FiiO M27: Portable Audio Player

The FiiO M27 is a portable digital audio player designed for listeners who want desktop-class performance in a travel-ready format. It uses Qualcomm’s QCS6490 processor, dual ESS ES9039SPRO DACs, and a fully balanced amplifier stage capable of delivering up to 5000mW+5000mW of output. Android 13, a removable 9200mAh battery, dual microSD slots, and extensive I/O give it a wide operating range—from a standalone player to a desktop hub or digital transport. Its design targets listeners who want a single device that can manage long sessions at home and still travel easily.

Processing that stays responsive

At the core of the M27 is Qualcomm’s QCS6490, a modern mobile SoC that keeps navigation, streaming, library management, and DSP adjustments moving without delay. The player pairs this with Android 13, 8GB of RAM, and 256GB of internal storage, creating an environment that behaves more like a compact smart device than a traditional DAP. Large PEQ tables, high-resolution files, and multi-app workflows run smoothly because the processor and memory overhead are built for that load.

Wireless playback through aptX Lossless

The M27 incorporates the Qualcomm QCC5181 Bluetooth chipset, enabling aptX Lossless for bit-perfect 16-bit/44.1kHz transmission. While Bluetooth remains a convenience feature rather than a replacement for wired listening, this codec removes the bandwidth compromises common to earlier profiles. It fits well for mornings moving between rooms or pairing the player with powered speakers across a workspace.

Dual flagship DACs for controlled, low-noise conversion

FiiO uses two ESS ES9039SPRO DACs in a fully differential configuration. This 32-bit HyperStream IV architecture supports high dynamic range and low distortion, characteristics that help maintain clarity during dense arrangements and complex transients. The DACs feed a balanced analog stage designed to preserve channel integrity and keep noise below the audible threshold. The result is a conversion chain that remains stable under load and scales well with demanding headphones.

Amplifier power for full-size headphones

The balanced output section delivers up to 5000mW+5000mW in Ultra High Gain mode. Five hardware gain levels give the listener control over noise performance with sensitive IEMs while still providing current reserves for planar magnetics. This range allows the M27 to serve as both a travel-friendly device and a transportable desktop replacement, making external amplification unnecessary for many pairings.

A flexible range of I/O

The player includes 3.5mm, 4.4mm, and 6.35mm headphone outputs alongside optical and coaxial input/output. This allows it to operate as a standalone player, a DAC feeding powered speakers, or a digital transport for an external converter. Because these interfaces are built into the chassis rather than attached through adapters, the device adapts cleanly to different listening environments.

Storage that supports large libraries

Two microSD slots—each supporting up to 2TB—provide room for high-resolution files, archival rips, multi-disc box sets, and long-term collections. Combined with internal storage, the player can hold extensive libraries without requiring rotation or compression. Browsing remains quick because the processor and memory are designed for large directory structures.

A removable battery built for long sessions

The 9200mAh high-voltage battery supports extended playback times and is user-replaceable. Desktop Mode lets the M27 run on external power without placing continuous charge cycles on the battery, preserving long-term health. When replacement is needed, the user can install a new unit without shipping the device for service, which is unusual in this category.

A six-stage architecture for electrical stability

Internally, the M27 uses dual ES9312 power regulators, NJU72315 digital volume controllers, and OPA2211 operational amplifiers. Together they create a clean signal path with stable voltage references. The volume controller maintains channel balance at low settings while the regulators help keep the noise floor low under fluctuating loads. This structure supports consistent performance across different gain levels and headphone impedances.

Clocking designed to minimize jitter

FiiO’s sixth-generation DAPS architecture combines a high-capacity FPGA with dual RIVER femtosecond oscillators. The FPGA manages data routing while the oscillators serve as the timing reference, reducing phase noise and jitter. This type of clocking environment helps maintain bit-perfect playback across formats and supports low-noise conversion at the DAC stage.

Optional titanium alloy chassis

An available titanium alloy body with a glass-fiber rear panel gives the player a rigid, durable shell. The denser material helps damp mechanical vibration and contributes to a solid in-hand feel. It is a structural choice aimed at long-term reliability rather than aesthetic differentiation.
