The cable bundled with HD560s is balanced and so is the jack on headphone side. I reckon, it will be the same with HD620S. If that is indeed the case, all you need to do is replace the 3,5mm SE jack with a 4,4mm Pentacon balanced jack and you are good to go :L3000:

...and stupid. What next? A BT speaker dangling from the seat in front ☹️

There is no need to wait for 3rd party pads. Sennheiser's own HD560s velour pads will fit. Unfortunately, according to Sennheiser, this change impacts sound signature. So far, they have not elaborated, what changes and to what degree. Will need to experiment, once demo versions become available...

You are right. My comments refer to the Go Link and NOT Go Blu. I have both and clearly mixed them up. Too much work. Time to go on a holiday :wine_glass::beach:

If only the plug could be made smaller. Had to widen the opening on the iPhone 15 Pro Quadlock case to make it fit. Also, how about a 4,4mm balanced version ? :L3000:

I love the buttery smooth volume knob on iFi ZEN products :L3000: Channel imbalance if any, is at the very beginning of the scale. With the correct gain setting, this is never an issue.

Indeed 👍 I am surprised to see how many people are happy about plastic pads. Not only Sennheiser, but across all brands 😏

Plastic pads - sweaty ears guaranteed :( During the winter months :D

Indeed, he did :)

Not at all. Slider is that part of the headband that slides in and out to adjust headphones to head size. On the 6X0 series, the sliders are metal and hence may be bent to adjust clamp. On the 560s headphones, the sliders are plastic so bending is not possible. In other words, are the sliders...

The sliders, I presume, are plastic like 560s. If indeed plastic, adjusting clamp will be a PITA. Metal bends and stays bent. Plastic springs back to original position. Eventually it will adjust (some) but nowhere near as easily as metal.

Harsh, but some valid points there.
