Sennheiser PX200 headphones - no audio on right side in Dakota Crescent, East Singapore for sale

Used Sennheiser PX200 headphones.
Defective - NO AUDIO on right side (left side works just fine).
Extremely lightweight and comes with a protective case.
Ear pads and headband padding have been replaced previously due to wear and tear.
As you can see, even the current ear pads have suffered slightly from wear.
(BUT you can easily find replacement ear pads and padding from Singaporelisted - super, super cheap, example: http://www.Singaporelisted.com.sg/itm/Ear-Pads-Earpads-Cushion-Replacement-for-Sennheiser-PX100-PX200-PMX200-HX50-FW3-/130798938255)
The cable that connects to the right of the headphone (see 2nd photo) is also exposed at the spot where it meets the earpads (maybe this is why the audio is missing).
Advertised features:
