To Friends and Customers of HiFiMAN:
                     
Within the past two to three days, there has been some discussion online about the HiFiMAN Supermini and Megamini that I feel contains misinformation about the technology we use. So in the interest of clearing up any confusion and to make everyone comfortable in their consideration of our players, I offer the following clarifications.
 
HIFIMAN new player Supermini and Megamini: Single thread mode
 
A portable music player (PMP) is actually a mobile computer. There are a lot of portable music players that use an Android or Linux operating system. These systems are in multi-thread mode: CPU executes multiple processes or threads concurrently. Multiple threads can interfere with each other when sharing hardware resources, which creates jitter when playing music. 
 
In computer programming, single threading is the processing of one command at a time. Instead of developing the music player software on existing Android or Linux operation system, the Hifiman team has developed its own embedded operating system. Specifically, HIFIMAN Supermini and Megamini are portable music players working in “single thread mode” most of the time; only some very small tasks such as displaying and button responses are running on multi-thread mode sometimes. More than 95% working time, they work as single threading so that their jitter level is much less than that of an Android or Linux PMP.

About Gapless
 
When a PMP is playing music as gapless, current technology has to play music and read the next track simultaneously. That way it will play the next track as soon as it finishes playing the first track. Therefore, it is a multi-threading process.
 
The current beta version firmware of Supermini and Megamini cannot support Gapless. However, the hifiman team has figured out a way to support gapless playback in single thread processing. In other words, there is no more jitter generated when a HiFiMAN SuperMini or MegaMini player is working as gapless. We plan to launch it in the official version firmware before the end of the year.
 
Supporting Exfat SD card
The current Supermini and Megamini cannot directly run an exfat format SD card however you can format it in the player and support 64, 128 and 256G SD card without any problems. We are currently working on supporting exfat and will support it in the official version firmware later this year. 
 
If anyone has any questions, or would like further information, please contact customerservice@hifiman.com. Thank you for your support.
 
Best Regards,
Fang

No gapless = no sale.

It's 2016!

My Clip+ has been happily playing gapless since 2010.

Fang and Hifiman team, thanks for the clarification and update.
It seems that there is no dedicated thread for Megamini yet, shall we post impressions of Megamini here, or in the Supermini thread? Thanks!

I installed the latest firmware and was able to see the album cover for my songs but for some reason it has disappeared.

I bought a Megamini during the Black Friday/Cyber Monday sale and it was delivered to me last week. The SQ is awesome and I really like the form factor. Initially I was upset as I thought, I got a faulty DAP as the battery indicator goes empty quickly even after a full charge. It turns out that it's a bug in the firmware(Version 2017-07-27. V006) it's shipped with. Updated to firmware V05 (2017-08-22 12:12:00) which fixed that. Still, while the device is in operation, there is a lag to get the screen back after pressing the power button . Also the screen has to be on, to skip the tracks or change the volume. @TeamHiFiMAN , is there a way to change this behavior in the future firmware release. And can you please add more volume steps. The device is very loud and it's impossible to adjust the volume of my liking for some IEMS. So I am using one of those high impedance 3.5mm adapter. Can you please consider these.
