APRAŠYMAS

From desktop to portable, the evolution of R2R

We've taken our proprietary R2R resistor array originally designed for desktop equipment, and brought it over to a portable player for the first time.
Shaped by the ears of expert acoustic engineers and perfected through feedback from the global audiophile community, it delivers the ultimate listening experience:
The unmistakable, lush analog warmth traditionally associated with R2R combined with balanced, high-fidelity performance.

Extensive storage, enduringly smooth performance

The Qualcomm Snapdragon 680 and an expansive 8GB RAM + 128GB ROM storage featured in the M33 R2R is unmatched in its class. Experience effortless streaming and seamless multitasking. It offers extra performance and storage to easily handle any future updates as well as to ensure a stable and durable experience for years to come.

Large 5.5-Inch HD Display, only 258g in hand

Like with the minimalist design featured on the FIIO M21, the sleek, refined lines of the M33 R2R create a sophisticated aesthetic. Clever engineering allows us to strike the perfect balance between size and ergonomics. It's not just about the impressive numbers on the M33 R2R's spec sheet, it's about that seamless, natural feel in your hand.

Carefully engineered audio circuit, powered by TI

The pre-amp stage utilizes TI fully differential op-amps for I/V conversion and signal conditioning, delivering a natural and expansive soundstage. The output stage features quad INA1620 amp chips in a parallel configuration. Thanks to these chips, the result is output power up to 1100mW+1100mW to effortlessly drive any headphone. Finally, the precision electronic volume control ensures that you experience explosive dynamics without losing a hint of detail.

15.5 hours ultra-long battery life, say goodbye to power anxiety

Featuring a premium 4400mAh high-capacity battery, both single-ended and balanced playback times are significantly improved over the M23. Low-temperature fast charging means the M33 R2R powers up quickly without overheating. Between the long-lasting battery and rapid charging, your music never has to stop.

Compatible with RETRO BOX, bring your own soundtrack wherever

It is the perfect match for the RETRO BOX cassette-style Bluetooth speaker, opening up another way to enjoy music. The versatile UI of the RETRO BOX allows it to serve as both a decorative desktop centerpiece and your portable soundtrack source.

*RETRO BOX is not included and must be purchased separately.
