So I've had my set of Astro A40 headphones for over 3 years now, and just over 4 or so months ago the went on me :/ So Thanks to the community here, I got myself a pair of Sennheiser HD 518s and love them, but It got me thinking as to what may be wrong with my A40s. So I popped them open and there appears to be no physical damage. No holes in the driver, no burnt or ripped wires, nothing! But the left side is a LOT quieter than the right. It still plays audio, but very quiet and sorta muffled. Any ideas on the cause of the issue, and / or fixes? I am not opposed to any soldering, so any advice is appreciated.
 
EDIT: It's also almost as if it's lost its mids and highs but retained bass.

Softer sound are not contact related. If the contact is off there is no current so there will be no sound. I do not think the following is related but can try. When I first got my MS2i, I realised the right is always softer and when I shake it, I can hear something rattling so I open out and check. I realized the magnet on top of the speaker driver (button looking thing?) was loose. I press it down and indeed the volume are now balance. They was hold on by epoxy so I apply some epoxy to fix them in position and they are all good ever since then.

Are you plugging the headphones all the way in? does it happen when you plug your headphones to a different source?
