Here's my recommendation. Don't buy a balanced headphone just 'cus you have a balanced amp. Buy a headphone you like. If it has a detachable cable, then you can upgrade the cable later if you feel you must. It takes a pretty trained ear to distinguish the difference between SE and balanced output, so unless you are one of those types, don't sweat that for now.
As for the balanced DAC input, for those that are confused, it's also another thing you should not worry about unless you are total audiophile and have really well trained ears. Even then, I doubt most audiophiles could tell the difference between volume leveled balanced vs unbalanced DAC input.
Also, don't be confused between balanced input and balanced output. Balanced input (say between a DAC and an amp) is all about the difference between the + and - voltages, and then a ground. That type of balanced cable was designed to reduce interference over long runs, like at a concert between the mIc and a soundboard, or between the amps and speakers. Your DAC will likely sit very near to your amp, so there is not likely to be any EMI. DACs can product higher output for balanced cables since the EMI is handled by the cable better, so a balanced DAC may sound louder; not necessarily better. Since the Jodie has plenty of power, most people (possibly no one) will miss the extra few db one gets from a balanced DAC connection.
Bottom line, get a good headphone with a detachable cable, and use SE it with the DAC and don't worry about balanced unless you have the money to spend on gear. All things being equal, a balanced headphone cable really only adds a tiny fraction to the enjoyment of listening. After all, it's all about the enjoyment of listening, right?
Of course a good part of this hobby for many is simply
