I have and why don't YOU see the LIght for a Change

Again, headphone uses 4 conductors for balanced system but 3 channel jack lures you out from truth that each driver has 2 channel and 2 drivers make it 4

I have tried the setup that you mentioned above, however again u still don't wake up a smell the roses or coffee. You CAN'T use an adapter for a single-ended headphone to a balanced amp because of the fact that you will be shorting out the output stage of the amp by bridging the two (-) channels (-L/R). Using a balanced headphone with a single ended headphone amplfier is possible using an adapter however not vice versa. Do You Understand. If Not then U R truly a Dense person with No Real Knowledge. Reading This Post has Shown Your Lack of Knowledge or Experience.

Please try and read what u post before posting.

I have extensive engineering experience. More importantly I have a great sense of what is and isn't. re-terminating your headphone cables to fit a balanced setup is a must because of the fact the nature and circuit design of many headphone amplifiers today. Even Little Dot states that if you try to use a balanced XLR to single-end "stereo" phono jack adapter with their Little Dot MKVI amplifier, you will not destroy the amp over time, but also void their warranty. I suggest you study audio electronics circuit before using your rather extensive inexperiences to make a rather destructive post or recommendation to other audiophiles (headphones as well). I have been an audiophile for more than ten years and I have been into headphone for a little more than that and have not heard something this IDIOTIC in a while. If you are going to tell someone that this OK, then please think carefully before saying what you r posting, because you r going to lose in this argument.

Here's how it looks like for jack and cable using balanced adaptor to balaned system.

-------------------(L+)-------------->
G------<-------\______2cm_/(L-)<-----------
Balanced(10cm) ------G<---- Headphone(10ft)
G------<-------/_5cm______\(R-)<-----------
-------------------(R+)-------------->
___________Adaptor_______Jack

G is just a come back from + phase so it doesn't carry sound for listening.....and it works well, friend
When plugged into a single ended amp, g is just a passive come back from a + phase, BUT WHEN PLUGGED INTO A BALANCED AMP IT IS AN ACTIVE INVERSE SIGNAL COMING FROM THE AMP.
The ground wires are used differently in balanced mode: they are used for active (inverse) signals from the amp to the drivers.
These signals are different for left and right channel and CANNOT BE COMBINED IN ONE CONNECTION!
