4.4mm Sony MDR-Z1R headphone. Maybe a USB interconnect limitation? This DDhifi interconnect is pretty good value for it's price. But it does get warm to the touch at the lightning connector end.

Leather case? yes why not? More colours please.

Seems fine on the iPhone 8 Plus.

If you can figure out how to access the PCB, it would be relatively easy to change out the female USB C connector on your own. I believe you can remove the carbon fiber bottom plate using a heat gun to access the PCB.

Not on mine.. but I reckon it will be over time... That's just the nature of small connectors with the constant plugging and unplugging. I would use something like sugru to keep the connection sturdy if you only intend to stick to one connection.

It is drawing close to 160mA from my iPad Pro.

I am sure you like it too. 😉

I've managed to listen to the C9 paired with the WM1Z and Z1R today. I am pleased with the increased dynamics, depth and improved sound signature especially on vocals with line in, tube and class A activated. With pre in, I was hearing more or less the same straight out of the WM1Z...

For anyone who might be interested.

I only see 120v.... no 220v-240v???

不是吧。还有人用SE486? 有没有搞错啊？起码出Z1R先。

Which set of customs have the most similar sound signature as the Z1R?

Not a clean mod from a visual point of view. Did you try to clean it up?

I found a fix to the dropouts. Turn off adaptive sound control.
