I tried it again with the Sandisk card and started on track 47. I counted the tracks and it stopped and locked up on track 54. I rebooted and started on track 54 and it again locked up later in the track. I thought that the connection to the DAC might be the problem so I tried with earphones...

I don't know what track it stops on because it reverts back to the middle of track 22 even though it was on track 50 something. Since there are a lot of short tracks with the same theme I don't know exactly what track it stopped on. If it were pop or jazz or even a symphony with 4 tracks then I...

I switched the EVO in the M2X with a 128GB Sandisk Ultra in an older FiiO player. My M0 also has a 128GB Sandisk Ultra in it. It might take several hours of listening to see if it happens again. It has happened recently but it seems to have been worse yesterday. This never happened the first 3...

You're right, removing those few files would be easy. However, listening to the entire 2.5 hr ballet again to see if it happens at some random spot is the hard part. As I listen to other music over time, I'll note if there is a problem only with folders with some certain characters. I'm still...

Thanks for the tip. The folder is for a Tchaikovsky ballet and some of the files have an apostrophe ( ' ) in the name, but that's not really unusual. Do you think that this would be the problem? I'm wondering if the old EVO card is a problem. I've ordered a new one and I'll try that. I'll also...

I don't know if it matters, but the folder I was listening to today had 63 tracks. After I posted the above, the M2X locked up twice when I tried to start playing again. I rebooted and then it went to the middle of track 22 both times. I was on 50 something both times. I also got a brief no TF...

I've had something strange happen 3 or 4 times now. I think it's always been when connected to my DAC, but I'm not sure. The M2X will stop playing by itself and the screen will turn on. Then if I press the play button it will start playing, but at several or many tracks back. This is in folder...

Sorry, I didn't look carefully enough. I understand USB Audio Output and Output Options, but not the first 2 above. I would guess that USB Mode is DAC and I think I read that DSD Output Mode is DOP, but I'm not sure if that's correct. Still need help.

I want to connect my M2x to an external DAC using USB. I plan to buy a Topping DAC that uses USB B. I'm getting an OTG USB C to USB B cable. I'm confused about what settings I have to make on my M2x to make the connection. I see settings for USB Mode, DSD Output Mode, USB Audio Output and Output...

Thanks for the quick reply. I don't know what FW version it was on when I initially charged it. I unfortunately forgot to look before I updated to FW 2.7. I think that the battery may have showed 99% after the update, which is the first thing I did after I unplugged it from the charger. I'll see...

I just received my M2X today and I have found a couple of strange things. The first is the initial charging. Using a 5v, 2a charger the M2X would only charge up to 97%. I unplugged it and plugged it in again but it wouldn't go above 97%. However, after unplugging it again the battery charge...

Oh, true of course. I'm not saying that the CP145 is better for anyone but me. I'm just saying that it seems to fit my ear better. I'm just happy that SpinFit makes different designs and sizes.

I would think that the difference would be more because of the fit in the ear. The CP145 is more bullet shaped. That's the primary reason that I use them.

I switched from the CP100 L to the CP145 L for both my FA1 and FH1. The CP145 fit a little better in my ears and a bit less tight on the stems.

That's the one that I got back in January from SHENZHENAUDIO, fulfilled by Amazon USA. It's still available for $6.99, but the photos don't have the extra tab like yours and mine have. I assume they're just old photos since it's the one that I bought.
