Firstly, for anybody without properly working Rar program, here is direct link to the .bin file https://drive.google.com/open?id=1McDRi_p5XuRAiQTYA5VEL6nnwf9BfSGX Hmm, implementing both standby and shutdown at the same time, will ask if it's possible. We believed that most users have knowledge of their files and what format they are, if not, they can always open the information about the song. Having it constantly displayed on small screen of M0 seemed like waste to us. But it's up to discussion. Yes, tearing was slightly improved in 2.0, still can be visible. I meant, in settings, it's on 4 items and once you read them, you will probably never need to scroll on these again. Song titles, that's different topic, nothing more we can do about them with screen of M0. Regarding charging, if you open any full manual of modern smartphone, it's very likely you will find there similar information. This is from manual of Honor 9: "Avoid using your device when it is charging. Do not cover your device or the charger." Don't think too much about it, it's just standard part of manuals, same as "don't put into microwave". To keep it together with update guide, because as you can see even in this thread, some people have no knowledge how to update. So our hope is, if we will give them guide alongside the update, they will manage it smoothly. More advanced EQ is in the works. We will have clip case sooner than we anticipated Need for FAT32 was mistake of our engineers. Firmware 2.0 fixed this, so in the future, if your device will be already on 2.0+, any update will be possible with exfat and NTFS. What exactly are you looking for? Our system can sort music over album, artist, composer and genre. It will also do album artist, I explained it to our engineers again last week and they will add it in future(apparently nobody in China has any idea how album artist tag works). Of course it also recognizes song numbers, numbers of CD. Enough for you or are you looking for something different? Firstly, when trying to pair new headphones, make sure the other one is turned off. Can you give me more information in Pm what exactly is your M0 doing? On few units(currently about 6 out of 2 000 units shipped internationally), there was problem with screen acting on its own. This is fully under warranty and any unit with this problem should be exchanged with your seller. Please PM me to look into this problem. A) Brand new product released about month ago. B) We put out new firmware 3 days ago and we are still working on other small problems. C) If you still don't believe in M0, I'm sure you will find other 99USD DAPs working better for you. M0 is made from unibody aluminum and quite hard glass screen, we are quite happy with its durability. EQ on M0 is quite basic and we are working on more advanced EQ for our MTouch system. Digital filters affect pre and post-ringing and little bit frequency response. If you want to learn more about them, you can start for example with this article from Stereophile and then spend few dozens of hours reading takes on it from different blogs, audio engineers, manufacturers, etc. For normal users, I will just say, try to change between them to see, which you prefer and if you even hear any difference. Our stock setting is "Minimum Slow" We now have one engineer fully devoted to USB output and he is working on making this playback completely problem free. Tell the seller to exchange you the unit(and if not, to talk to me directly) and please PM me name of this seller. Firstly, M0 has no HiBy Link, also HiBy Link never streamed any music, it was just remote control. If you stream from your phone to M0 over BT, you will use different codecs. On iOS it will be AAC, which is lossy. On modern Androids it will be LDAC, on which Sony claims "Same as CD quality". You can learn more about LDAC here On other devices, it will be basic SBC, also lossy. Combination of USB in and BT out is not currently supported. We make primarily portable music player, not PC accessory.
