This is the correct way to open the HiBy R3II's gameplay!


1.Rotary Dial Gameplay

(1)Digital Audio Rotary Dial

I'm sure everyone has watched the tutorial video on how to use the R3II with MOJO and headphones, which was released some time ago, right?

Note: Both PO and LO are connected through the 3.5mm output. If you have devices that support line input/output, just connect them to the 3.5mm port.

(2)Wireless Audio Rotary Dial

The R3II can be used as a digital audio rotary dial, and similarly, it can also be used as a wireless audio rotary dial.

When we want to listen to songs on streaming media platforms (which offer more song choices), we can use our smartphones to remotely control the R3II through DLNA/Airplay functionality. We can connect the R3II to our decoding headphone amplifier (which can be a desktop computer or a portable player) and start using it!

2.Bluetooth Functionality

When using the R3II as a sound source, you can directly connect your headphones/speakers to it using its Bluetooth feature. But that's not all! The R3II has bidirectional Bluetooth functionality, so it can also be used as a Bluetooth decoding headphone amplifier.

By wirelessly controlling the R3II with your smartphone and connecting it to your headphones, you can achieve better sound quality compared to directly connecting your phone via Bluetooth. Additionally, you can enjoy the freedom of being untethered from cables. Why not give it a try?

Note: The R3II has bidirectional Bluetooth functionality and supports playback formats including: mp3, wav, ape, flac, dsf, dff, iso dsd, cue, wma, ogg, aac, opus, aiff.


3.Computer Peripheral Usage


In most cases, the sound quality of the built-in sound card on a computer is not as good as that of a HiFi player, especially for laptops or tablets. This is where our R3II comes in handy. You can use it as an external sound card for your computer. Simply connect the R3II to your computer using the original cable and install the driver. The sound will be fantastic!

(2) Computer Bluetooth sound card.

If you want to listen to Bluetooth speakers at home but your computer doesn't support Bluetooth or you don't have a Bluetooth receiver, what should you do?

In this case, all you need is to prepare R3 II and its original cable (a regular cable that supports file transfer will also work). First, connect R3 II to your Bluetooth speaker, then connect R3 II to your computer. The R3 II interface will display the song's sampling rate.

Note: Make sure to connect our R3 II player to the Bluetooth speaker/headphones first~


Note: R3 II can also be connected via an OTG cable or a card reader to directly play music from a storage card through the Type-C port. You need to adjust the system settings >>> USB Working Mode >>> Auto.
