Review: Aprender a usar todos os seu recursos demanda certo tempo, mas vale o esforço. Robusto, moderno, completo para os audiófilos que querem excelência sonora.
Review: GREAT product! Downloaded 200GB+ FLAC files and at least 50GB of Spotify music to 1TB microSD over Wifi using SyncThing and Spotify, drained battery by 45%. This is incredible. Took a nap while it finished downloading a couple dozen GB of FLAC files on the charger, was cool to the touch and fully charged when i woke up several hours later. Spotify CANNOT be used while downloading files to microSD card, nearly unusable, even on a high speed card. The music i listen to all the time (using bluetooth, Spotify, Very High) is noticeably enhanced. I have not tested with wired headphones yet, but I assume the enhancement would be even higher. Connects and works well with both my vehicles bluetooth systems (Microsoft Sync and Generic GMC). Today it was 96 degrees F and downloading both Spotify and SyncThing/FLAC at the same time produced noticeable heat, but not much more than my phone while browsing facebook. The system is blinding fast and reacts to button presses immediately. The bit perfect system is very apparent. Very easy to use. I really can't find a reason to complain about this device. Besides maybe not having a GPS chip so I could use it entirely instead of connecting my phone when i need to get directions. But that is not the point of this device. I like the color better with the TPU case on and the warmth of the device when syncing so much data, at the same time, in nearly 100 degree weather would have been a bit much to comfortably hold the device for a sustained period of time. Storage capacity is adequate for testing the device, but you will want to use a microSD card formatted in exFAT format (mine came preformatted). I got the green one, and instead of the neon green, with the TPU case on, it is more of a forest green. I was between this and the M300, and the battery life is worth not having an onboard speaker. Body is aluminum and glass, very high quality and durable build quality.

### ⭐⭐⭐⭐⭐ Review
*by R***N on 16 November 2025*

I bought this principally because I was going to have a time in hospital where wireless earphones would be impractical due to their limited battery life. the HyBy filled the brief having excellent battery life and provision for charging through USB as it plays. However, it was an excellent buy in so many other ways. It has no right to be so well built or sound so good for the money. It is significantly better than my 4-year-old IFI Hip Dac, Which is just a DAC. With all its many streaming features, the HyBy cost only slightly more! It uses Android, so one can use whatever apps you like, but the HyBy Music Player also has a 'Pure Mode' which bypasses the limitations for playing back high-res music built into Android. One can access. For example, one can access QOBUZ this way and it sounds excellent. There are also various equaliser options. There is a fancy custom one - I have forgotten the name of - which degrades the sound to my ears, but the parametric equaliser works excellently and has enabled me to tune the sound to my hearing and headphones very precisely. The headphone amplifier which can be used either single-endedly or in balanced form is surprisingly powerful and very good at conveying the dynamics of music. Although they are not an especially difficult load compared with some others, my £450 or so Grado RX2x headphones were driven well enough to give of the considerable best. The sound has very neutral tonality, very good dynamics as noted, and has a surprising amount of 'space' around it though this aspect of the sound is bettered when using the same headphones through my very much more expensive HiFi DAC and valve headphone amplifier. What is more the HyBy is not a bad streaming transport when used with the HiFi separates' DAC. It's even better when fed through my inexpensive SMSL gizmo which cleans up the signal using a better digital clock. All in all, quite a bargain!
