Introducing the FiiO M15s: Desktop System to Go

FiiO has just launched the M15s, a high-end portable music player that offers exceptional audio quality and a whole host of innovative features. It's the perfect blend of desktop DAC/Amp capabilities with the convenience of a portable player. Let's dive into the details of this amazing device.

Desktop and Portable Dual Power Supply Modes

One of the standout features of the M15s is its ability to switch between desktop and portable power supply modes. This means you can enjoy robust performance whether you're at home or on the go. In dedicated desktop mode, the M15s transforms into a desktop device and works completely without the battery while under USB fast charging.

Five Gain Levels for Versatile Listening

FiiO has designed the M15s with five adjustable gain levels, making it easy to drive a wide variety of IEMs and headphones. You can choose from ultra-high, super-high, high, medium, and low gain levels when using battery power, or select the enhanced over-ear headphone gain level under USB power for undistorted power output up to 1200mW per channel.

Six Operating Modes for Every Audiophile

No matter your listening preferences, the M15s has you covered with six different operating modes:

  1. Roon Ready Mode: Certified Roon Ready for serious music

    lovers who want to use the M15s as an endpoint in their Roon setup.

  2. Bluetooth Receiver Mode: Use the M15s as a high-quality Bluetooth receiver, enabling wireless streaming from your phone or other Bluetooth devices.

  3. USB DAC Mode: Connect the M15s to your computer to experience high-resolution audio playback without the need for an additional DAC.

  4. Line Out Mode: Bypass the internal amp to use the M15s as a pure source for external amplification.

  5. Digital Out Mode: The M15s can serve as a digital transport, outputting digital signals to external DACs or other devices via SPDIF.
