I decided between HE400i and the HD650. I got the Hifimans. I find them to be more exciting and overall "funnier". The Sennheisers are softer and somewhat muddy.

It's true that the prices are often a lot higher. Import fees are so high too that it's often not any cheaper to order stuff online. 350 € was a pretty good deal. And if I had gotten a faulty pair from the US it would've taken a long time to replace.

  Perhaps, didn't bother trying. Clearly it should pick up immediately when the power is turned on again or the cable is reattached. This is not the case. Windows recognizes the output device being connected but doesn't start playing.

So, is it just my computer or is there something wrong with the Jotunheim drivers? If my PC is powered and I connect the Jotunheim, I get no sound. Just random spikes of noise. Seems like the Jotunheim needs to be connected via USB before powering on the PC. Also, putting the computer to sleep...

Hifimesta, suosittelen! :)

Mine had the same problem. Tried to wiggle the connectors on the headphones and sure, one of them had a problem. Went to the store the next day and got a new pair instantly.

NoisyNeighbour I ordered similar ones earlier and they were a little too tight in my opinion. The dimensions were the same as yours but I was worried they might scratch the paint on the headphones because the fit was so tight. The connectors move a little when you move your head so it rubs...

@sharktopus I personally used these. They fit but protrude a little bit more than I'd want. Though they were still the best ones I could find.       If the jacks weren't offset so much it would accommodate a thicker plug.

Finished the balanced cable for my headphones and now I'm trying to figure out if it sounds any different than SE.  

Made a balanced cable for my Hifimans. I'm yet to test if it sounds any different than SE. The volume difference is huge, though.  

All done!     

  If you aren't going to buy some crazy expensive cable it might be safer to get a few extra meters and then just cut it to the optimal length after braiding. 

Progress made on the balanced cable!   By the way, it was a total pain in the butt to braid the cable. I had four stands of 3,5 m long cables and they were twisted all the time. Took over an hour to do that... I also didn't have any idea that the cable would shrink that much when braided. I...

That's 550 used with a wire of 1,7 mm outer diameter. Works fine, maybe a little loose. Had 3 mm paracord which would've been fine but the material was crappy. 2 mm didn't have a chance. It's better to get bigger paracord, trying to get the wire through a snuggly fitting paracord is a pain. 2,4...

Adapter cable done!
