Hey guys,

I tried to search for similar thread as this one I am going to create, and did not found any posts regarding this solution. It concerns any laptop with integrated audio device and is for everyone who wants to get rid of the static noise of laptops. I will begin with my "story" - I connected my q-jays in-ear headphones to my laptop (Compal FL90v2 with Intel HD audio codec).. there was really a lot of noise disregarding the volume.. no matter what the volume is, there is still the same static noise, I guess because of the electromagnetic "storm" that the integrated audio sound card is not shielded from. Still, the codec sounds quite okay to me - has the power to quite punch the q-jays through and also the sound characterstics are a lot better compared to the ac-97 standard. Except for the noise. The idea is that the maximum possible volume to listen to is something around 20 or 25 %, and if the volume was pumped higher, the real ratio of sound/static noise can be improved greatly. But when the volume is set this high (like 70 %), the headphones are too loud to listen to. So the signalīs volume has to be reduced somehow. For this, a volume element on cable can be used. Like the Shure volume control or Koss VC20. The trick is to set high volume on laptop, and then reduce it via the cable volume control. The result is noise-free sound. There might be questions considering loss in the sound sharpness, highs, or the fullness or definition of bass, but my opinion is that this solution had much more gain the the loss, if the loss is audible anyhow. Consider this as an idea to improve any static noise problem and also feel free to experiment (or to build your own "volume control").. Here are some images for illustration; please feel free to discuss wink.gif
