Why are Hi-Fi Audio Player Still Relevant & The Fiio M21 Is The One To Get
And Why the FiiO M21 Is the Best Affordable Upgrade for Music Lovers
In 2025, it’s tempting to believe that smartphones have fully replaced the need for dedicated audio devices. After all, your phone can stream, store, and control music with a few taps. But if you truly care about how music sounds—its detail, warmth, and clarity—a dedicated Hi-Fi audio player still holds major value.
Dedicated Digital Audio Players (DAPs) are built with one mission: delivering the best listening experience possible. They're not burdened by multitasking, bloated software, or hardware compromises like smartphones. And among this new generation of players, the FiiO M21 stands out as one of the best midrange options for audiophiles on a budget.
If you're coming from a more basic player like the FiiO JM21 or Sony NW-A306, the M21 offers a meaningful upgrade—richer sound, more power, and greater versatility, all without crossing into luxury pricing.
Why Dedicated Hi-Fi Players Still Matter
1. Better Sound, Built for Music
Unlike phones, which prioritize efficiency and form factor, Hi-Fi players use high-end DACs and amplification to bring out every sonic detail. You get wider soundstage, deeper bass, and clearer highs.
2. High-Resolution Audio Support
Most phones compress music or downsample audio. DAPs like the M21 support formats like FLAC, ALAC, WAV, MQA, and DSD—so you're getting the full, uncut experience the artist intended.
3. Distraction-Free Listening
With a dedicated player, music is front and center. No emails, notifications, or doomscrolling. Just pure immersion.
4. Protect Your Phone Battery
Using a DAP for music means your phone stays charged longer for what it does best—calls, maps, and communication.
5. Powerful Outputs for Serious Headphones
The M21 features both balanced and single-ended headphone jacks, delivering real driving power—something phones can’t match without bulky dongles or external amps.

This is where the M21 flexes its muscle. The dual ESS DACs provide a wide, dynamic soundstage with stunning resolution. Instruments feel separated and lifelike. Bass is textured, not boomy. Treble is crisp, but never harsh. Whether you're using IEMs or over-ears, the M21 makes them shine.

Battery life holds up impressively for such a powerful unit, giving up to 15 hours of playback depending on your output and file type.
