Open back headphones with bass?!

I found this trick on this blog so hear me out.

Grab a sound splitter, plug your open back cans ex. ad700, hd5xx, akg 2/7xx, etc, and the w.e wire that leads to the subwoofer.

(I like mines gold plated, but I use my fiio since I dont have splitters at home :P)

Now plug those bad boys into your soundcard, dac, so you can see where Im going with this. You may need to adjust volume, eq to get it to your liking.

Go play your fav music now, so you have the clarity of an open back plus the real thump of a sub. Dont puke too many rainbows now.

I'll entertain this, to do this right you would need to use the subwoofer's low level pass. That way the sound can pass through the sub's crossover. :P
