Hi
@hqssui, welcome to the conversation!
The M3's command dial was never accidentally turned in my pocket, so as long as they maintain a similar level of force required to turn the dial I don't think it'll be a problem.
The only issue I had with it was not pressing it quite straight in for Play / Pause would sometimes cause songs to skip forward or back. Once I got used to it, that was a rare occurrence, though. It looks like the M2 will solve that issue by putting Play / Pause as the top function on the joystick.
I am happy to see that joystick functions are now printed on the command dial and that FFWD / RWD functions have been mapped to L / R on the joystick instead of Up / Down like the M3. That was quite confusing for me with the M3 (and Cayin N6).
I'm curious if the rounded center on the M2's command dial is a button and what functionality it'll have.
I'm also curious what kind of outputs the M2 will have, since none of the pictures show that.
And I'm hoping (fingers crossed) that M2 (and M3) will have 120 volume steps for more fine-grained volume control. Fiio changed from 60 to 120 awhile ago, and I really appreciated how easy it made finding just the right volume for all of my HP / IEM.
(Im)patiently waiting for more information
