.
Dual 8-Channel ESS ES9039SPRO DACs
The FiiO M27 integrates two ESS ES9039SPRO DACs, reference-level chips with ultra-high dynamic range and extremely low distortion. The configuration uses dual-channel ultra-low-noise ES9312 regulators to support the two DACs, with four independent power supplies dedicated to the differential modules. The result is audiophile-grade sound reproduction: transparent, detailed, and free of background noise, ideal for high-resolution recordings.
.
Five Hardware Gain Levels
The FiiO M27 offers significant improvements in power and voltage at every gain level and with any impedance. This ensures authoritative drive with both sensitive IEMs and full-size, high-impedance headphones. With a fast charger connected to the dedicated port, Ultra High Gain Mode activates, unleashing over 5000 mW per channel, allowing the M27 to effortlessly control even the most complex dynamic passages.

Safe 9200 mAh Battery + Hardware/Software Protection
The player uses a high-voltage 9200 mAh battery, designed with advanced hardware and software protection systems. It supports 35W fast charging compatible with QC3.0, QC4.0, PD2.0, and PD3.0 PPS protocols. Approximate battery life:
• Single-ended output: approximately 9 hours
• Balanced output: approximately 8 hours
.
Removable Battery
The battery module is removable and replaceable, reducing the risk of long-term degradation and extending the life of the device.
.
The battery pack is not sold separately; replacement is required through an authorized distributor.
.
Patented Desktop Mode
Desktop Mode allows you to completely bypass the battery, preventing charge/discharge cycles during high-power use. This reduces battery wear and extends its life.
.
Proprietary 6th-Generation DAPS System
The sixth-generation DAPS (Digital Audio Purification System) introduces a high-capacity FPGA combined with two ultra-precise femtosecond oscillators. This architecture ensures extremely low-jitter digital transmission and a highly stable clock, resulting in purer, more defined, and natural sound.
.
31-Band Lossless PEQ + AUTO EQ
The FiiO M27 is the world's first DAP to support 31-band lossless PEQ, enabling extremely accurate sound customization using FII's proprietary algorithms. This system allows you to simulate or correct the frequency response of your headphones, adapting it to your target curve or personal preferences. For those who want instant adjustment, the following are available:
• AUTO EQ based on the original headphone data
• Sound presets (Pop, Jazz, etc.)
• The dedicated "FX17 Relaxed Sound" EQ for even richer and more enjoyable listening.
