Hi, after some listening to the m1060 I kinda like it. Can be a bit harsh and sibbelant but over all it's a energetic planar compaired to the HE4xx.
Got the new version with the 2.5 ts cup end cable plugs.
Can any provide a link to a cheap'ish balanced cable 2.5 trrs on AliExpress?
Try removing the grilles and see if the sound is less sibilant. A less obstructive and/or reflective grille does wonders. I personally feel the stock grilles (and the pads) hold these headphones back.
As for the cable, I noticed that the dual 2.5mm TS cable options on AliExpress have dried up recently. That makes the balanced options even fewer. I did a quick search and checked my favorite stores but came up with nothing. I had some luck on eBay, however, so you could try looking there. This one says it ships free to the Netherlands. But I don't know if this length and termination work for you. https://www.ebay.com/itm/2-5mm-BALA...-700-HD700-Audiophile-Headphones/174046118673
