The HiBy R1 is a budget-friendly DAC/amp dongle that aims to deliver a clean and enjoyable listening experience for those on the go. Designed with portability in mind, it boasts the trusted Cirrus Logic CS43131 DAC chip, which is known for its efficiency and clarity. But how does this compact device hold up in real-world usage, especially when paired with more demanding IEMs like the Letshuoer S12? Let’s dive into the details.
Build Quality and Design
The R1 is lightweight and compact, making it an ideal companion for everyday use. It features a 3.5mm single-ended output, which might feel limiting to some users, but its simplicity is part of its charm. The hardened plastic casing adds durability while keeping the dap portable. There’s no unnecessary bulk, and it connects seamlessly to smartphones or PCs via USB-C.
Technical Specifications
• DAC Chip: Cirrus Logic CS43131
• Output Power: ~70mW @ 32Ω
• Output Type: Single-ended 3.5mm
• Frequency Response: 20Hz – 40kHz
• File Support: Up to 32-bit/384kHz PCM and DSD128
• Power Source: USB-powered and battery
• Compatibility: Android, Windows, macOS
Sound Signature
The HiBy R1 delivers a warm and musical sound signature, focusing on smooth playback rather than analytical precision. Its tonal balance leans slightly toward a softer presentation, making it a comfortable option for extended listening sessions. However, its power output limits its ability to handle more demanding headphones or IEMs at their full potential.
Bass
• The bass response is tight and rounded, with an emphasis on mid-bass. Sub-bass is present but lacks the depth and impact needed for bass-heavy tracks. While sufficient for most IEMs, it can feel restrained when paired with planar magnetic drivers like the Letshuoer S12.
Midrange
• The midrange is clean and natural, offering good separation for vocals and instruments. Vocals feel intimate, though there’s a slight lack of transparency compared to higher-end DACs. It handles acoustic and vocal-heavy genres particularly well.
Treble
• The treble is polished and non-fatiguing, but it lacks the sparkle and airiness of more powerful sources. High-frequency details are present but somewhat subdued, which could make complex tracks feel slightly less engaging.
Performance with Letshuoer S12
The Letshuoer S12 is a planar magnetic IEM known for its linear sound and efficiency. Paired with the R1, the S12 delivers a pleasant listening experience but doesn’t reach its full potential.
• Bass: Controlled but lacks the planar punch expected from the S12.
• Midrange: Smooth and coherent, with natural timbre but a slight lack of transparency.
• Treble: Detailed but somewhat rolled off, reducing airiness in upper frequencies.
• Volume Output: The R1 drives the S12 adequately at moderate volumes, but it falls short when pushed to higher levels, especially in bass-heavy tracks or complex orchestral passages.
Comparison with Questyle m12i and HiBy R4_
When used as a source for the Questyle m12i, the R1 offers a clean and sufficient signal, allowing the M12 to do the heavy lifting in terms of amplification and DAC performance. The difference between the R1 and the more powerful R4 becomes less noticeable in this setup due to the Questyle m12i’s ability to process and optimize the signal.
However, when driving the S12 directly:
• The R4’s higher power output (350mW @ 32Ω) gives it a clear advantage in dynamics, sub-bass extension, and overall resolution.
• The R1 still performs respectably, especially for its price, but lacks the authority and detail that the R4 brings to demanding IEMs like the S12.
Pros:
• Lightweight, portable design
• Clean and smooth sound signature
• Excellent value for the price
• Compatible with multiple platforms (Android, Windows, macOS)
• Low power consumption
Cons:
• Limited to single-ended 3.5mm output and usb c out.
• Lacks the power needed for demanding headphones or planar IEMs
• Treble detail and transparency are slightly restrained
• Sub-bass impact is minimal
• Streaming needs an overhaul
Hiby R1 Review Conclusion
The HiBy R1 is a great entry-level dap or dongle – dap for those looking to enhance their listening experience without breaking the bank. It excels with low-impedance IEMs, offering a clean and musical sound that’s easy to enjoy. However, it’s not without its limitations—its power output and treble extension may leave demanding audiophiles wanting more.
For casual listeners or those with efficient IEMs, the R1 is a solid choice. But if you’re looking to drive more power-hungry planar magnetic IEMs like the Letshuoer S12, a step up to a more powerful DAC/amp or pairing the R1 with something like the Questyle m12i might be a better option. At its price point, the R1 delivers a respectable performance and proves that you don’t need to spend a fortune for good sound. However, every other Hiby we reviewed has special places 😉
