I have some closed-back headphones that have poor sound. Is it possible to improve the sound of the headphones by installing additional speakers?
How much better can the sound of the headphones be if the cups are covered with soundproofing tape?
Don’t listen to these chumps. More is always better with speakers. I wear my headphones over my ear buds and sync them up. It sounds amazing and everyone says I am the bomb.
Everything about a headphone design influences its sound, not just the driver. If your headphones are crappy, chances are that changing out the driver won’t help much, even if that was feasible which it is likely not.
Short of just getting new cans because the speakers are just that bad, I think you’ll be better off enhancing the sound source instead (EQ, DAC, etc.)
Why are you trying to get an answer via an internet forum instead of in the obvious way?
