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

Legendary octa-core Snapdragon 660 Smooth smartphone-like performance

In the M11 Plus is a Snapdragon 660 with a 4 big / 4 small core architecture plenty capable of providing a smartphone- like smooth experience. Not only can the chip capably handle tasks like watching videos and playing games, it can also ensure ultra-low power consumption when only listening to music for better battery life.

Immersive live concert listening experience Neutrally pure amp architecture

Thanks to the feed-forward error correction technology and “neutral” design, the THX AAA-78 amps of the THX AAA Frontier series will let you experience every last sound and detail faithfully restored and placed in the soundstage, as if you were in the recording studio.

New anti-interference circuit design

The M11 Plus adopts a totally new internal layout and a modular circuit design. Each module of the circuit has its own shielding cover, which also means that the digital and analog portions are totally separated. This ensures that these parts do not interfere with each other and ultimately result in purer sound.

Enhanced power supply Rock on with heavenly sound

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 dvnamics. Additionallv man 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 if your device will burn!

All-new DAPS (Digital Audio Purification System) 4th-gen FGPA + NDK femtosecond crystal oscillator

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.

Go wireless HiFi SBC/AAC/LDAC two-way Bluetooth

Besides support for AirPlay and DNA streaming, newly added is support for the AAC codec for Bluetooth transmission and reception so that iPhone owners can also enjoy truly high fidelity wireless sound Bluetooth 5.0 transmission support: SBC/AAC/apt/aptX-HD/LDAC.

Bluetooth 5.0 reception support: SBC/AAC/LDAC.

Fiio’s 6th-gen honeycomb design

The M11 Plus 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 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.

Dazzling diamond cut textured back

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 aesthetics.

New generation interactive intelligent volume system
