Product details

Overview

The FiiO M33 R2R is designed for passionate listeners who want desktop-grade sound in a portable format. Built on the Qualcomm Snapdragon 680 with 8GB of RAM and 128GB of onboard storage, it delivers smooth multitasking, fast streaming, and ample space for your music library. This combination aims to provide reliable performance and long-term responsiveness beyond what many compact players offer today.

True R2R DAC with tunable sound profiles

FiiO’s first portable player centered around a self-developed R2R resistor ladder DAC captures a more analog feel while remaining highly precise. Users can switch between FLAT (neutral) and WARM (analog-inspired) modes to suit their headphones and listening mood.

Vivid visuals, light and comfortable

A 5.5-inch Full HD touchscreen (1080×2160) delivers crisp menus and artwork, with cassette, spectrum, and VU meter themes enriching your listening ritual. Weighing about 258g and featuring an AG matte glass back, it’s designed for confident daily carry and extended sessions.

Smart tuning and customization

AUTO EQ automatically aligns headphone frequency curves for precise, lossless tuning. In addition to built‑in presets, you can fine‑tune with manual EQ options to match your headphones and personal taste.

Powerful headamp and analog clarity

The device uses fully differential TI analog circuitry with four INA1620 headphone amplifiers, delivering up to 1100mW per channel in balanced mode. This setup supports both efficient IEMs and demanding full‑size headphones with clear, spirited output.
