content: I have an old pair of headphones that had separate volume sliders for each ear. seeing as this is annoying i modded them so that both ears use the same volume slider, leaving one slider unnecessary. I could remove it but that would look funny so I had the idea to add a bass amp and use the extra slider to control it. the problem I have is I have no clue how to design one. I am looking to make something like Skullcandy's skullcrushershttp://ca.skullcandy.com/shop/skullcrushersso if anyone has a pair the schematic from that would be excellent, pictures with enough detail to reverse engineer it would be the next best thing.

content: I think that your moding may have removed any stereo sound that the headphones had unless each slider had two variable resistors in it which I do not think it would have.

content: I think this is an experiment not worth doing. Me personally, I don't give much thought to my headphones. The only time I wear them is when playing games that require me to know where noise is coming from for an added benefit in multi-player FPS games. Other than that I have never cared about headphones. I just want them to make noise, noise that isn't scratchy and noise close to the intent of the sound engineer and that is it. I have a feeling most here won't care either so doing a quick search all I can find is reviews on the above said headphones but no one modding them. At the same time, a lot of people here probably don't own them as there are a billion headphone choices out there. GL

I've found that setup in several different pairs of headphones.Quote from: wilfred on October 31, 2014, 02:10:21 am"Beast by dre" are more $$$ than I can afford, the other thing is most headphones made these days only last for about a year, mine are very sturdy and all ready way older than I am, so making these sound how I want and having them last seems like a better plan than buying a pair of $250 headphones that will last a year.as for driver size how's this:https://twitter.com/EvilGeniusSkis/status/528310773697609729/photo/1Quote from: Bassman59 on October 31, 2014, 05:19:57 pmthat approach only works in certain situations, for example, on an iphone the EQ only effects the native music app, not Rdio, youtube, web browsers or any other source of sound.
