Not in my trousers, but a 11 mm thick D-zero + DX50 will definitely fit in my coats pockets. The pico slim would be another option, if it wouldn't be so darn expensive -_-
It does feel a bit useless to not use the dac section of the D-zero, but maybe one day I will buy one of those android phones that connects to its dac.
Pico Slim is made for ciems, it would make sense if you could buy it. I know the price is an issue but think about it, will you ever go back to full sized cans?
Honestly, I will not. I will stay on the ciem world
