idem for my unit the back panel had little movement ( and impossible to screw mini tork more)   the button are not premium quality for the control panel ( sometime they arn t no efficient and must be used very precisely to  a normal function   VERY BAD POINTS FOR THE FINITION

Have tested DAC BLUETOOTH with HONOR 5X ( spotify/ quobuz hires / youtube)  amazing the last Fw 1.01 is mature ( tactil more reactif / usb dac and btooth ready for use / DSD / great autonomy/ sound quality all in one dap now!!)

hi first  thanks for the support HIDIZS TEAM very fast answer and really  try to solve problems!!! DAC USB is efficient with WINDOWS VISTA ( update REALTEK SOUNDCARD  TO get WDM AP60 DRIVER and now is good) very good player in BT with car system !! AP60 is going to be an excellent dap ...

hi fw 0.06 is online and an other DEDE KILLER V2 ???? what about this fw ???

hi i ve tried to update firmware  / no succees    from  0.04 to  0.05beta     the screen is locked on HIDIZS LOGO and no reboot after 5minutes   .upt file is on root  /  stored on sd cart FAT32 formated on the player ??  do you have the same updating bug like FW0.01??? thanks

hi iv seen a new firmware M2 1.21 on the official website but all in chinese i understand nothind anybody has an other link in english???  thanks

only with .ISO    with wav M2 go down in the wav track list without  error message

same error message   "no file"  and the files are correctly read with foobar or other reader

file name or file too big     i think my .iso 5 2 are more than 3Go and so they aren t read by M2

NO .wav files (high res  24bits)  and .iso  are not read   / i receive the M2 with sdcard and test files and .iso  on the card is read ??

no cue files / M2 BASIC model dynamic is amazing , soundstage and separation voices  are best points too / neutral balance and realism for voices and instrumental sounds

for battery autonomie it s very short !!!  continuous reading flac hires / headphones output /   hifiman HE400S /  max 4 /5 hours !!!!
