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?
Not really, no. Designing headphones for quality audio is very difficult, involves a lot of physics, and requires a purpose-built shell. You can try to replace the speaker for a better one, but adding a second speaker will only create interference, unless the shape of the headphones were designed to accommodate multiple speakers. Buying quality extra speakers will probably cost more than buying a whole new pair of headphones, anyway.
If you want to get better audio out of your existing headphones, applying a custom EQ is probably your best bet. Compensate for the lacking frequencies by boosting them, dampen the ones that are too pronounced. You can’t use software to compensate for the lack of frequency range of your hardware, but you can make the problem less obvious.
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.
I just came here to remind you that you are the bomb
You’re the bomb bro
Half the battle with headphones tends to be isolation. If you have decent sounding speakers but bad isolation you have mediocre at best headphones. Typically replacing the ear cups can be an option but adding speakers likely won’t yield additional quality. Unfortunately if the speakers that already are in the headphones aren’t up to snuff there won’t be a whole lot you can do. It’s important to make sure we’re talking about the actual headphones though and not the audio amplifier or the source audio.
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.
First, you’re going to have to define what poor sound means to you. Modding your closed back headphones to add more speakers isn’t going to make them sound better, but probably worse.
The best way to get better sound is to replace your headphones with better headphones, or to use a better source when playing music. Even better headphones aren’t going to improve the quality of music of you’re playing lossy Mp3s.
If your headphones are crappy, a better source won’t really help. It’s not an or here, headphones make most of the difference. Only decent headphones will appreciably benefit from a good source.
MP3 isn’t ideal but, unless you have rather good headphones, 320kbit/s MP3 is pretty damn near transparent.
IIRC 192 kbps is about where MP3s get good enough that the vast majority of people can’t tell any difference from an uncompressed recording in ideal conditions. I’ve personally never noticed any loss of quality at 128 kpbs.
The point is, we don’t know what kind of headphones or what kind of source OP is using.
These are Chinese headphones with no name. However, they looked impressive and I was foolish enough to buy them instead of the inexpensive Sennheiser headphones which cost about the same.
Sorry friend. I know that feeling. I wish there was a better solution to your headphone dilemma.
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?
