If you are looking for an ideal portable MP3 music player, you will not miss the HiBy R6 Pro II. The HiBy R6 Pro II is a new Android 12 digital audio player with a dual AK4499EX +AK4191EQ DAC and a beautiful design. This player is aimed at in-ear monitor lovers who want a precise and detailed sound with a rich bass texture. Let's take a closer look at the device and see what it can do.

The HiBy R6 Pro II has a gorgeous 5.9-inch 1080p Corning Gorilla glass display, coated with an oil-repellant material. Unlike most DAPs, HiBy went for an adventurous asymmetrical design, which supposedly aids in grip. The design on the back of the DAP is supposed to reflect sea waves meeting the night sky.

The player has a Qualcomm Snapdragon 665 processor, which makes it fast and smooth to operate. It also has 4GB of RAM and 64GB of internal storage, which can be expanded with a microSD card up to 2TB. The battery life is impressive, with a 5000mAh capacity that can last up to 15 hours of playback or 50 days of standby.

The HiBy R6 Pro II supports a wide range of audio formats, including DSD512, PCM 32bit/768kHz, MQA, and native DSD output. It also has two-way Bluetooth 5.0 with LDAC, aptX HD, and HiBy's own UAT codec. The player can also act as a USB DAC or a Bluetooth receiver for your computer or smartphone.

The most interesting feature of the R6 Pro II is its dual AK4499EX DAC architecture, which uses a discrete I/V stage and a resistor-switching mechanism to achieve a high-performance and low-noise output. The player has two headphone outputs: a 3.5mm single-ended, a 4.4mm balanced. The output power is relatively low compared to some other DAPs, but HiBy claims that this is intentional to provide better control and accuracy for IEMs.

The sound quality of the HiBy R6 Pro II is excellent, with a slightly laid-back and smooth signature that is perfect for melodic techno tracks and smooth jazz tracks on the go. The bass is deep and textured, with good impact and extension. The midrange is clear and natural, with good vocals and instruments separation. The treble is detailed and airy, without being harsh or sibilant.

The HiBy R6 Pro II also has some advanced DSP features, such as MSEB (Mage Sound Eight Ball), which allows you to tweak various aspects of the sound such as bass extension, vocal thickness, treble brightness, etc. You can also use HiBy Link to control the player remotely from your smartphone.

The HiBy R6 Pro II is priced at $749 USD, which is quite competitive for its features and performance. It also comes with a free storage case BA04 if you order it now from Volkchoi's website.
