The FiiO M27 
Guided by the “Neutral Grandeur” acoustic philosophy, the M27 evolves from the “portable desktop” of the M17 with next-generation specifications next-generation performance and fluidity, redefining the benchmark for portable Hi-Fi players. 

Elite computing power: QCS6490 (Snapdragon 778G architecture) 
While most Hi-Fi players still rely on the Snapdragon665, the M27 is a pioneer with the QCS6490 (with Snapdragon 778G architecture). Combined with Android 13 and 8 GB RAM + 256 GB storage, it delivers a quantum leap in speed and responsiveness. 

Unsurpassed Bluetooth: Qualcomm QCC5181 
The M27 supports the aptX Lossless Bluetooth codec, making it the first hi-fi player to enable lossless Bluetooth reception. 

Flagship DAC: Dual ESS ES9039SPRO 
With two ESS Sabre Pro ES9039SPRO DACs featuring 32-bit Hyperstream IV architecture, the M27 achieves an extremely wide dynamic range, virtually no distortion, and lifelike audio details with impressive realism. 

State-of-the-art DAPS technology: Brand new high-capacity FPGA + two RIVER femtosecond crystal oscillators 
The M27 is the first device to feature FiiO's sixth-generation DAPS (Digital Audio Purification System) and utilizes a high-performance FPGA in combination with RIVER femtosecond crystal oscillators. This advanced architecture creates a unified clock source with extremely low jitter while providing enhanced signal processing capabilities that ensure perfect audio reproduction throughout the entire signal chain. 

First use of titanium alloy as in smartphones + glass fiber back panel technology A titanium alloy case is available as an option. Combined with a high-strength glass fiber back panel, which is also used in smartphones, the M27 combines a high-quality texture and feel, truly embodying a flagship product. 

Unsurpassed performance: 5000 mW + 5000 mW balanced output power 
Equipped with 5-step hardware gain control, the balanced output in ultra-high gain mode delivers an impressive 5000 mW + 5000 mW of power, effortlessly driving most over-ear headphones on the market. 

Comprehensive I/O ecosystem 
In addition to 3.5 mm, 4.4 mm, and 6.35 mm headphone outputs, the M27 is also equipped with a standard coaxial input/output and a standard optical output, making it compatible with a wide range of devices. This makes it ideal not only for combining with various front-end or back-end devices to build a hi-fi system, but also as a reference device for sound optimization. 

Expandable masterpiece: Two microSD card slots 
Two high-speed microSD card slots (supporting up to 2 TB + 2 TB) ensure instant access to extensive music libraries and bring every classic in your collection back to life. 

Unmatched battery performance 
The M27 is equipped with FiiO's patented desktop mode, allowing it to function as a desktop device while extending battery life. In addition, the powerful 9200 mAh high-voltage battery can be replaced by the user. Thanks to the unlimited battery life, you no longer have to wait long for charging. 

Reference-grade audio architecture 
At its core, the M27 features a sophisticated six-stage desktop-class audio architecture. This system combines two ES9039 DACs with two ES9312 power regulators in a quadruple independent power supply configuration, achieving an exceptionally low noise level. 
Precision is further enhanced by two NJU72315 digital volume control chips and OPA2211 high-performance operational amplifiers, which work together to deliver stable, reference-quality audio output.
