    a. To collect your kind suggestions regarding the sound quality of K3 when comparing to the E10K and Q1 Mark II;
    b. To kill any potential software bugs or hardware hidden troubles with your comments before it goes to mass production.

    I know you want it a bit universal across all model range, but when it's for desktop use.. Gimme more robust balanced port please.. 2.5mm is just... Brittle.

    Forgot to put down the headphone once, stand up and there it bent.

    The pull test of earphone socket has been done. If 2.5 cable is pulled up, K3 will be removed together, because the k3 is very light, not a heavy desktop machine.
