The FiiO M27 is a Hi-Res Android audiophile digital audio player (DAP) with dual ES9039SPRO DACs, up to 5000 mW of power and desktop mode.

The FiiO M27 is an audiophile Android Hi-Res player (DAP) that extends the portable-device-for-desktop-use concept introduced by the M17. It combines a Qualcomm QCS6490 SoC (Snapdragon 778G architecture, A78 core up to 2.7 GHz), 8 GB of RAM and 256 GB of storage, two microSD slots and a 5.99-inch 1080x2160 screen in fifth-generation Gorilla Glass.
The conversion stage rests on two flagship 8-channel ES9039SPRO chips, backed by a 16-core XMOS XU316 USB interface. The M27 decodes up to 768 kHz/32-bit and native DSD512. Its sixth-generation DAPS system combines a high-capacity FPGA with two RIVER femtosecond crystal oscillators for very low-jitter digital transmission.
The M27 delivers up to 5000 mW + 5000 mW into 32 ohms balanced in ultra high gain mode, spread across five hardware gain levels and the HYPER DRIVE amplification circuit. It offers 3.5 mm, 4.4 mm balanced and 6.35 mm headphone outputs, plus coaxial and optical outputs. Desktop mode bypasses the battery to limit its wear.
A removable 9200 mAh battery provides the runtime, with 35 W fast charging compatible with QC and PD. A 3D cooling system with a graphite vapour chamber and graphene pads dissipates heat inside a metal chassis. The M27 adds a 31-band parametric equaliser with AUTO EQ. This version is made of TC4 titanium alloy.
