FiiO M15S Desktop/Portable Hi-Res Digital Audio Player
The Power of a Desktop Setup. The Freedom of a Portable Player.
The FiiO M15S is an evolution of the classic M15, engineered to blur the line between portable convenience and desktop performance. It acts as a pocket-sized powerhouse, delivering the robust energy required to drive demanding over-ear headphones while remaining compact enough for your daily commute.
Powered by the legendary ESS ES9038PRO DAC (a chip typically found in high-end desktop equipment), the M15S offers an uncompromised listening experience with elite-level resolution and dynamic range.
Key Features & Highlights
-
Desktop/Portable Dual Power Supply Modes: This is the game-changer. When connected to the included fast-charging adapter or the DK3S dock, the M15S activates "Desktop Mode," bypassing the battery to deliver a massive 1200mW+1200mW output power. It drives hard-to-power headphones (like the Sennheiser HD600/800s) with ease.
-
Flagship ES9038PRO DAC: Utilizes the 8-channel desktop DAC chip for ultra-low distortion (THD+N <0.0003%) and a pristine noise floor. Every detail of your music is rendered with crystal clarity.
-
Snapdragon 660 & Android 10: Experience a lag-free, smartphone-like interface. Install your favorite streaming apps—Spotify, Tidal, Qobuz, Apple Music—and enjoy bit-perfect playback thanks to FiiO's global SRC bypass.
-
Five Gain Levels: From "Low" for sensitive IEMs to "Super High" for planar magnetic headphones, the M15S adapts to your entire gear collection.
-
Full Wireless Capability: Supports two-way Bluetooth 5.0 with high-res codecs (LDAC, aptX HD, aptX Adaptive) and dual-band WiFi for seamless streaming and Roon Ready integration.
Why Choose the FiiO M15S?
1. No More "Stacking" Required
Audiophiles often carry a DAP strapped to an external amplifier to get enough power. The M15S eliminates this bulk. Its internal amp is powerful enough to stand alone, giving you a clean, one-device solution.
2. Advanced Heat Dissipation
High power means heat. The M15S uses a stainless steel battery compartment and graphene heat dissipation technology to keep the device cool, ensuring consistent performance even during long listening sessions in High Gain mode.
3. A Visual & Tactile Joy
Features a classic volume knob with an RGB indicator light, a responsive 5.5-inch HD display, and a "dragon scale" textured rear panel that feels premium in the hand and resists fingerprints.
