    Dedicated desktop mode

    When in the dedicated desktop mode and under USB fast charging, the M15S will transform essentially into a desktop device and work completely without the battery. That is, under this mode the battery will neither be charged nor discharged, preventing premature battery degradation.

     

    Desktop/portable dual power supply modes

    The M15S not only features the “desktop/portable dual power supplies” as seen in other FiiO products, it is also equipped with an automatic “auxiliary DC power supply” – the M15S is able to automatically recognize when fast charging* through USB is being used and automatically switches to use the highest-voltage power supply, leading to an increase of 26.67% in power supply for even more power output. Even when not using the fast-charging adapter, the M15S can still automatically switch to a higher-voltage power supply that is enough to drive most headphones.

    *Activated as soon as it detects QC/PD fast charging through USB

    Power supply increase of 26.67%, Power output increase of 21.21%

     

    Five gain levels

    The M15S can be adjusted with five levels of gain. Under battery power, low/medium/high/over-ear headphone gain levels can be selected. When under USB power, the enhanced over-ear headphone gain level is also available, enabling undistorted power output up to 1200mW per channel, easily enough to drive a wide variety of IEMs and headphones.

     

    Six operating modes including Roon Ready

    Pure Music mode: FiiO exclusive mode, for immersive music

    Android mode: Freely use third-party apps, including those of streaming services

    AirPlay mode: wirelessly connect to iOS devices like iPhone/iPad, with a sound quality boost

    Roon Ready mode*: Roon Ready certified, for serious music lovers

    USB DAC mode: acts as a DAC when connected to a computer/phone, for greatly improved sound

    Bluetooth receiver mode: supports SBC, AAC, aptX, aptX HD, aptX LL, LDAC, and aptX Adaptive, for convenient quality wireless sound

    *Roon Ready mode will be added with future updates

     

    Overbuilt power supply for ample clean power anytime

    Fully separated digital power supply, effectively reducing crosstalk and interference

    Multi-stage analog power supply, high-precision and low-noise for early signal processing

    Multi-voltage servo power supply for headphone amp, capably driving low and high-impedance loads

     

    High-performance ES9038PRO DAC

    The full, uncut desktop ES9038PRO DAC chip with eight independent D/A converters is employed in the M15S. Each channel uses four D/A converters in parallel to form a fully differential output, for a truly rich and highly resolving sound.

     

    4th-gen FPGA+NDK femtosecond crystal

    Audio data is passed through a FiiO-developed 4th-gen FPGA with phase-locked loop technology, which works together with two custom Japanese NDK femtosecond crystal oscillators to provide a high-precision and low jitter unified clock source for the entire audio architecture. This is all done in the pursuit of purer sound.

     

    Multi-stage audio circuit

    The M15S features a multi-stage audio circuit complete with IV, LPF, gain adjustment and amplifier sections. High-precision and low-noise film resistor used ensures more accurate signal reproduction and channel balance. Within the LPF part of the circuit are Panasonic low-loss metalized film capacitors that guarantee extremely low harmonic and phase distortion. 

     

    Graphene heat dissipation technology

    Advanced and highly efficient heat dissipation design allows the M15S to maintain stable temperatures and continuously deliver high power output:

    Stainless steel battery compartment, to quickly dissipate battery heat;

    Low temperature-drift and high-precision thin-film resistors and capacitors, that can stably cope with temperature swings;

    A dedicated metal shield, graphene, and high thermal conductivity silica gel over hotspots for maximum heat dissipation.

     

    Comprehensive shielding for truly “clean” sound

    In order to shield from interference as much as possible, the M15S employs a nickel copper shield that shields the analog portion of the audio circuit as well as the main SoC to ensure the purity of the analog signals traveling through the circuit. In addition, stacked onto the main shield are other heat dissipation and shielding materials as well as wave-absorbing paper. The high-quality parts and carefully-considered shielding design all aim to ensure truly clean and highly-resolving sound.

     

    Wireless HiFi taken to the next level

    The M15S wireless capabilities include AirPlay, DLNA streaming and transmission, as well as Bluetooth. Bluetooth is handled by the Qualcomm QCC5124 chip that has a proven track record in other FiiO products, allowing the M15S to capably handle 2-way Bluetooth.
    Bluetooth 5.0 supported transmission: SBC, AAC, aptX, aptX HD, LDAC, LHDC
    Bluetooth 5.0 supported reception: SBC, AAC, aptX, aptX HD, aptX LL, LDAC, aptX Adaptive

     

    Knob/button volume adjustment

    Volume on the M15S can be adjusted either with an analog potentiometer knob or with buttons, both easily allowing you to fine-tune through the 120 levels of volume the way you prefer.

    Feel free to turn the volume knob to your heart’s content, as the integrated rotary encoder* is highly precise and designed for minimal wear with each turn of the knob. Even if you accidentally drop the device, the encoder is securely fixed ensuring the continued reliability of the volume knob.

    *The volume knob features RGB lights, which can be customized in brightness, color, and behavior under various device statuses.

    *Encoder rated durability>30000 cycles (360° forward rotation+360° reverse rotation is 1 cycle)
