FiiO M11 Plus ESS Overview

Nearly every aspect of the technology inside the FiiO M11 Plus Portable High-Resolution Lossless Wireless Music Player has been crafted to deliver audiophiles with a portable solution that's capable of reproducing a clean and authentic listening experience. To achieve this goal, FiiO incorporates their own Digital Audio Purification system (DAPS), dual ES9068AS DACs for incredibly low distortion, dual THX AAA-78 headphone amps for a live concert feel, and MQA 8x decoding for sound quality meant to match the master as closely as possible with compatible MQA files. There are also internal engineering touches made to reduce interference and offer a higher dynamic range, such as using independent power supplies and individual component shielding.

FiiO utilizes the LDAC, aptX, aptX HD, and AAC Bluetooth codecs for a high-quality Bluetooth streaming experience with most compatible devices. The M11 Plus also achieves both Hi-Res Audio and Hi-Res Audio Wireless certifications. When utilizing wired headphones, you're fully supported with three outputs: balanced 2.5 and 4.4mm, and an unbalanced 3.5mm. The 4.4mm headphone output also doubles as a balanced line output, and the 3.5mm jack also provides line output and a coaxial audio output. If you would like to utilize the power inside this handheld player to enhance your PC audio experience, you can use the M11 Plus as a USB DAC. All of this and more can be controlled via the integrated 5.5" 18:9 bezel-less display.

Attractive Angular Design
Retaining much of the design aesthetic of the M11 and M11 Pro, the M11 Plus incorporates FiiO's 6th generation honeycomb design elements, along with a diamond-cut textured back. This backing features multi-faceted light refraction, giving the M11 Plus different looks when viewed from various angles.
Robust Battery with Fast Charging
Listen all day long with a 6000mAh capacity battery that delivers up to 14 hours of continuous playback. When not in use, you can be assured the M11 Plus will be ready when you are thanks to a standby battery life of up to 1000 hours. Recharging such a powerful battery only takes approximately 3 hours, as the M11 Plus supports 27W smart fast charging, as well as USB Power Delivery 2.0 and 3.0, and Quick Charge 2.0, 3.0, and 4.0 technologies.
Intelligent Volume System
Precise volume adjustment can be achieved in five different ways. Use the sliding carbon fiber touch panel, built-in buttons, touchscreen, FiiO Link mobile app, or (optional) FiiO Bluetooth remote.
Fine Headphone Fidelity
The M11 Plus supplies a 588mW output with 3 gain levels: low, medium, and high. At each level, you get 120 volume steps, which is ideal for anyone pairing the M11 Plus with highly sensitive, high impedance headphones.
Customizable Shortcut Button
Execute complex functions with one button press, such as switching your EQ setting, randomizing the next track, deleting a song, and more.
5 Playback Modes
  1. PC USB DAC
  2. AirPlay via iOS
  3. Android mode
  4. Pure Music mode, separate from all other applications

The Fiio m11 plus sounds great and works very smoothly with the built in features. The only reason I did not rate five stars is that the bose connect app I downloaded for my bose ps1 speakers will not open on this android device. I emailed Fiio about this issue and they passed it on to their engineers. B&H offered to replace it but I don't think that would solve the problem. B&H was a great business to buy from and the free shipping was very fast. I highly recommend this store.

Will this be an overkill for me if I mainly listen to FLAC files converted from CDs?

Sorry for so many questions: I forgot to mention that I use iTunes on a windows operating system (10). Will this device allow me to transfer my entire library from my PC to an SD card?
Asked by: Marti
You can drag the song files directly from the iTunes app into a folder on your computer. Once there, you will be able to move the files onto an SD card.

How difficult is it to transfer a very large library from iTunes. I have about 30,000 songs stored on an SD drive. Is there an app that will transfer them all at once?
Asked by: Marti
I am not aware of app that will move your iTunes library into your Fiio M11. But you would easily be able to drag all the files from iTunes into a folder and then drag that folder into your Fiio M11.

OK, last question... if I store my music (100GB) on an external SSD drive, do I really have to put it on my laptop first? Is there a way to insert the SD card from the MP3 player into my laptop, and copy it that way , then insert into the MP3 player already loaded. I really do not want to load up my laptop with all this -- not even temporarily -- because there is only 140 GB free. The other alternative is abandoning iTunes for the Windows Media Player? Can this device sync with that?
Asked by: Marti
The FiiO M11 Plus Portable High-Resolution Lossless Wireless Music Player (B&H # FIM11PLUSESS) can technically interface directly with an external drive, but many users report audio quality issues for MP3 files transferred without a computer. According to the manufacturer it is recommended to transfer music through a computer, ideally through iTunes.
