FiiO's 6th-gen honeycomb design

The M11 Plus LTD inherits the well-received 3D cut designs of the M11/M11 Pro, while innovating with new hexagonal honeycomb design elements. The body and buttons of the M11 Plus LTD seamlessly come together in a design that is both exquisitely beautiful, yet bold and aggressive. This is one device that is sure to immediately catch your eyes.

The front low-pass filter, small signal amplification, and amp expansion circuit each have their own independent power supplies – all for achieving a stronger overall power supply for better dynamics. Additionally, many measures have been taken to ensure excellent temperature management – including independent shielding covers of different components, use of customized thermal silica gel and graphene, and nickel silver heatsinks all to absorb and dissipate heat as needed. Rock on without actually worrying your device will burn! 

Enhanced power supply

Rock on with heavenly sound

A grand finale of high-end chips Out-of-print AK4497EQ DAC

The M11 Plus LTD is equipped with 2 of the now out-of-production AK4497EQ DAC chips with their unique, soft, and natural charm that will allow you to rediscover your music all over again.

The parameters above came from the chip. For specific parameters of the device, please refer to the parameter list.

New generation interactive intelligent volume system,

Unique all-in-one volume button + touch panel

Let go of the traditional volume wheel, and embrace the volume button + touch panel. Not only does this volume panel take up less space (leaving more for other components), it also brings an unprecedented volume change experience either through precise adjustments with buttons or by sliding on the touch panel. 5 volume adjustment methods supported: Sliding on panel, buttons, touchscreen, FiiO Link, and Bluetooth remote control

Thanks to the ultra-small size of the volume adjustment system, the M11 Plus LTD contains a huge 6000 mAh battery with support for QC2.0/3.0/4.0 and USB PD fast charging. After a full charge, the M11 Plus LTD can be continuously listened to for 11.5 hours and can remain in deep standby for up to 1000 hours.

*The data came from comparisons with the M11 Pro (Type C port).

While the M11 Plus LTD can output a mighty 588 mW, there are 3 gain levels- low, medium, and high. Each gain level has 120 volume steps, allowing you to dial in the volume to exactly where you want. The M11 Plus LTD is perfect whether you are using high-impedance headphones or high- sensitivity earphones.

3 gain levels for all kinds of headphones

The M11 Plus  LTD contains the first iteration of FiiO's version of Android 10, with 137 icons redrawn, every detail customized and inspected, everything made sure to be beautiful yet intuitive. New functions such as dark mode, night mode, and three navigation options give you new ways to further enhance your media experience.

Master-quality sound reproduction

Global MQA 8x decoding support

The M11 Plus LTD supports decoding MQA tracks in 8x mode-allowing for rich, master-quality sound reproduction with high sampling rates in manageable file sizes.

Contrasting with the bold aggressiveness of the rest of the device is the delicate, exquisite diamond cut texture of the rear cover. Due to the refraction of light, looking at the back cover from different angles produces different looks for a gorgeous and delightful aesthetic.

Dazzling diamond cut textured back

Not all screens are created equal to a bezel-less one. The M11 Plus LTD has an upgraded 5.5-inch HD screen with even more gorgeous colors and an accurate color temperature. And its 18:9 screen ratio is the perfect combination of maintaining an excellent visual experience while making for a more comfortable grip.

10-band PEQ precise tuning
Born for good sound

The PEQ (Parametric Equalizer) function was designed for the M11 Plus, which supports 10-band self-defined tuning. On the FiiO Music App in the M11 Plus, users can self-adjust the frequency, gain level, Q value, etc., achieving more accurate frequency response among every frequency range while ensuring high-fidelity sound quality. It supports up to 192kHz/24bit under PEQ style.

*Enable PEQ through the FiiO Music Lab. After enabling, PEQ would replace the default EQ, of which each frequency band can be self-defined.
