User Experience
The HiBy R4 is an Android 12-based device that offers a fast and responsive experience. It is user-friendly and has a solid battery life, a common feature in HiBy products. The design, software, and overall user experience of the HiBy R4 are refined and well-executed.
The player has a responsive HD IPS screen, providing a fairly good user experience. Although the resolution is not the best by today’s market standards, it is still more than enough, especially considering the device’s price tag.
The HiByOS, a custom Android rebuild, is optimized for bit-perfect audio, bypassing the Android’s limitations and SRC through their Direct Transport Audio Architecture. Any app can benefit from the integrated DACs to the fullest extent.
HiBy has paired the SD665 with 3 gigabytes of RAM, sufficient for daily use. The device operates smoothly and quickly, without any stutters or freezes. The sample rate is always visible on the right side of the notification bar, and the LED light above the screen lights up in different colours, depending on the sample rate. The streaming apps work flawlessly with bit-perfect playback.
One exciting feature of the HiBy R4 is the option to flip the screen and have the audio jack on top or bottom, depending on your choice.
HiBy Music App
If you’re looking for an application to play songs from your music archive, HiBy Music is a great option. The app works perfectly and doesn’t have any major drawbacks. I particularly like the screen that displays your recently played songs, which makes it easy to return to frequently played tracks.
Another great feature of the app is the Wi-Fi music-importing menu. If your PC or smartphone is connected to the same Wi-Fi network, you can transfer your music files over the air by copying the URL onto your browser. However, keep in mind that wired transfer is faster than over Wi-Fi. Nonetheless, this is a nice addition to the app’s functionality.
Accessing your folders, artists, and genres is effortless from the main screen of the HiBy Music app. The app also provides the HiBy Link option, which enables you to connect with other devices. One of the most important features is the search option, which is available and easy to use. You can also download lyrics and album art for any song you want, a neat touch from HiBy.
I found the app’s interface simple and easy to navigate, with a well-organized menu. Although a theme customization option would be a nice addition, the app’s design is still pleasing to the eye. To sum up, the HiBy Music app is a reliable software with everything you might need.
MSEB
The HiBy Music application has an MSEB menu “MageSound 8-Ball”. This menu allows you to adjust the sound beyond the basic 10-band equalizer, and it’s a trademark of HiBy. You can tweak almost every aspect of sound, from the overall temperature (cold to warm), bass extension (light to deep), bass texture, note thickness, vocals, sibilance, air, and more. It’s a great feature to play around with, and you can make any headphone work with this DAP.
Although I don’t like to fiddle with DSP settings, it’s worth mentioning that this is another important aspect of HiBy R4. Overall, the software is excellent and you can use the HiBy Music app with devices from other brands.

Hello
I am wondering how it can have a two dimensional soundstage as mentioned in the Cons.
Within the last 2 Decades every little piece of Audiogear had an even wider Soundstage than it’s predecessor. So in my logic, the generell Soundstage of Audiogear today, should be wide as the distance from here to the end of all galaxies and back, 3 times.
So this DAP has to be exceptionally bad if it’s only doing this 2 dimensional.
As we are in 2024, I want to state that this is my sarcastic opinion of something that I care about.

Nu e rau. Sunet bun, dar se incalzeste foarte tare dupa numai o ora de ascultat muzica.
Nu l-as mai cumpara
