Left side of headphones significantly quieter than right?

post #1 of 12
Thread Starter 

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.

Maybe the cable doesn´t make good contact somewhere?

Which cable? I checked everything internal and external and still no luck :/

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?

With IEM  , when a side is more silent than the other, it's often that the holes are obstructed.

Maybe this is the same for the full size headphone, just suggesting.

Which holes would you be talking about?

 If they are opening  in the side of your headphone, maybe some dust was gathered there.

You could try to use a compressed gas duster to get rid of it.

 

Otherwise just compare physical  difference between left, and right.

I broke them down to practically just driver's the other day to eliminate anything and it was still happening. Starting to think it's just a blown driver :/
