solo gaming. does anyone know if i can connect them to my pc via audio jack (instead of usb) and if the audio and mic work that way? is the audio okay for gaming? also in the images (i cannot attach them to this post don't know why) they look more rose-gold than pink. does anyone know if this is what they look like irl or if its just the camera? thanks for any advice!
