    Copy update file to a blank memory card and start updating - the card should only contain a update file.

    Why does the battery show up as discharged when you use it, then fully charge it and then it doesn't seem to update right away so it shows as red and discharged but the battery is really full then? If you plug it back in, it then starts to "update" the charge state. and fixes it but it is still wrong for a while. Firmware 2.1.

    looks like you got the faulty unit

    Is there the possibility of using the M0 as a Bluetooth receiver and outputting the audio to listen via external dac/amp?

    Currently this is not possible.

    Any suggestion about an iem that pairs well with m0 in order to have an open and neutral sound ?
    I was thinking about fiio f9 pro or Ibasso it01

    Hi Shanling,

    In HIGH Gain Mode, what is the max impedance your M0 device can drive?? Please let me know in detail.

    Thank you!!

    Depends on the sensitivity of the headphone as well ie the db/mW it outputs.

    Ok so 250 ohms and 102 dB/SPL (1mW/500Hz).

    Please let me know for High Gain mode what is the max it can drive.

    Thank you!!!!!

    Bummer. This would've turned the Mojo into a virtual Poly Mojo.

    Hi @Shanling.....feature request for the M0 to be able to be usd as a transport into a dac/amp outputting audio received from Bluetooth, along with AAC Bluetooth transmission. Cheers.

    That would be a maybe.

    Initially, I was going to say now, or not really, but then I connected LCD-MX4 to M0 right now to do a test for you, and I am quite happy with the music, it can drive some headphones well. from you descreiption, you're trying to drive Amiron, by any chance? that requires more power than Mx4...

    Hey George!

    I C. No I'm driving my 250 ohm Beyerdynamic DT 1770 Pro (102 db/SPL sensitivity).

    I just a bit ago found this review by Headfonics (see excerpt below) which basically proves it can't handle 250 ohms. So I think when I upgrade my LG V30 to my next phone (which very likely won't be an LG with Quad DAC) I will have to instead buy the Ampio G1 VD-6880, which can most definitely handle well over 250 ohms.

    Driving Power

    The specs say it is recommended up to 300ohm and I intensely disagree with anyone recommending anything that difficult to drive for usage with this M0. It struggles with 120ohm and does not have nearly enough power to do justice to needy headphones. Stick with typical portables, 32ohm and under, maybe even up to 80ohm and you should be just fine.

    Thanks so much anyway!!

    The Ibasso is a great match.

    Unfortunately it seems that that headfonics reviewer does not yet understand that it's the sensitivity/efficiency that matters more than the impedance (as well as whether it's a closed back, open back, or iem).
    The M0 can drive the Pinnacle P1 which is rated at 50-ohm and 96dB/mW (which equates to 109dB/V) in low gain. Your DT's 250-ohm and 102dB/mW converts to 108dB/V, so the M0 should be fine at driving it in high gain
