Sony MDR-NC7 mod

Hey guys im new and not sure if this thread belongs here but ill go ahead and tell about my find.

So I have these cheap sony noise cancelling headphones that are close to worthless when it comes to audio quality. I decided to open them today and take a look at the internals. What I found was a large sponge covering the drivers.

I removed this sponge and also removed some tape on the back of the driver. This was a white rectangular piece of tape that opens up an airway into where the driver is. I reassembled the headphones and found an incredible increase of bass from my equalizer and a more neutral feeling without the equalizer.

If anyone else owns these headphones they should try it out and share their results.

Thanks, that actually helped so much. Now the headphones are at least acceptable to listen to, still a waste of money imo.
