Since this is balanced, If I have a 4 pin balanced cable what does the other end that goes into my HD598 headphones look like? I would eventually need a balanced to single end converter no? ( The two wires that go into the headphone)

Yes this reeks of headphone noob!
Hi!
I'm a little confused by your post. I think after reading it over a few times, you might be confused as well
. I'll try to help, sorry if you know what I am writing already.
'Balanced' amplifiers and 'balanced' DACs are a whole world of issues I don't want to jump into.
Let's look at 'balanced' headpones. The headphone itself has 4 connectors total. 2 connectors in each earcup, one for positive the other for neutral. All standard headphones take neutrals and they are tied together at some point to make 4 wires into 3. This makes the ubiquitous
TRS connector, which has 3 connectors on it.
This happens in two locations:
1. If the headphone has a single wire coming out of one cup (like the HD598), often the neturals are tied together in the cups and three wires come down.
2. If the headphone has wire coming from both cups that join in a 'Y' (like the sennheiser HD650), often the wire at the connector contains all four wires. In a few rare instances, the single sided wire will contain all four wires as well.
If you are in the latter group, making the headphones 'balanced' is rather easy. You can cut off the connector and install a 4 pin XLR (see
here and
here). The kind that goes on the headphone is the 'male XLR', and the connector on the Mjolnir will be the 'female xlr'. The other type of connection is using two '3 pin XLR' connectors. I won't really touch on this, because really most balanced headphone connectors now just use the 4 pin xlr. (No disrespect to the design of the Mjolnir design. I understand why this was added in, but for brevity's sake, I don't want to get too much into it).
If you are in the former group, you have to rewire the whole headphone. There's different ways to approach, but basically you need to add a new wire that will run all four connectors down.
Whew, I hope that helps a bit. I'm not sure which category the HD598 fit into. I can't find any service manuals, so I'm not sure where it falls.
