I made a cable today!
Balanced Mini XLR => 2 x 3.5mm
I used some bulk 26 AWG 4 conductor cable, a 4-pin mini XLR female jack, 2 really nice 3.5mm male jacks and some electrical tape. All cables soldered on the connectors. I ended up splitting the cable in half and driving two full cables, once to each 3.5mm plug. In retrospect, I should have bought some 2 conductor cable for those parts, but it’s all right. This was mostly training for my upcoming DT 770 mods.
Tested the cable on the balanced BTR5 output, using Hart’s 2.5mm cable. Sounds great! Now I can use my Sundara with all the other Hart Cables I have, yay.
Soldering the 3.5mm ends was very easy. The mini XLR was a pain, but I also started with it, and I was very rusty (hadn’t soldered anything in a few years). Next time I’ll do better. Sorry, no photos of the XLR, I had to tape it since the cable wouldn’t fit through the back of the connector so I can’t re-open it.
I initially thought I screwed up, because the right channel was breaking up, but it turned out to be the Hart Cable -.- I taped it into an angle and it’s working fine now 
I’ll ask Hart for a replacement, I just got this a couple of days ago.
